Ampere is pretty amazing to check how much power that specific cable and charger is sending your phone. Found a few of the cables I had were faulty and gave less than 200 mA while my stock one is 1050 mA. Definitely something to have and keep on your phone. It is free with an IAP of $1.13 to remove and add a few features.

Step 1: Install Ampere for android. It will tell you the actual charging current, if your phone charging circuit can provide this information.
Step 2: If the battery temperature is over 40 °C, charging stops. Ampere will show you this. If it's the case for you, find a way to keep the phone cool.
Step 3: Replace the USB cable if charging a cold phone with the original charger and low display brightness doesn't give you a decent charging current (1000-ish mA). Micro-USB plugs (male end on the cable) wear out quickly, so I have found, especially if you're routinely handling the phone with the USB cable plugged in (it usually lasts a couple of months for me.) Unfortunately, most aftermarket cables are crap, so I have found. In the Netherlands, the 100 cm micro-USB cables from HEMA are decent.
I recently switched to Anker cables because of this.
If you don't have a usb power meter you can use an app on android called Ampere to measure charging current. Really useful.
Surtout, surtout, vérifie que ton câble est de bonne qualité. Cela peut faire une différence jusqu'à une charge 10 fois plus rapide.
Je te conseille d'installer Ampère pour tester ton câble. Tu dois avoir environ 1000mA (1 ampère) si ton câble est de bonne qualité.
Moi j'ai un câble qui charge seulement à 100mA, autant dire qu'il se décharge plus que ne charge, et un autre câble qui délivre du 1000mA.
Selon moi, c'est impossible que l'antivirus/le root/nettoyage de cache change significativement quelque chose.
I also have this problem since a few weeks. If you play a game, it discharges faster than it charges again. Even if it's plugged in and I'm playing some 3D game, it just stays at the same percentage.
According to Ampère the phone pulls only 250 mA with the standard 1A charger, but about 650 mA with the 1.5A charger that came with my bluetooth speakers.
Have you checked if it charges with the same amperage? In another thread they took an usb-c extension and while the phone said dash charging (3500mA) it charged with a lower current (50-25% lower).
You can use the App Ampere to check it.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
Can you settle some debate for us? Can you measure (using something like this) what the phone draws when using different charging combinations?
Specifically, we're trying to figure out of it's possible to draw 3A using the USB Type A -> Type C cable on a variety of Type-A chargers.
For the record, I'm of the opinion that you'll only get 3A/5V (15W) from a Type-C charger like what comes with the device, but there's confusion because Google's description for their Type-A to Type-C cable claims it can do 3A/5V - but no Type-A charger I've seen supports this configuration.
Last time I had a similar issue to this, it was my charging cable. Try different cables and AC adapters?
Consider using something like Ampere to get an idea of your charging current.
Highly recommend Ampere to see what current your phone is pulling. It's highly dependent on the quality of cable you use, interestingly.
Sorry to say, it's definitely a fake. The dead giveaway here is that so many certification numbers on your charger are filled with Xs, rather than being real certification numbers. UL Listings/Certifications in particular require numbers for verification, so the fact that your charger has none screams knock-off.
For example, yours shows the I.T.E. Power Supply as being XXXX, while the OEM charger in the video shows it was being 8D66.
On the bright side, it's a good thing you asked about this. You easily could have damaged/fried your device, depending on just how bad of a knock-off it is. You can use Ampere to check the specs.
It only does 2 things. Tells you your charging , and discharging rate unless you want to pay for the pro version. You see which chargers work best for your phone in real time, and then keep an eye on how much you're consuming. On average, I stay around -800mA to -1A, but apps like Snapchat or other power hogs have gotten me up to -2.2 A. You become more aware of how much energy you're using.
Edit: Forgot to add, idling, my Samsung Note 4 hovers between -70mA and -100mA. Just to give you some reference if you download it. You can catch the number when you turn your screen on before the refresh.
I use the Ampere app (https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en).
Also, while a cable may technically allow for QC, it may be under-engineered. I've never had issues, and a lot of safeguards would have to fail, but I figure it's worth mentioning that the really sketchy stuff can be dangerous.
Tip: For those who want to compare the update, just use the app Ampere to see how much energy and voltages are passing thru the cable.
Normally with USB-C to USB-C cables I got something like 4.1v and 2.5k mA. With normal cables I got 3.9v and 1.4k mA.
Edit: I'm with 8.0
Yes! It is called Ampere and is extremely useful.
When i tried it for the 1st time I got to the conclusion that my stock charger cable was able to deliver ~450mA while the cable from my powerbank went as high as 1100mA. Huge difference :)
This app is not even near to similar as ampere. only the colour combination looks similar in the main page.
Guess we are talking about this ampere https://play.google.com/store/apps/details?id=com.gombosdev.ampere
Edit: it is just one more type of RAM cleaner app
Power Delivery is always being used. The spec allows for lower and higher rates. Android will let you know if the rate is "slowly" or "rapidly" charging in the lock screen, or will just day "charging" if the phone hasn't negotiated with the power supply yet.
You can also use Ampere to monitor your charge rates. I only use the stock charger so I haven't had a reason to use it on my PH-1, but I can vouch for it from extensive experience with my microUSB phones.
I'd recommend you open the app while using the stock charger and let it sit in the foreground for a minute to settle. Take note of the voltage and current. You can compare those values to other cables/charger you come across. Note that your phone will charge the fastest when it's low battery and will charge slowly when it's nearly full. Don't be fooled into thinking a cable or charger are slow just because you're at 95% battery and your reference rate was taken when your phone was nearly dead.
Haven't used Pure Nexus ROM.. but it's possible they screwed up the label for charging and it's actually charging rapidly? Maybe download Ampere and verify the charging voltage: https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en
It should take about 1.5 - 2 hours to get to a full charge... so 2.5 hours isn't really that far off... are you getting decent battery life? It's possible an app is draining the battery while charging it, which is causing the charge time to increase.
The only other thing I can recommend is to flash a factory image and try it again. If it works, you can eliminate any hardware / charger issues.
- - Install Ampere
- - Run the app and monitor the charging rate.
- - Compare the charge rates for several USB cables and sources.
The results of an experiment i did a while ago revealed that:
- The USB cable that came with my phone charger only goes as high as 480mA.
- The USB cable that came with my powerbank goes as high as ~1100 mA.
I've tested on various sources (wall charger, powerbank and computer usb ports) and my conclusion is that the USB cables used have a significant impact.
Your problem may be related to the USB cables being used or even the battery that may be faulty. Try with other cables/batteries in order to isolate the problem and good luck :)
There will be. That's because on an average computer USB 1-2.0 ports are rated at 500mA and USB 3.0 ports are rated at 900mA. That's why you were getting a faster charge because the tablet was receiving +/- 400mA more than it was on previous charges with the 2.0 USB port.
Use the app Ampere, like /u/PCLOAD_LETTER mentioned. It's free and will tell you how much output your charging ports are giving your devices. I know on my computer with it's USB 2.0 ports I get about 450mA of output, while the Nexus' wall adapter will give me a little over 1amp of charging output.
Also the cables you use can make a difference in how much power the device receives. Some have higher output ratings than others and you could be limiting how much power your device has to charge without even knowing it. I learned that fact after using USB extension cables to charge my phone for over a year without ever realizing that it was reducing my charge rate by over 300mA. I still use them overnight since a slower rate isn't a bad thing for the battery, but when in a hurry I grab a single cable and a 2 amp charger.
You definitely don't need a Samsung charger. Any charger that's labeled Quick Charge 2.0 will work, as will Quick Charge 3.0 which is backward compatible with 2.0.
The issue is that different chargers and even cables will affect how much current your phone is able to accept. There's a huge difference and I use a great little app called Ampere which will show you exactly how much current you're getting. I have a couple dozen chargers and cables of all kinds that I've accumulated, and one evening I spent a couple of hours testing each combination of cable and charger. So many were just plain crappy and I threw those away, and identified all the gear that could provide sustained quick charging.
Did you try to use USB port in the dashboard? I think most of the time they're only really supposed to be used to connect a USB drive with music and are rated at only 500mA (while most chargers today have maximum output of 2A or more, with 1A at minimum). It's possible that the phone doesn't communicate properly with the car and tries to draw more than that, overloading the circuitry, which risks seriously damaging the multimedia system in your car. You can try an app like Ampere on your girlfriend's phone to verify how much current is the port supplying (just make sure the battery is in the range of ~20-80% - otherwise you'll likely get false readings).
What does ampere app tell you about the change current and is it in the ac charger mode?
Also are you using the original charger and/or the cable?
My extra long usb-c to usb-a cable with the factory adapter has in few occasions put my Nokia 8 into usb charger mode. In that mode my charge level was dropping instead of charging up.
However simply reconnecting the cable on either end fixed it.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
I got way into this app a while back. It shows exactly how much current is coming into your phone on charge, and you can see pretty big differences between cables. And of course different USB chargers are wildly different due to different charging specs, etc. But I was surprised that cables matter too. I threw out a few crappy ones.
Yes, a USB-C lead should charge the switch. Though just a heads up, unless you have a cable that supports a minimum of 1000 Ampere hours the charging will take a long time. Some cables that come with smartphones (for example) only have around 100 Ampere hours. So to test your cable, connect it to a power socket, connect it to your phone, then download and run an app such as Ampere.
In addition to what it says on the charger, there is also an app called Ampere that you can use while your phone is charging and it will show you about how much current the phone is getting. It's also handy for checking usb cables if you are curious as to whether or not they can handle higher amp charging or if they are even providing you with the rate you expect to get from the charger. Using the app, I found out a brand new 2 amp rated cable of mine was only giving me 300mA.
good to know and that's a steal, but for now i'm trying out an android app called Ampere that claims to show that.
i'm also leaning more towards something to measure the input voltage, as i may be adding batteries to the circuit at u/phineas1134's suggestion and don't want to feed it too much.
Use this to test your cable and wall socket while the phone is on. - Ampere – Android Apps on Google Play - https://play.google.com/store/apps/details?id=com.gombosdev.ampere
Do not worry about the paid options.
Then time your phone charge time while the device is off.
If your phone charges faster (like a lot faster) while off then you might have processes sapping your battery while charging or just normally.
Ampere only shows you the current charge to the battery. This means that anything being used by the device will lower the number. So that number will not be an exact representation of the cable and wall socket.
Hope that helps.
Screen off? Mine loses battery if the screen is on while plugged in. This phone really needs 2A+ for charging to be useful, especially when the screen is on.
Try Ampere to measure and check the phone is actually drawing current when the charger is in.
I'm not sure what you're asking here, are you asking how long it takes to charge or what amperage people are getting? There's no way you're pulling 8amps through Qi or wired charging.
You also don't need to use the hidden menu to do things like this. Just use Ampere.
Couple things
Here's my thread on WiFi battery drain.. you might be able to find some help in here. I just made some changes to the phone yesterday so I haven't seen results just yet.
https://www.reddit.com/r/Nexus5/comments/3xls4l/i_hate_to_add_to_the_bad_battery_threads_but_my/
Also on charging issues, I'd double check the MaH on the charger... I have so many laying around the house that work, sure, but are lower power and therefore charge slower, ya know. Maybe this app would be worth checking out to measure that kind of thing
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
Qualcomm quick charge is a proprietary thing, not the USB-C rated fast charging - not a surprise that that didn't work. The other ports were likely not saying "rapidly charging", but were probably pushing a faster charge than a "standard" USB port.
If you pick up Ampere you can monitor it precisely - e.g. the Qualcomm port from my Nexus 6 charger is pushing around 1900 mA, which charges noticeably faster than the 700-1000 mA that my normal car charger pushes.
Try a different micro USB cable.
Edit:
Install Ampere on your tablet, check to see at what rate it charges with different cables. Use the one that works best. I reccomend PortaPow 20AWG wire CHARGE ONLY cable.
Just use a normal car 12v input to 5v 2.4a output charger. Whats the point of using an inverter? I personally use Anker chargers, they are quality.
If after that and the tablet does still indeed draw more power then the tablet's charging circuitry can handle, which i doubt, buy a external Bluetooth GPS receiver. That will offload some power usage and they are more accurate, and can be placed somewhere remotely to get a better signal.
The original charger should be fine, but cables aren't all created equal. I use Ampere to compare the charging rate with various cables... Don't put too much stock in the absolute values displayed, just use it to compare. :)
I just checked my N7 now and it didn't indicate more than 740 mA with either the original cable or my phone cable. I tried both my Anker 5-port charger that I usually use, as well as the original N7 charger, no difference. My cables are both two years old though, so they could be flaking.
I noticed a similar issue with my replacement phone from Motorola, which switched me from 5.0.1 to 5.1.1. I didn't notice it though until after I sent my original in so I can't get much of a comparison.
Now, if it's an individual cable or charger that's giving you problems, Ampere (https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en) might help (I'm not affiliated with the app in any way). It let me know that the cable I was using to charge my phone in my car was failing, and not the adapter or car itself.
Hey, I'd recommend ampere, or a similar app. That app will tell you how fast your phone discharges, and how efficient charging is. My S5 charges at between 1200-1800 /hr. I can't say for sure, but my wife's g3 seems like it charges about as fast or even faster. So I'd say if you see a number >1200 you likely need a new cord or wall wart. You are charging it from the wall right? Not a laptop or wii or something? Anyway, here's a link to that app. https://play.google.com/store/apps/details?id=com.gombosdev.ampere
Might be worth it checking out how QC4.0 and PD charging works for a next revision. Check with an app such as Ampere if your phone actually draws close to 3A (while being pretty empty of course, otherwise it will draw less by design!).
there's an app called ampere that will measure the amount of power that the phone is using for charging (and discharging when unplugged) you can try both chargers and see the difference.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en\_US&gl=US
as with just about all USB charges there is a chip in the charger that communicates with the phone, to decide how fast to charge at. Unless the charger is broken or only uses a proprietary voltage, any USB charger will charge a phone.
I have tried an 87W apple MacBook charger and it says charging rapidly.
There are a couple of apps available that can provide insight into the charging/discharging rate/activity on your phone. Ampere can give you an idea of how fast your phone is accepting a charge as well as battery condition. (https://play.google.com/store/apps/details?id=com.gombosdev.ampere)
No personal interest, just something I tried to learn more about my chargers...
Best way to check whether a charger is running at Warp charge or normal charging speeds is to test a Warp charger using this application, and then compare it against other supposed "Warp" chargers.
Do you have any other USB devices plugged in into HUB ? Like usb keyboard/mouse/external HDD?
Out of curiocity, download this app and check charging stats. Share a screenshot. I will do the same when i will connect Note 9 to my DeX setup.
Download and app like ampere And see which able draws more current when you phone is around 20%
From the model number it seems both are rates 16w
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
There are different standards of fast charging, so it may be hard for the app to detect it.
If you want you can download Ampere to monitor your charging, with 25W fast charging you should get about 4000mA.
Ampere is what I have always used on my phones.
​
https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en_US
Also I don't believe that the issue is with the cable, cheaper cables just have shorter age You should test the cable using apps like this
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
The value there must be more than 800.. it changes every second but the changes must not be huge like 300
Install this -> https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en_GB Open it and while charging check what it says on the top of the screen. For instance just now when I connect my Note9 to my laptop via a very long cable it said 500 mah then dropped down to 200, this is excruciatingly slow and will take forever for my phone to charge. Connect it to your charger and see what the app tells you, compared to what is written on your actual charger as an output (it's most likely 1A or 2A if it's original). If there's a big gap then your charger is dying and you need to throw it away. On the other hand if your charger is crap (from a 2010s phone) then it will be slow. If the app says you're getting alot of amps but it's still slow maybe your battery is dying.
If you got the cable from Google, it should be fine.
Perhaps try an actual USB car charger that plugs into the cigarette lighter socket? (again, get one from a reputable company like AmazonBasics, Belkin, Anker, or one that's sold at a Best Buy store)
also, your car's USB port may not actually be outputting 1.5A... check it with this app:
https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en
Well the top 15% or so does charge more slowly to protect the battery. I haven't really looked at the estimated charge time myself but those are always pretty inaccurate. You might have a bad cable (more likely than the charger) try another if you have one.
Try installing Ampere: https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en_US&rdid=com.gombosdev.ampere
It's not super accurate but it should be somewhat close. I just checked I got ~1900 mA max charging but my battery is at 90% already. I'll try to remember and check when it's lower.
Avevo provato ma volevo qualcosa di rapido, non posso stare ogni giorno a fare una prova, anche perché se poi voglio vedere gli altri cavi che ho (ne avrò una decina) almeno con un app fatta bene posso verificarlo al volo.
EDIT: ora provo questa https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=it&rdid=com.gombosdev.ampere
Aye, I've used Ampere before. And recently installed AccuBattery but haven't tested it out properly yet. Any other good ones?
you could try software like ampere to get a general idea whats going on with charge and discharge. not super fancy like that usb, but works with some devices.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
Have you tried fast wireless charging? I have the Anker pad and charging is fast - I never bother to plug the phone into a charger even if I need a quick top up. Andoid Central said:
"On a Fast Wireless charger, our Galaxy S7 charged from 9% to 100% in just over two hours, cutting the total charge time in half. A quick look at power input through Ampere confirmed that Fast Wireless Charging was delivering almost exactly twice the amount of energy to the phone. This isn't quite as fast as a rapid charger, which will take this same Galaxy S7 from 9% to 100% in 90 minutes, but it's still pretty great when compared to the alternative."
Well, you could use Ampere and measure the charging current, I suppose anything above 2A would mean super charging.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
First thing I would recommend is to install Ampere (the free version does the job fine).
This gives you better data about how much power is coming in through the charger. Then try a few chargers and cables whilst keeping an eye on the avg/peak charging rates and see what you are getting.
I'll quickly go check what I can get and will edit in the answers (also running OPX with Lineage.)
Edit: The results are in. I had two chargers to hand, one OEM and one aftermarket. Neither cable was OEM I'm afraid though, that one broke for me a while back.
| Charger | Cable | Min | Max |
|---|---|---|---|
| OEM | 1 | 1150 | 1180 |
| OEM | 2 | 740 | 770 |
| Aftermarket | 1 | 1150 | 1180 |
| Aftermarket | 2 | 540 | 650 |
So obviously in this case the second cable is pretty bad, but both chargers were achieving a reasonable charge rate with a good cable. This is also comparable with the OPX charge rates on OOS, so it's not specifically a Lineage bug as far as I can see.
Maybe the charger is faulty after the power went down, it happened once to me.
Try another charger and this app to check the current. https://play.google.com/store/apps/details?id=com.gombosdev.ampere
I'll answer the last question. Of course. If you're curious about this stuff, you can get this app. https://play.google.com/store/apps/details?id=com.gombosdev.ampere
Even better would be to get an external tester.
> automation app macrodroid setup to alert me if the battery temp got over 95 degrees. > I also rarely ever charged past 80%, and never let it get lower than 20%. Batteries degrade much faster when nearly full or empty.
Ampere is another good app to automate all of this
~~It can also stop charging at a desired percentage.~~ The author has a blog going in to the technical details on why this should be done
Each one would vary in ways it would appear to the end-user. Motorola uses TurboCharge (TM), but also has support for QualComm QuickCharge. It uses a toast for notification of turbo charge based on Motorola - this page.
There are methods to measure draw in a pass-through fashion, but requires technical knowledge.
Play Store - Ampere is an app which will show current charging draw.
It looks like you already figured out that it's the cables, but this has also been my experience, as well. It's really weird, and almost entirely hit-or-miss. A nice, high-quality cable? Doesn't Quick Charge. A cheap cable I picked up at Walgreens? Quick Charge. Even on non-QC charging bases, I've found there to be huge differences in the charging rates between seemingly USB cables.
>How can I determine charging speed?
I used Ampre for this. Once I noticed there appeared to be what could be major differences between cables in charging rates, I went through all of my cables and tested them all using the same charger.
Any kind of air movement would help, yes.
Usually, phones don't get hot enough to worry while charging unless they are also doing stuff or the ambient air temperature is high.
As part of the protection systems in phones, they also cut the power if the internal temperature rises too much for safe charging. If the temperature continues to rise, most phones have a built-in shutoff to completely power down the device.
If you know the ambient air temperature is going to be pretty high and you don't have to charge the device quickly, you can temporarily disable fast charging.
If you touch the back of the phone (if it's glass or metal, but plastic is usually fine too) and it's almost too hot to touch, then it's best to power down the device and let it cool. The #1 way to kill a battery quickly is charging while too hot.
I recommend the Ampere app for android if you want to keep an eye on battery temperature and health.
First troubleshooting step is to use Ampere from Google Play Store to check the amount of power your phone is receiving. Download the app, plug in your charger and check the output. The output should be above 1500 mA if it's 'Rapid Charging', between 1000-1500 mA if 'Charging' and below 1000 mA if 'Charing Slowly'.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en
Yeah sorry not disputing the fact that C-C is different than A-C but my A-C will deliver up to 1900mA, as measured by Ampere ( https://play.google.com/store/apps/details?id=com.gombosdev.ampere )
Edit: added link
Can you still transfer data through the USB port? The port may be damaged in the inside. You can also try to measure the charger (which, if show a anomalously low rate, could be from the port damage).
Also pay attention to the USB cable! I use the original shield charger and ampere app to monitor the charging rate. Same charger with different cables will reduce the output to as low as a THIRD of the standard rate. Install ampere for free and check your cables! They might be a bottleneck.
Try using Ampere to see what the charge current is: https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en
And compare that to what it says when the phone is actually getting a charge. This will only show the total mA though. So if your phone is using 200mA while your charger is putting out 300mA then it'll only show 100mA. If you actually want to see what the charger is putting out you need a USB current meter: https://www.amazon.com/Soondar-Charging-Concurrent-Real-time-Smartphone/dp/B00ORNOWZK/ref=sr_1_2?s=wireless&ie=UTF8&qid=1473784282&sr=1-2&keywords=usb+current+meter
/u/Dekzter is correct. Not all USB ports put out equal voltage/amps, don't take our word for it. Download Ampere and see what each of your chargers is putting out.
Stock Android doesn't show "charging rapidly".
Try this app https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en
Depending on your battery level and temperature, it should go around 2000mah for you to say it's quick charging. Try it when battery is low for better measure.
I would recommend using the app Ampere to compare the current your phone receives with different cable/charger combinations, worked for me when I was deciding which cable to use.
Assuming you're using the original charger (unlike OP apparently), try other USB cables. Some are bad from the get go, others seem to go bad over time.
You can use the Ampere app (free) to compare the charge rate with different cables. Keep in mind the fuller the battery is the less current the phone will pull, so you'll want to test multiple cables back to back.
My suggestion would be to download the Ampere app and check the power output of the cable - it's possible there is a cable defect? That's my only guess.
It's a non-issue rather than a known issue.
Likely an algorithmic error in the battery stats. Use an app like Ampere to compare the charging rates of your phone's. I find that the current it draws is thermally-throttled drastically above 37ºC.
Install the app Ampere. It shows you exactly what you need to know about your battery. Check the battery health, connect your charger and check how many amps your tablet is getting from the charger.
Have you tried other chargers? Can you confirm the charger you are using works on, for example, your phone?
With Ampere you can "Measure the charging and discharging current of your battery". Maybe this helps you when trying different chargers for testing...
It's probably just the charging algorithm, designed to prevent overcharging and to extend the battery life. Your phone probably does reach 100%, but once it gets there it might stop charging. It'll probably wait for the the battery level to fall down to 90% before it starts to charge again. Most phones switch to trickle charging once it reaches 90% so the last 10% charging is pretty slow. Another possibility is that Wileyfox could have tweaked the algorithm in the OS so that the charge doesn't go past 90% when it's charging overnight.
You can confirm what exactly your phone is doing, by using a charge monitoring app like Ampere or Battery Widget Reborn, once your phone goes past 90%. Then check again once it reaches 100% and see if it's actually charging or not. Do this once during the daytime and once in middle of the night, to see if the charging behavior changes.
The power going into the phone won't change if you power it off. The only difference is that it'll use less power. A quick test with Ampere shows a net power gain (I'm very good at technical terms) of 2710 mA when charging using the included charger and cable with the screen on minimal brightness and while using wifi.
If the actual input when the phone is 3000 mA (I don't know and can't test it with my tools), that would mean charging with it turned off will only improve the speed by about 10%
Your phone has a SoC, which is capable of dynamically controlling volatge input. Once your phone detects the battery is nearing full, it will slow the intake down. Once your battery reaches 100%, it will begin sipping power to maintain the charge without overcharging. Your phone probably won't explode anytime soon, but I would still be wary using a tablet charger on a phone all the time.
That being said, you should only use OEM chargers on the device. Using a more powerful charger could damage the device. Try downloading Ampere. The app description has some great technical info and guides on batteries.
Get Ampere, it will tell you exactly how slow it is charging.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en
It might be just a case of a loose connector on the back. If you can just squeeze the back, that might help. If there is a hardware problem, you might have to replace the back altogether, which is fairly simple and cheap.
Are you using the original charger, right?
The G4 charges very slowly when the screen is on, and depending on what it's running, it may not charge at all, just slow down its discharging. Use this app to see how much power the phone is using and how much power your charger is providing.
I would simply suggest using Ampere to see what the different charge rates are between your LG charger and your new one.
Just a thought :)
not true - cable length, gauge, and shielding (i think?) can affect it as well.
Get Ampere off the play store and you'll rapidly see that one cable is not like another.
Download Ampere and see what its charging at. Youll probably have to activate the "old measurement method" to get it to read.
The charging cord matters, until recently I thought they could all work but after having a long charging issue with my Nexus 9, I downloaded Ampere and saw the amperage on the cable I was using was limited to 500mA.
I used heavier cable and my issue went away.
Edit: added a link
I had the same issue with a couple of one's I bought from ebay. The connection and metal quality is just not wide enough for many electrons to pass into the handset. You can immediately rule out the plug or cable using Ampere https://play.google.com/store/apps/details?id=com.gombosdev.ampere which will give you the real time current going into your battery (1.5a genuine plug over USB is as high as 1200mA while the fake magnetic ones will go no higher than 300)
It's convenient. I have a Qi Wireless charger at work and it gives me around 750-850mA. I don't have to plug it out every time I get a notification. I just it up, do what I have to, and put it back. Make sure to check the amperage on the charger as low quality charger would have less output. I use Ampere to check the amperage reading.
Here's how to check: download Ampere from the Google Play store and let it run. Now typically your phone will use around 300mA if the screen is on and the phone is basically at idle. So if they are charging at 1.8A, you should see a reading of about 1500mA or slightly more (up to 1800mA max but realistically up to 1650mA or so).
Hmmm..
Install Ampere from the play store - https://play.google.com/store/apps/details?id=com.gombosdev.ampere
This will at least give you some insight into what's going on. It should tell you whether the phone is recognising a charge via AC or USB, and the input its drawing from the charger.
There's an app called Ampere that says it measures the voltage and current coming in, I don't know how accurate it really is, but it might be worth a try.
Depending on the charger I use, anywhere from 500mA to 1500mA. Check it with Ampere. Linkme: Ampere.
It shouldn't take more than an hour or two.
Edit: Linkme didn't work because of a type, and I'm not sure it'll pick up my edit, so here: https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en
How are you charing? With the shipped Fast Charger (AC) or through USB from a PC/Laptop port? Also highly depends what is currently running on your device, if you set your display brightness to max and play games then even with the 2A fast charger you will only get maybe 1/4th out of it, maybe less...
There are apps to see how fast you charge, like Ampere, consider that it shows the current charge - what your device consumes... So if i put it charging through a normal USB port (normally about 500mA) it will show around 200mA
You can use Ampere to test out how much power is being transferred from your charger. On CM12 with the stock adapter and cable my G2 gets 1610 ma whereas my Nexus 9 using a higher output charger gets around 1020 ma from the adapter.
I'd suggest trying an app like Ampere to see what current is flowing to your phone with the turbo charger vs your standard charger.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
Keep in mind that it could also be the cable you're using with the charger.
I used to use Galaxy Charging Current, but I found an app called Ampere the other day, that does the same thing, but looks much nicer and displays some other useful stats too.
I am assuming you are using the official charging cable and wall charger? If so, have you checked to make sure that the cable is fine with either no cuts, terrible bends, the connection port itself or anything else?
If that all checks out fine, you could check and see if there might be something wrong with the USB port on your phone by using another cable.
You can also use this app called Ampere to check the charge rate of the cable plugged in.
Sure, and I suggest you to download this app (I am not the dev xD)
https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=it&gl=US&pli=1
In order to know the actual charging speed. And maybe answer to this comment with the response. I suggest to put in charge the phone when it has around 30% of battery or lower.
Can't find anything on your head unit model. You sure you go it right in your user flair? Kenwood DMX 43?
​
>I have the wire connected to a dashboard USB port meant for data transfer/charging to the AA device.
Have you measured the charging amperage through this add-on port? Although using an app like Ampere may not be accurate like a USB tester, it at least gives you a rough idea.
Have you tried a direct connection instead of through the USB port? Longer cable run may yield lower charging amperage. Some Kenwood have pretty long fixed usb lead so using another extension or aux port will surely yield lower amperage. A direct connection to Kenwood USB port should be able to draw 1.5A and depending on the phone, tasks, discharge rate, this may be enough not only to keep up with the discharge but also top up the battery. A direct connection is also more stable.
I use Ampre to see how much the phone is drawing from the charger. https://play.google.com/store/apps/details?id=com.gombosdev.ampere I tested all my old chargers to see which one puts out the most juice.
Es hätte mich sehr gewundert, wenn es tatsächlich die ganze Zeit mit 55W geladen hätte, die Hitzeentwicklung wäre mehr als merklich gewesen.
Man müsste den Ladestrom eigentlich aus den handyinternen Akkusensoren erschließen können (Auslesbar mit Apps wie dieser hier. (Ich habe diese App nicht getestet, nur kurz gegoogelt))
Übrigens vielen Dank für deine Antwort und Mühen, ich hatte eigentlich nicht damit gerechnet.
The faster you charge your phone the more heat is generated. Batteries do not like heat. So yes, the slower the charging the longer the battery will last.
As for slowing down your charging, check the settings. For figuring out how quickly your device is charging, you can try out Ampere or other similar tools, but I can't vouch for their accuracy
>However when my battery is over 60-70% the charge speed plummets to 35-40% an hour.
Yup, this is how batteries normally charge, once it gets around 60% it becomes harder for the ions to flow, so it starts trickle-charging to avoid damaging itself.
My guess is no matter what charger you use, speeds will stay roughly the same to what you got, since unless it's using Warp Charge/VOOC, our OP7Pro's will default to regular charging. 15W PD isnt the fastest but it's probably the best you'll get.
I recommend the app called 'Ampere' since it can give you realtime voltage monitoring on how many amps your device is pulling as it charges, useful to check out different cables/wires. Just remember that past 60% almost everything will start to massively slow down.
If the charging pad still charges other phones or the in-use phone after sometime, it could be thermal threshold reached that is commonly reported for wireless charging + wireless AA. There are many threads of this issue in this sub and this is the latest one.
The disconnection may or may not be related to thermal issues. Use an app like Ampere to monitor.

well, there's an easy way to find out! If you have an android (or know someone who does) you can install an app called "ampere" link here
The app will tell you all the stats on the current that's charging your phone. I'd suggest plugging your phone in your house like you normally do and take a screenshot of the charging stats (specifically look for input/charging voltage and amps, displayed as 'mAh')
The usb port on your mini probably has an acceptable voltage, so the amperage is probably the more important number. If it charges at less than 500mAh, then its going to be a slow charge. 1000mAh (1 amp charging) is probably the best you could hope for. But who knows, maybe if your phone has fast charging abilities, the voltage and amperage will line up just right.
If you have an iPhone and your conducting the tests with an android(maybe iphone has a similar app, I'm not sure), take these tests with a grain of salt, different phones accept different power inputs so the stats may be off. For example, my galaxy s6 charges at a higher voltage than most phones, so 1,000mAh for me is fast, but to other phones 1,000mAh is just kinda fast. Either way if the app says the mini usb port is able to charge at/close to 1000mAh on any phone, it'll probably charge fairly quickly on any phone.
Sorry if i overexplained that, or under explained, it was difficult to word that without knowing what phone you have.
Edit: also should be noted that different cords charge better than others (the one that came with your phone will be the fastest, assuming its in good shape), try using a couple different cords to see which is fastest.
Also, You could buy a power converter. It plugs into the cigarette lighter and makes it so you can plug in any normal 2 or 3 prong wall plug (or your countries equivalent) That's what i use, I'm able to get the full fast charging abilities with that, same as if it were plugged into the wall at home.

You mean Ampere.
You'll get the fastest charging from a USB C-to-C cable using a charger that supports USB Power Delivery. I believe the Pixel can charge up to 15w max and the Pixel XL 18w max. Google's official one is a solid choice for $35. Be careful with 3rd party cables/chargers as a lot of early USB C cables/chargers have had tons of issues.
If you don't want to spend the money, you can buy a fast charging USB A wall charger but you'll be capped around 12w. Anker sells a good one cheap for $13.

You should install Ampere to see if the charger or cable has gone bad. It should be close to 800 or more. Ampere
The real question is how many amps your headphones can take and how many amps can the various USB ports actually provide.
According to the standard, USB 2.0 is supposed to provide a minimum of 500 mA (mili-Amps), and USB 3.0 a minimum of 900 mA. They can also offer more, optionally.
For example one of my old PCs and my router provides exactly 500 mA, a slightly less old laptop provides a full amp (1000 mA), and a dedicated USB 2.0 charger provides 2 A (2000 mA). IIRC some desktop PCs now provide 4.2 A.
This isn't an issue because the amount of power is intelligently negotiated.
I.e. if the device only supports 0.5 A that's all it will ask for - and exactly what even the 2 A charger will provide.
Similarly if you plug in a device than can take 2 A into a 0.5 A USB port the latter is all it will be given, it will just charge slower.
All this information should be in the spec sheet for your devices.
But if you don't have that you can test your USB ports with an an app like Ampere to see your current charging rate.
Note: the charge rate displayed will be slightly lower than what the USB port is actually providing because the current consumption of the phone is subtracted. I.e. if the port provides 1000 mA but the phone uses 200 mA to run the screen, processor, etc the app will show 800 mA.
Next, test your headphones.
In Ampere go into the Settings and enable the option to measure all the time, not just when charging. If it works (it's not supported on all phones) it will show a negative value (like -200 mA). Wait for it to stabilize (you might need to kill other apps that occasionally make the power usage spike) and keep that number in mind - that's how much your phone uses on idle with the screen running. Next with an OTG cable (a microUSB/type-C to full size USB adapter) start charging your headphones from your phone. That number will spike, after it stabilizes subtract the phone's draw and the difference is how much the headphones are pulling.
If it only takes 500 mA then it doesn't matter what USB port you use, if it can take more adjust what USB ports you use accordingly.
Note: Use a good phone for the tests, some cheap phones can't charge very fast so even if the USB port can output more the phone will the be the bottleneck and report a low number. Similarly it might not be able to provide a lot of power via the OTG cable, so the power draw of the headphones will be under-reported.
Install Ampere and see what it says. Check your cables, charger and see if any app is using a lot of CPU.
If you have a compatible device: Ampere
~ a) Electric bug zapper with a built-in rechargeable battery, around 20 bucks (the cheaper ones might not be strong enough).
Got it for fun but the whole thing feels super cheap, and the charging cable actually shorted and burned on my second purchase.
But it turns out the zapper itself works really well. It kills the mosquitoes, doesn't get toxic particles in your lungs like the sprays, can be recharged with a smartphone charger (even on the car when travelling), super simple electronics so should easily last 5+ years (and is repairable). The satisfaction when zapping one of them... Never gets old.
~ b) A large mosquito net, for a full size bed, around 15 bucks.
Figured it could help a little even if it's cumbersome and likely to fall into pieces after a year or two - turns out it works flawlessly and has been in perfect condition for 3 years now.
Once you put your tiny hooks on the walls around the room, tie some cord to the end, and add a key ring to each end, you can place/remove the net in less than 10 seconds. Suddenly, you can go to sleep without having to kill every last mosquito - just pop the net, get inside, sleep. A mosquito got inside? Fear not, they're locked in here with you. They can't run, they can't (easily) hide. Kill it, go to sleep. The net saved me dozens of hours of sleep, possibly more than a hundred and still counting.
~ c) A potato peeler (blade perpendicular to the handle). Not a gadget, unlike most of the kitchen stuff you see online - it makes cooking vegetables or peeling fruits so much easier, really turns a hassle into a minor housework. Everywhere I go, if there isn't one I get one at the nearest store and leave it in the drawer. I'm like a potato peeler evangelist.
~ d) A large pack of micro-USB cables (or whatever is your smartphone/tablet charging socket), from Anker/Aukey/uGreen/[insert reliable 3rd party brand].
It might sound stupid to get some if you still have your original one (and a large drawer full of your old ones), but here's the thing:
Very often the cable (male end) of the micro-USB will bend over time, causing the connection to drop and prevent it from raising the charging rate.
Especially if you have micro-USB devices: the standard was completely botched because of some pressures by a certain manufacturer that needed it rapidly for its upcoming line of super-thin models, so it is incredibly more prone to failures (despite its official specification claiming the opposite) and will bend after 6-12 months of average use. That will cause the charging to stop, or to not climb up to its maximum charging speed.
I've donated new cables to random friends/acquaintances more than 10 times already, suddenly they were no longer charging on and off at 10% charging speed, but were reaching 90%-100% of their original charging speed (you can check that with the app Ampere and/or an USB dongle, mine is the Drok one but maybe newer models/brands replaced it).
~ e) A Victorinox pocket swiss knife, around 15 bucks.
Not really sketchy but definitely looks like a cute gadget (Victorinox Classic SD), a gift more than a tool.
Turns out the original manufacturer of the swiss knife knows how to make proper blades: that thing cuts through everything like butter and won't go blunt, and if you're quite demanding regarding the quality of your nail care the tiny scissor will cut perfectly, the cut is sharp and straight, and the tip is super small so can make very precise small cuts. I've used it for minor skin surgery (clearing up wounds, retrieving splinters/cactus spines, etc), it's fantastic.

you could use this to figure it out
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
also good to find bad USB cables that slow the charging
- Install an old version of CheckR.
- Try Ampere or Current Monitor instead.
- Manually...
That said, reading Benson Leung's G+ posts or checking the USB-C Spreadsheet before buying a cable is probably your best bet.
You can use the phone itself to check cables with an app called Ampere. There is an option to show the "Max. possible USB current", which should not be 3000ma. It should be 1500ma, or less, depending on your charger and cable.
There is also an app called CheckR that simply checks the cable for compliance.
It would be very hard for a cable to damage your phone. The danger is that if a non-compliant cable is used with a sub-par charger, the phone might try to draw too much current and burn out the charger, especially if you use it with a computer USB port. I suppose there is a non-zero chance that the burned out charger might somehow put out too much voltage or something and hurt the phone, but this is pretty unlikely.
The cable you linked to from monoprice looks to be non-compliant, as it says it supplies up to 3A, which is definitely more than the spec allows. Also, it's overpriced. I'd check Amazon, where not only can you find nice cables, but you can see if they are compliant from the comments. A Google engineer, Benson Leung, tests most of them, and leaves results in a comment. He also has a list of compliant cables.
EDIT: Addition: Note that compliant cables will not display "charging rapidly" on the phone, and will not charge at full speed. Using a compliant cable, you don't need to worry about damaging anything, and a 1A charger will work, although they are fairly worthless these days, even with iphones, which can charge much faster with a better charger. But they will eventually charge, if the device is not being used.

Have you used ampere and tried to see what the reading is? Fast charging reading should be in the 2500-3000 mA range
From what I've read, it only really slows the charging after 80%.
You can use this app to check the charging rate.
The 1st thing to determine is the amount of energy your phone is using with different apps and services running in the foreground and background. Without doing this 1st, you still could be in a negative power situation and your phone will drain before the aux battery pack dies.
- Download the iphone equivalent of this > https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en and determin how much your phone is draining with differnt services and apps running.
- Acquire an aux power bank with 3,4, or 5A output to stay on par or ahead and provide a charge to the phone running in its max configuration.

Just thought i'd post my experiences with a dying battery.
A while ago I tried driving for Uber and my phone couldn't keep a charge even while plugged in to the car's USB port. I had to look at the map then turn the screen off to get a bit more life out of it. The phone still switched off in the middle of a ride a couple of times.
Things I did to try and conserve battery life:
Installed Ampere
Installed Greenify
Lowered the brightness
Replaced the wallpaper with a black image (took a photo of my wallet)
Switched to Google navigation instead of Uber's
So I ordered a new battery after reading some posts on here. That was over a month ago and it never arrived. The last update on the tracking info was "TO_BE_SENT_ABROAD" so it looks like it never left Germany. I contacted the seller and they offered to either send another or give me refund. Looks like it was Deutsche Post's fault so I hope he can claim for the one that was lost.

Download the app Ampere. It will show you exactly what the charging rate is. Much more accurate than "charging slowly" and "charging rapidly". You will see your charge rate at 480-500 mA for a standard 5W wireless charger.
The Pixel 3 will say "Charging rapidly" even at rates as low as 200mA.
If you use the Pixel Stand, you should see values around 1500mA for actual fast wireless charging.

Since it's from amazon, you can return it if it's not. Make sure you use CheckR to make sure that it is once you get it. I'd recommend that you install Ampere, plug your cable into a wall charger, and make sure the max current is <=what is indicated in the charger, then you can use CheckR to make sure it's compliant.
Keep in mind, CheckR requires you use a USB port from a computer, and it is possible that even with short exposure to that port it could fry it, so if I were you, I'd not take my chances, return it and get one that is for sure supported. I've been using these, they're cheap, sturdy and compliant, and nice length, especially with the 1m/2m pack that I got. Any questions, pm me if you like.
It's an application called Ampere https://play.google.com/store/apps/details?id=com.gombosdev.ampere

This is the Ampere app I'm talking about. I've used it loads of times. It's lightweight and all it does is measure the charging/discharging rate.
You can obviously uninstall it after checking the performance of the OnePlus charger. Although if you're uncomfortable you shouldn't install it, don't worry.
Thanks nevertheless, at least it does charge fast even with a oneplus charger. That's what I wanted to know
I think this is temperate related. Can you test with blowing a fan to your phone while its wirelessly charging to cool it down? then track the temps using these apps?
https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en_US&gl=US

My P6P is only able to wirelessly charges well when its temperature is less than 32C.
Bug report: https://issuetracker.google.com/issues/223539243
My first thought is that it will require less power to charge it while off, and that when on it don't have enough power to charge, only partly supply power.
Have you taken the time to see how fast / slow it charges while off? Is it possible that it is slow charging? Had this issue with a different brand phone after someone (no need to name?) tried to force a micro USB plug into the USB C charging port – probably braking it partly. After a few months it stopped working completely, and with no wireless charging on that phone we were out of options on how to get it charged ... (Haven't bothered having the port replaced due to phone age.)
Suggestion: Download e.g. Ampere app to see how many mA you get when you plug in the charging cable while phone on.
Longer cable means some energy is wasted as heat, a byproduct of the increased resistance. This results in lower amperage. By the time the juice makes it to your phone, you may only be looking at 27 or 28W.
You should be able to see this in action by using the Ampere app.
I'm not recommending it, but you may be able to warp charge through that cable by using a higher-powered brick. This risks overloading the charging circuit, especially if you were to use that brick with a shorter cable.
Keep in mind that the 2m cable is rated for up to 66 watts. Your brick is going to output 30 no matter what.
There are apps ( Ampere , Accubattery , others I'm sure ) that are capable of displaying the current rate of charge, or discharge. Not quite as convenient as glancing at the bottom of the phone when it's plugged in, but still useful.
I could be wrong about this, but I don't think faster charging works when the device is completely powered off.
Have you tried using something like Ampere to see what it says when it's charging?
Also I use this app to test the cable https://play.google.com/store/apps/details?id=com.gombosdev.ampere

I haven't had problems with charging for years, but I still keep the app Ampere on my phone to check if I really am charging properly.
Can you try it and tell us what you see?
Not sure if you're still onboard with this problem, but I use all sorts of chargers (whatever is lying around, really) to charge my F3.
The charger/cable combo that came with the phone is definitely the fastest, with USB-PD C-C chargers being the next best, but not as fast.
You can use this app as a guide to see how many amps your phone is drawing - it's called Ampere, and I've used it for years on Android. Found out which cables of mine sucked in the big, bad micro-USB error
You might be able to tell by installing the Ampere App and checking while your Pixel’s battery is low.
Volts * Amps = Watts
Ampere app. Very simplistic design. Have been using it for a few years. https://play.google.com/store/apps/details?id=com.gombosdev.ampere
the vast majority of chargers can be used on the vast majority of phones. The phone will draw as much power as it can but they are built to not over draw. Meaning you can still use a 60w charger with a 15w phone without doing damage to anything, the phone will only pull the 15w it supports.
> Is there any way to see whats the charging speed of charger on the phone? Maybe an app?
On the phone side you can use something like Ampere to tell you how much you full is pulling in.
Most phones in the power settings will tell you how fast your current charge will take to go to full. If you want to know before buying a charger you don't have a lot of options though.When looking at the charging speed though For android phones this is practically impossible as they're are WAY too many variables to give a reliable answer. Unless the charger manufacturing used your model of phone as their testing solution you can not reliably know how fast.
>need to order the 48V to 5V step down PCB to be able to use it.
Should have come in the kit. GBK has them ($9usd) and loads of them at AliExpress.
1A is the most and if you need more to maintain the charge with ...
- The screen on
- GPS running
- Maps running
- Streaming Bluetooth to headphones
- Phone on 4G or 5G
.... you will have to build a better device. You will need 2A to maintain a charge using your phone under these conditions.
You can find the exact draw your phone has under different demands using this app > https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en&gl=us
Maybe some dirt entered the charging port? Try canned air or a toothpick.
You may install Ampere:
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
and check if it is really charging.
Yeah, you can use Ampere
If your using AA are you not using the cars infotainment screen to interact with it vs your cover display? Also 2.1a is low on the charge scale for heavy use under charging I think. Should look for a 2.4a solution at least. my guess is the car is not even putting out 2.1a you could check with ampere https://play.google.com/store/apps/details?id=com.gombosdev.ampere what it's really getting. At least to rule out variables.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en_US&gl=US
run a test with the app that measures the charging current of the phone.
different specs of fast charging, like QUALCOMM quick charge and oneplus Dash/warp charge are dependant on both the charger and the phone supporting the same fast charging standard, otherwise they default back down to a safe voltage/wattage usually 5 volts at anything under 2 amps.
​
most phones and charges don't usually support more than one fast charge standard. So your 40W charger will never charge your phone at more than 27W which is the max the phone supports, but since they are probably different fast charging standards, it is going to default down to a slower speed.
again the app can show you what charger is best for fast charging.
as for heat, the faster you charge, the more heat is produced. this can damage the battery over time, but charging fast once in a while when you need it is generally OK. slower charging is always recommended when you have the time (like at night).
You can see the charging current with Ampere app. You might need to do some calculations though to get wattage.
You need at least 2A supply for wireless as the output to you phone is somewhere in the .5 to .9A mark. With your screen on, Google Maps running (Satellite receiver) and streaming BT to headphones I doubt you can maintain a charge at that low output level.
You can run a bench test on your phones consumption and wireless chargers capability, to find its usage and charging capability install this > https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en&gl=US
I was facing same issue. Used Ampere to compare charging current. Turned out, my USB C Port wasn't working properly. Try clearing lint first maybe it might work for you.
Have you tried checking the charging/battery details with the "Ampere" app? What does it say?
Make sure you are using good charger capable of supplying high current, at least 2A. Also very long or cheap thin cables will cause voltage drop. Try this app to see the charging current (better be above 1A) https://play.google.com/store/apps/details?id=com.gombosdev.ampere
I personally like Ampere.
Test it using Ampere app: https://play.google.com/store/apps/details?id=com.gombosdev.ampere
It should charge at max speed but the S21 won't say its fast charging, because it isn't. 10,5W charging is just ok speed. You need something that can supply 15w for fast charging or 25w (with PPS) for super fast charging.
So your phone should charge just as fast as your partner, just that your partners phone calls 10W fast while yours doesn't.
You can also download an app to check charging speed, I use Ampere.
You can check the charging speed using Ampere:
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
Ampere
It will show:
- around 300-800mA for normal (slow) wireless charging
- around 2000mA for fast wireless chariging (iirc)
Like the bot says, use Ampere.
Try to meassure the Temperature, to see how hot it really gets.
My favourite Apps for this: https://play.google.com/store/apps/details?id=com.gombosdev.ampere https://play.google.com/store/apps/details?id=com.wered.sensorsmultitool
To be completely certain, I would use an app like Ampere to measure your charging speeds. The app will read your voltage and amperes, then you just multiple the two and divide by 1000 (it measures in mA).
That being said, I believe both of the charging bricks you bought are using Quick Charge 3.0, and if I recall correctly, the S21 line up, along the separately sold official charger, utilises PD for its advertised speeds.
the amps are from using the ampere app
Voltage under load is unknown to me currently
This page gives a comparison of QC modes:
https://www.digitaltrends.com/mobile/how-does-fast-charging-work/
I've added a screenshot to my post.
Ampere is showing me 1240 mA using my LG G8s charger and exactly the same using the charger that comes with the Velvet. Surely QC4+ should be faster?
As far as I know, unless you install a custom ROM there is no way to change those system icons.
But you do have some choices:
- An overlay app that shows the battery info. (not sure if they work on recent Androids)
- An app that shows a notification while you are charging, so instead of looking at the right side for the battery icon, you look to the left to see the icon and confirm it's charging:
- Tasker (very easy to do, but it's not free)
- Ampere (https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en) you will be able to show a notification only while it's charging (but it requires the pro version for this behavior, so it's no free as well)
The main problem with those cheap USB cables (specifically micro-usb) I found out and tested is that the amount of "charge" rate is only as advertised for a few days to 1 week at most.
After this time frame, the "charge" rate just deteriorates and is stuck to a slow and fixed rate. This more so happens to longer cables.
If you want, you can test it yourself by using a ampere measurement app in your phone to measure the amount of power your cable gives out, then compare it to how a normal USB cable should give out.
Also, there is a website that comprehensively reviews powerbanks and chargers of different brands down to its internal circuits that I for one can't find it. The website itself is barebones and is simply a wall of text. Ratings range from "Safe" to "Dangerous".
Use this to see how fast it's charging...
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
Then try every usb cable that you have, to see the surprising difference between them.
Try a higher powered charger, like a 3A one or something.
If you're still not having any joy, then I think a new battery is your last hope.
SS10 is a speed category, and at a quick glance seems to say nothing about power delivery. While in Data mode, it looks like a usb-c type port can support either 1.5 or 3A while charging. It seems like your mobo is only going up to 1.5A (actually at the rate you're losing charge, it seems like it might not even be hitting 1.5A). You could sideload an android app that measures current (I use ampere , but I keep an older version of the app around with non-horrid ads; check apkmirror ?), to see how well your usb port is charging.
As it's a laptop, your options to expand with an alternate usb card might be limited. Perhaps via drivers or bios there might be a configuration option? If you have expansion space, look for a usb card that supports the usb 2.0 or 3.0 power delivery spec; it looks like this can operate with datamode, unlock usb battery charging mode which allows higher than 0.9 A on usb type-A devices.
It won't hurt it, but isn't the best idea.
When using the app Ampere; https://play.google.com/store/apps/details?id=com.gombosdev.ampere
You can see that it will complete go drop 0 mA, so no overcharging.
However...best practice is to keep a battery between 50 and 85%. The Tab S7+ even has an option to prevent the battery from going above 85%. Wondee why they didnt give the Fold 2 this option.
Also...ever noticed how phone come at 50% charge? Thats probably for battery health reasons. So the rule is 50 to 85.
Will try with the stock size battery later on. I know for a fact I used to get 1.8a with that one and the same software. Never bothered to check with the bigger battery. I assumed it took longer because of the higher capacity. I installed AccuBattery and get the exact same readings. I typically get 450ma no matter what. App is this one, it has always worked as expected. https://play.google.com/store/apps/details?id=com.gombosdev.ampere
I prefer the app Ampere, been using it for many years. Here's the link on Play Store:
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
Check your battery working efficiency by using ampere app.
This app will show the battery efficiency after all these years,my 6t gives half a day of full blown usage and almost a day on less usage. At this time my phone's battery has 83% efficiency. If yours is below recommended level,you maybe will have to replace the battery.
You also try this app
I've been seeing the same thing - it looks like Ampere might be accurate though. The numbers in setting are closer to spec at least.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
Check the amperage using Ampere
Grab the "Ampere" app. It'll let you monitor charge rate.
Often, just unplugging and reconnecting gets the phone to smarten up.
Phone batteries are rated in milli amp hours. Which means how many milli amps could it produce in an hour.
However, different phones use different amounts of power and different activities use different amounts of power on the same device.
So reviews will include details like "screen on time" and how long a given phone can play a movie for or browse Web sites for.
And as others have said, battery percentage is what matters day to day for your device.
If you have an android phone, you can use apps like Ampere to see how much current the battery is producing or charging with.
Check the flowing current with Ampere, it's probably a busted cable.
Good luck! My Moto G6+ gives all kinds of trouble with different charger and cable combinations.
Sometimes it only charges properly if I have the USB C in one way or the other, which is not how USB C is supposed to work, I think.
I use the app Ampere to give me real time information about charging speeds.
There are absolutely garbage USB cables floating around. Half of what's sold on Amazon won't support the current needed for fast charging.
My suspicion is the Pixel is just pickier about protecting itself if it senses an issue like higher resistance from a thinner gauge wire so it stops trying to draw current.
Anker is my go-to.
Use the Ampere app to show charging state. Start with a known good charger (either what came with the Pixel, or an over-spec'd Anker multi-port charger) and check which cables are wonky.

If it can sustain 5-10 watts that'll cover heavy usage such as games. You can find out how much energy your phone uses with this app https://play.google.com/store/apps/details?id=com.gombosdev.ampere
You want to look at how much voltage and mA your phone is using. On your powerbank it should state it's output voltage (V) and amps (A)
madVR wont make that much of a difference in power consumption.
yes it works your system a little harder (but also games work the system even harder), but not so much that its gonna cost you more then a few dollars a month
to elaborate on your power statements your computer will only use as much current as it needs. (aka if you have a 300 watt system, and a 500 watt supply, you'll only draw the needed 300 watts (this is over simplified as converting from AC to DC is not perfect and some electricity is always lost as heat))
to further elaborate lets take a somewhat modern android cellphone that came a 5volt 1.5 amp charger. ill use my good ol lg g4 as a example.
5volt is the USB spec so all setups i talk about here will have a 5 volt charger
if i use a 1 amp charger my phone charges really slowly possibly not at all depending on the background apps
if i use the included charger i will charge in about 3-4 hours
but if i use a 3 or higher amp charger the phone will charge in a few hours (this charger is not using any quick charge technology, just a high amperage).
however despite the charger offering 3 or more amps, the phone only took, 2.5 amps as thats its max current (this is observed in certain charge monitor apps, i use ampere when i im seeing if a USB cable is good or not) (heres the charger and USB cable i use)
back to PSUs
the closer you get to its capacity the lower the efficiency (this means it takes power to power the system cause more and more electricity is lost as heat the closer you get to its capicity.
to go slightly further into this issue is when you get to 80% of the supplies output, the efficiency goes drastically lower (hense why 80+ certification is so touted)
Sorry, should have been more clear.
I remember users reporting it changed the UI toggle, fast charging text, etc. but didn't modify the restrictor setting in the root file so the actual amps reaching the device was only changed when the setting was manually toggled.
That's why I suggested doing a dozen teats with something like Ampere.
cc u/Yooooo83
Use thin tipped tweezers, and turn your phone off, scrap the charging port to clear of any hair/lint and dust. Use ampere to check input voltages when charging before and after, give the app a few minutes after boot to give a reliable reading, as app startups and boot sequences will show low input voltage at first. I'd say anything over 1,600mha input is good. MOST IMPORTANTLY TURN OFF THE DEVICE WHEN CLEANING, AND TRY NOT TO RUB THE USB-C CONTACTS A LOT.

It's pretty easy to check. When your battery is running low, preferably under 10%, check the charging speed with the app Ampere. For a short period of time the app should show ~5000 mA when 27W is working. The original charger with 18W only goes up to ~3300 mA. Note that 27W charging speed is only working for a short period of time, after that something internally gets too hot and it will charge at roughly 21W and the higher the battery percentage the slower it gets. However if the app shows more than 3300 mA (e.g. 3600-4100 mA) at any time the 27W Charge Turbo is working with your charger.
I do not know accubattery, but Ampere does this for me.
This thread is probably dead at this point, but I notice it is missing one of my favourite apps.
- Ampere This is a fantastic tool if you have multiple chargers, or if you are using aftermarket cables, as it shows an indication of how much power your device is using, or how fast it is getting recharged. Also it is free with ads, but I guess most people here are running some sort of network limiting app to remove these. (I cannot recommend any of these, but a store search for "firewall" gives a lot of results)
And while I am here
- Relay for reddit My reddit browser of choice. It is best used on a tablet sized screen, but I also prefer it to official app and bacon on my phone. Possibly because of how I am used to the swiping system.
Interesting, this goes against what others are saying here .. would you do me a favor and install Ampere and let me know what rate it charges at?
(Note the phone needs to be discharged enough to charge the fastest, it slows down as it gets towards 100%)
Check to see how your charger/battery is performing https://play.google.com/store/apps/details?id=com.gombosdev.ampere
But as the other dude says this is only worth a certain amount of screwing around when you can get a Wyze Cam for $24 https://www.amazon.com/dp/B076H3SRXG/ref=cm_sw_r_cp_api_i_l1MeEb3X2ZD4T
The OG XL supports 18W charging, and the PD+2 supports 9V/2A. You definitely bought the right charger.
Let's try a couple things. Try the PD+2 with your dad's phone. Is it charging fast or slow or what?
Can you download Ampere and let us know how quickly it's charging? Try this with the dadphone/PD+2 combo, but also with your XL/PD+2.
- Start Ampere and let it run for 30s and then note the current and voltage (roughly)
- Unplug your charger for 30s and note that number
- Try it in airplane mode and don't touch it while it's running.
This will help us establish how much charge is getting to your battery (after the power management IC transforms it from the wall plug), and offset the amount of battery your phone is using. Note that your phone will charge faster the lower the battery percentage.
Right now, we're trying to rule out a bad battery or bad power IC. Based on your findings, we can determine whether it's the XL or the PD+2, or possibly even the cable (seems unlikely to be cable though).

Hey op, it should support QC 3.0 for both powerbank and phone. You can download this app to check the charging speed if you wish: https://play.google.com/store/apps/details?id=com.gombosdev.ampere
This is mine on my mi powerbank gen 3 (which supports QC 3.0 too): https://i.imgur.com/xlPENwU.jpg
Hope that helps.
Try this: Download Ampere (https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en_US) , open the app, and plug the phone in one of the ports. Leave it for about a minute (the initial reading will pop up in 10 seconds) and note down the number of amps (the big number) it shows. Then, do the same with the other port. Whichever port has the higher number is the faster speed port.
Oneplus Dash charge is 5W4A max, which would be 20Watts, but when you install something like Ampere you will se that, unless empty you never hit that, hovers around 4.2V 3.2A most of the time. Source: my 1+6t with dash charger. So i would say they are equall charging speeds, because you wont reach the 18W on the Mi9t either.
Did you get a chance to try it with a USB PD charger? And if you can, can you show the output from this whole charging?
What’s happening is the charger isn’t supplying full voltage. Probably 200mA or less. Generally it’s not charging because your phone is drawing more power than what’s being put in. You can get Ampere to see what your power is when charging. Try unplugging a few times and changing cables if you have to. Takes a few moments before it ramps up the amperage.
Ok, look, there is a power management chip soldered next to the charging port to dynamically adjust the charging rate. You are not always charging at the full speed. This will help you to reduce heat and the level of wear to your battery.
​

What's your battery temperature while charging?
What are the specs of your charging adapter and are you using a quality cable?
Use an app like https://play.google.com/store/apps/details?id=com.gombosdev.ampere to check the actual input amperage.
Charging slows down if your battery temperature reaches >35°C so if that's the case, I'd consider it normal behavior.
Install Ampere. This app show you effective power consumption vs charge performance. If your charging is below 500 mA it could be not enough.

https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en
What kind of time is yours taking? Make sure to be using a mains charger and not a usb port on a computer.
Ampere is a rock star app. Not only shows percentage on a widget, but many other critical variables like temp and discharging milli-amps.
I use this app to determine if I am fast charging or slow charging my Pixel.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
Hi mate! u/ayyy__ had a great suggestion that is probably the answer for your problem.
But there is one thing that you could also try. Part of the problem might be that the cable that you're using doesn't supply enough juice to your phone.
If you have a few different cables, download Ampere and check each cable to see which one supplies the most mAmps. Then use this cable and see if your situation improves.
Good luck mate!
There's an app called Ampere that can show you your actual charge/discharge rates. It is helpful.
You'll want a quality USB cable and a good 2.1 Amp or better charger. An app like Ampere can let you compare what works best if you have multiple chargers and cables. Everything matters. With one 2.1a charger and cable I might get 750mah charging, but with the same charger and another cable I could get 1300mah. With my current cable and charger, I generally get 1600-1800mah and charge between 30% and 40% per hour.
You can download this to check at which rate the phone is charging.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
You have to bear in mind that it will show 200-250 mah less than the maximum rate if the screen is on. And much less if it is near 100%
> It does not swap back and forth continuously on a whim.
I'd recommend downloading Ampere. You might be surprised by the results.
Get an app called Ampere (if you have an Android) but there should be an iOs equivalent and connect your phone with your usb cable. The app will tell you in mAh so 1,000mAh = 1A
The PowerCore outputs up to 4.8 Amps which is PLENTY.
Try this app. Plug the phone in to the power bank and report back what mAh you're getting:
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en
Install that and have a look at how much power it actually provides. The usb spec, depending on which on the connection is built on might deliver so little your phone might be able to drain itself while charging and running maps / music at the same time.
There are usb-c car chargers that will give you more than enough power, but I doubt you are going to get 30 watts out of one.
I would say 1% per minute is fast charging for a 3300 mAh battery. Otherwise mine and the majority of the G6's are faulty. Yours is way under that though since it takes about 150 minutes for you and not 100 minutes, according to your own calculations.
You can try something like this to see what mAh you're getting while charging:
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
Check with Ampere
That app will give you an idea of how fast is the battery charging. Also you can use to see wich cable/charger combinations works best
Using Ampere, it shows my S8 charging at an elevated voltage of 4.35V.
Check out this app. It's called Ampere and gives you real time charging stats. You might also check out your wakelocks, perhaps something is eating your battery alive.
Sure, any Qi wireless charger will work - but it is suspected that only the official Samsung wireless charger will do fast charge.
More testing once the S8 is in more hands will determine which fast chargers will work.
For me, fast Qi charging is nice, but not necessary. My use of Qi charging pads/docks is that the phone sits on them most of the day, keeping the phone topped up. Or at night when I sleep, so being able to fast charge isn't a priority.
Wired chargers - the S8 comes with a fast wall charger, which is nice. If you want to use another brand, I've always got a few lying around the place from various devices, they'll work as well. They probably won't fast charge, but they'll still get the job done.
I wouldn't buy a cheap charger off ebay or wherever, they might not be compliant with regional safety laws. Any charger that came with a device will be fine, and any reputable brand will be fine.
If you have a few chargers at home, and numerous cables, install Ampere and try different chargers with different cables to find out which is the best combination.
You could try the app "ampere". I have never tried it before but this was recommended in android central forums.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
I would use Ampere to test various cables and chargers if you have more available, and see which charges fastest.
I had a "quality" charger and a decent cable but was only getting between 120 and 800mAh charging for some reasons, and it varied a lot.
Turned out, the charger was fine, but the cable was shot. Replacing it with a better one got me charging at like 1850mAh, and now my Shield Charges at 30-35% an hour. Cable and charger combination matters.
Also, just because you have a "good charger" doesn't mean it will work well for the Shield. My phone charges quickly on that same charger and cord, but gets hot, and my vape charges poorly on it, much slower than on another, "weaker" charger, as it's not in-line with the amps it needs.
Can't speak for the Shield controller. I use a third party controller (Ipega PG-9023) because I like to game on the go like it's a portable.
As for charging the tablet, chargers will vary greatly in quality, as will cables. There is an app called Ampere on the play store that will read and record power and fluctuations on charge. It's really useful if you have some chargers and cables available to determine what will work best. I have four different MicroUSB plugs and tons of cables, and I found the 2.1a HP charger I bought for a Cubietruck a while back along with a Monoprice 28/24awg cable performed best (~1800mAh p/hr compared to other ones doing anything from 100maH to 1200mAh depending on cable and charger combo). I have it charging something like 37% battery per hour now, according to Accubattery.
As for keyboard attachments, if it uses standard bluetooth, it will work fine. Alternately, even a USB keyboard should work in theory, if connected via OTG.
As for games, they run great. Many of these ports are full ports. Stuff like GTA: San Andreas, Max Payne, Jade Empire, Kotor, Shovel Knight, etc. They're full ports and run fine. These aren't games that need insane specs in any case, and the Shield is beefy enough. There's also Gamestream, for playing your PC games remotely on the tablet with a controller or touch based virtual mouse and keyboard.
Lastly, as for recommendations, I'd recommend emulation. The tablet is a beast at it, playing everything through Dreamcast and portables through and including PSP without issues.
1st, download Ampere, which if your phone supports reporting charge current it should tell you how fast your battery is charging. Ideally you want >1000ma.
For a more indepth analysis, you can get one of these. I find mine extremely useful.
If its charging slowly with all your chargers and cables though, more than likely you have a dirty or broken data-pin in your micro-usb port so it can only draw the default ~300-400ma. You should look inside it with a magnifying glass and make sure all the metal contacts look ok.
Try running Ampere. It's an application that allows you to monitor the amount of power coming through in real time. By trying an alternative cable whilst monitoring with Ampere, it could narrow down the issue, whether it be the cable on the way out or the power adapter itself.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
Not true. The 5X supports other protocols, such as the Apple protocol for charging at higher currents, which most chargers also support.
You can clearly see this using the app Ampere, and testing cables with a known good cable, or use CheckR to test them.
I have found that sometimes disconnecting/reconnecting the cable will give a different reading. At times, I've seen "Rapid Charging" displayed with my 2.1 Amp Samsung charger and a known good cable.
Sometimes, you can disconnect/reconnect the cable, and it will determine a different rate. I've seen this happen, and sometimes use the app Ampere which reads out the nominal max charging current. It sometimes says 1500 ma max, but actually charges at a higher rate.
I've seen "Charging rapidly" displayed at times using a 2.1 Amp charger and in-spec cables.
That's odd. And yep, mine does indicate rapid charging. Have you ever used Ampere to see what kind of charge rate it's putting out?
Try using Ampere to track if your fast charging or not. Cables definitely play a part. Also fast charging slows down as it nears full charge or when the phone is over heating.
I was pretty surprised when, a week ago, I tested a couple of charging banks we bought. I tried it with several Android phones & tablets running Ampere. The cable made a huge difference, but I haven't been able to get my S4 to charge faster than 1.2A/h.
As far as I can tell (using Ampere,) the S4 maxes out at drawing 1.2 amps/hour no matter what charger I use.
You might also try an extended battery.
Theres an app for android called "ampere" that will tell you your charge speed in real time.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en, use this app it will measure your charge/discharge rate.
Just to add to the other comment, QuickCharge adapters increase the voltage at a relatively low amperage, whereas USB-PD uses 5v up to 3A (15 watts).
Technically, I don't think the Moto Z family or the USB-C TurboPower adapters implement the USB-PD standard, but they seem to be compatible, with the exception of the 5V @ 5.7A (28.5W) mode on the TurboPower 30 charger that comes with the Force. A PD-compliant charger must use 9V or more above 15 watts and doesn't exceed 3A except for the 60-100W range.
You can install an app like Ampere to see how much power you are getting. If the charger is like this one, the best you can hope for is 5V @ 1.67A (8W).
I added a receiver from DISDIM and it says "Charging rapidly" even though it's sitting on an LG WCP-300 puck with a 1A max output. (minus what's lost from inefficiency)
So even if you get a notification that says it's charging rapidly, your best bet is to use an app like Ampere to verify.
this app might be able to estimate it: https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en
Ampere is a useful app to see how much current your phone is drawing while charging or in use that also shows battery temp.
Don't know why Google removed it from ##4636##
Nice looking app, kind of makes https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en_GB look ghetto.
Can always try this app to see how low the current is.
I would download the Ampere app and see what kind of numbers you're getting.
Hey, you can download this app which can let you know the quality of your charger
Download Ampere and post a screenshot.
That could be the problem. Fast charging wears the battery along with wireless charging. https://play.google.com/store/apps/details?id=com.gombosdev.ampere this could tell you the health and the discharge rate of your battery. Around -600 discharge is normal. Also check in ez disabler (if you have it) and disable all the gear vr crap icluding any oculus vr packages. Also check developer options and see what is running in the background.
It was pretty obvious from the "time till fully charged" in Android's battery stats that it wasn't charging correctly, but I've decided to test it properly by using this app. It's the best we can do without hooking up a multimeter. I tested a couple of cables and chargers that I know the rating of and it appears to be pretty much on the money.
When using just the Dash cable and power adapter I get 3340mA. When I throw the USB 3.0 extension cable into the mix it drops to around 1400mA. That ties up with what the battery stats were telling me.
Try this (first search hit, not sure if it works for OP3): https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en
My Nexus 7 was charging really slowly for a long time and then the battery started draining even when the tablet was plugged in. I checked the amperage coming from the charger (original) by using an app like this one - Ampere (I don't remember exactly which one but ampere should work). It showed ~50 mA while charging and a negative value the moment I started tapping around. After a couple of weeks it stopped charging entirely.
So, the first thing you should do is check the amperage. It will probably show less than 400 mA. If it does, try another usb cable / charger. The problem could be the mini-usb port on the tablet in which case it may need changing. If all else fails you can try reseating the battery.
However, I fixed mine by following the instructions from this video https://www.youtube.com/watch?v=x8u8xSnfCOA. The battery was totally drained and it wouldn't turn on so I had nothing to lose really. After charging it externally for an hour it started up with 2% and I got it to a 100 with the normal charger in 2-3 hours (took me 8 hours before).
In the following 5-6 days my Nexus 7 was just like when I first bought it. I sold it after that (a month ago) and the new owner hasn't reported any problems.
I think Qualcomm's "Quick Charge" protocol requires a handshake with the device to allow it to start charging rapidly. The Pixel doesn't do that. It's using the USB-PD standard. I think your charger is simply not getting the response it's looking for from the Pixel and is reverting to 5V/2A. I would download the Ampere app to double check though.
> just stopped indicating it was charging
This happens all the time with the charger in my bedroom. The status bar says it's on battery power, but the percentage still goes up, and apps like Ampere say the phone is charging. It seems to charge at a normal rate, too.
Not sure why it only seems to happen with this particular charger. I've used this same cable and AC adapter on several previous phones. I guess it could have to do with the micro USB to type C adapter I'm using, but I use the same brand of adapter on a couple other chargers with no trouble.
You could monitor the input voltage using something like ampere. Normal should be 5amp and chick is like 7.2 or something https://play.google.com/store/apps/details?id=com.gombosdev.ampere
The android app Ampere seems to be the go to. I haven't actually tested the "smart" port on this power bank yet (Ravpower 20100mah - I opted for it over the Anker due to the 2 way 5v3a Type C port) but in theory it shouldn't go beyond 2.4a. I'll have to wait until the battery is below 90% now since it seems to limit it to ~1000mah.
Wouldn't Ampere do that?
First check how much output your charger can give. Should say something like Output: 2.0 A
Then you could try Ampere and see how much amps your phone is getting from the charger.
It could be a faulty cable or a faulty charger.
How do you know what it's performing at?
It all depends on what your phone supports, quality of the cable, level of the battery being charged, etc.
You can measure using this app
Or how about if you are well known and can be a reliable source every weekend, you just bring an inverter. Customers with speed chargers can bring their charger. You'll have to charge them more, based on amperage drawn (can vary), and their chargers typically won't work for other phones (if other customers start asking about it).
There's also an app (Ampere) that will tell you how fast your battery is draining or charging. The free version doesn't allow you to see the data in the notification bar, so they'd have to measure it and get an average over 20-30 seconds, then go back to Pokemon.
Get an app called Ampere and plug it in, tell me what current it is charging at.
It could be your USB cable too. Seriously. I found several cheaper cables I had bought just couldn't carry a proper current using Ampere on my Nexus 6. Using a couple of different actual OEM cables from a few different devices (my Fossil Q Founder, Moto X 2013, and Shield Tab K1), I found they carried a lot more current (up to 4x as much) when compared to cheaper cables, such as ones I had snagged from checkout lanes for a few bucks.
Note: I couldn't compare cables for the 5X since I only have two, the OEM Type-C cable and a Type-A-to-Type-C cable, which when used with my Anker batter, supplies sufficient power for charging.
Now, if you're using one of the OEM cables for the 6P with this charger, then it would more than likely be the charger simply not being able to provide enough power.
Check out Ampere on the play store and see what it's outputting.
Download the Ampere app and it shows you how many mA your phone is getting from your charger. The phone should be close to 3000mA (usb-c does 5V/3A {3A=3000mA}) if it's going full speed. If it's not then something is wrong.
Download Ampere and see what your charge rate is.
I use an app called Ampere - it will show both charging and discharging current, as reported by the phone.
Check the app Ampere. It will show the rate of charging/discharging.
This is what I used to think, but when it seemed that it was doing it in the 40s it changed my mind.
This makes sense though, maybe I could start watching power use on Ampeer
Check out this app to see if your cable is the issue. The only problem is you'll need another cable to compare too.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
The IFTTT notification wouldn't be instantaneous, you might want to look into an app that could give you a system notification when the phone is fully charged and get that notification mirrored to your Pebble.
I currently use Ampere for that.
Hmm, that is unusual. Slightly off-topic, have you tried charging with a different charger AND USB cable?
I've had phones that degraded in battery capacity over the years, but not in charging time.
Oh and I suggest using something that lets you measure battery charge/discharge, such as Ampere https://play.google.com/store/apps/details?id=com.gombosdev.ampere
If you're android there's an app for that. It's great for seeing which of your old cables isn't any good too.
Just don't stress about overloading the phone. The phone negotiates increases amperage. Just get the biggest, high power bank you're comfortable carrying and paying for.
You can use Ampere to check the current. Usually a computer's USB outputs at 500mA, but some PCs have ports that are meant for charging and output more current. Also, USB ports always output 5V.
Link to Ampere: https://play.google.com/store/apps/details?id=com.gombosdev.ampere
TLDR: I'm verbose and comprehensive. Read the bolded text if you don't care for either (or for evidence).
^Preface: ^mA ^= ^milliampere. ^Amps ^are ^a ^measurement ^of ^current, ^the ^rate ^of ^electrons ^flowing. ^Think ^of ^it ^like ^gallons ^per ^minute ^flowing ^out ^of ^a ^pool.
I just checked my phone using Ampere. While connected to WiFi, it settled at +380mA. In airplane mode and it settled +510mA. Off the charger, in use, it settled at -300mA used.
Keep in mind that these currents are drawn while the phone is awake. That's a limitation of Ampere. It only measures when the display is on and the app is open. We cannot reasonably infer that the device charges ~130mA slower in airplane mode. Obviously, the delta should be much lower. However, let's use that figure for the sake of this argument.
I used a very slow charger rated 700mA. I have faster chargers but I have a long day tomorrow and slow-charging promotes greater charge saturation. I can talk about that later if anyone is interested.
The delta between the highest charge current and the uncharged current is 810mA. 130/810 ≈ 16%. From this terribly unscientific and fundamentally flawed thought experiement, I begrudgingly say it's possible that a device could possibly take 16% more time to charge while awake and not on airplane mode. If the phone is asleep, that delta should be much smaller between the airplane mode/normal connectivity.
However, we can reasonable assume that there's a considerable difference between charging your device while it's off versus charging it while it's actively being used. In most cases where you need the most charge possible in a short period of time, it's recommended that you turn your device off. Why put it in airplane mode if you can't receive messages/call anyway. Actively using it will decrease rate the battery can charge. Note that since the current drawn during use is independent, the difference becomes much smaller if you have a faster charger. Using a non-QC2.0 5V/2A charger yielded get ~2400mA delivered, so the 130mA delta would only slow charging time by 5% to 6% in our thought experiment.
More thoughts: The phone used also has a significant influence on the data. My Nexus 6 has a large display that draw a lot of power. Additionally, I use a modified kernel with a hotplug and governor that aggressively powers down as many cores as possible and keep cores as high as possible when active. You also should keep in mind that an actively used phone will generate more heat than a phone turned off. The power controller on phones will limit charge rate based on on battery temperature, so actively using the phone may generate conditions that cause slower overall current. Further, the power controller may limit the charge rate based on the current battery level. Finally, devices that use Quick Charge can also vary voltage, so current may not be an adequate metric.
I am not sure if a new battery would help, because when your phone does barely boot when being plugged in, it seems more that either your charger or the cable are making problems. It seems strange though that your pc does not recognize your phone when being plugged in. So it could also be that your phone is having troubles receiving power...
If you think your battery lasts long enough to install an app you could try one of these: Ampere or OPO charging current to measure your charging/discharging current.
The wall-charger you posted is a quick-charger and I am not sure if the OPO is compatible with this kind of technology or if this charger may have damaged something. Because afaik the OPO does not support quick charge, but charges fast anyway with the stock charger&cable...
Use an app like this to monitor the charging for different cables and find some good ones.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en_GB
That's really weird then, have you tried using Ampere to see if your phone is actually receiving the correct amperage?
I'm thinking it may just be a bunk battery :(
Try https://play.google.com/store/apps/details?id=com.gombosdev.ampere and screenshot your stats while charging.
Have you used Ampere to check that it still sees the charger being connected? This is starting to sound like a bug in the ROM to me
Get the ampere app (https://play.google.com/store/apps/details?id=com.gombosdev.ampere) and it will tell you the max charge rate for that cable (as determined by a resistor in the cable).
1A (5W) is enough for the phone to say 'charging', the phone wont say 'charging rapidly' until around 2A (10W).
Try using the Ampere app to check the charging rate of the cable.
I'm not using a stock charger and I haven't had any issues. You can try an app like Ampere and see if your charger is delivering enough power.
Have you used something like Ampere on your device while wirelessly charging?
Make note of how much power the device is drawing, then move it some.
My Nexus devices will keep charging, even if not perfectly centered. But they don't charge as fast as they could if they were centered.
I'd suggest installing Ampere and looking at the actual charge you're getting.
One thing that I found: there can be a big difference between cables, not just the actual blocks. I don't really know what it is about different cables that make such a big difference, because I found a cheaper, no-name cable providing better charges than an OEM cable that felt like it was a higher quality... so I think the best thing you can do is use this app and see if you can at least maximize the charge you're getting.
I'd also highly recommend investing in a QC charger. You can get them for a reasonable price on Amazon and are undoubtedly worthwhile.
Maybe try an app like Ampere - It displays the current charge you are getting to the phone. Can swap out cable/port and see where the issue is?
https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en
What does Ampere say you're charging at?
Thanks for the feedback.
I found your app! <strong>Ampere</strong>
:( thanks for trying!
Guess I will need to use the Ampere app u/itsnotjustabell mentioned.
Install an app like Ampere and note the charging current and the temperature. I'm guessing your phone is hot enough to slow down the charge rate.
Pretty sure the voltage is going to be wrong. I would check with the Ampere App to see that these are giving out the correct voltage. Better be safe than sorry as this might damage the phone in the long run.
Could you check the amperage the cable is providing your nexus 6p? I'm trying to figure out if its worth buying. You can do it by using Ampere. If its providing similar amperage as the stock google cable, its a quality cable. Thanks
Thanks for the info. Is the cable quality good? Have you tested in Ampere when connected to a charger to see if the cable is providing amperage close to the OEM cable?
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
https://play.google.com/store/apps/details?id=com.ericjohnson.currentmonitor
I've had this problem as well, the notification says it's fast charging but is it charging very slowly, more like cable charging speed, and the micro USB end of the wire is also very hot during charge, so much so that it started having burnt marks. The problem was solved when I went to the Samsung service center and changed the charging cable. So faulty cable might be your problem.
Also, you can check if your phone is fast charging or not by using Ampere. Normally for fast charge, the current will be around 1000mA (for me at least).
I used this app to check if the charger still gets to 1000 mah: https://play.google.com/store/apps/details?id=com.gombosdev.ampere
The issue is fast charging is registered if it's above a certain amperage... but what really need to know is if it actually outputs 3A. If it's 2.4A for example, it will register as fast charging but won't be charging at maximum capacity of 3A. If you wait for the phone to drop below 20% and then try it again while measuring the amperage using this app: https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en
Then we can all know for sure if it actually is outputting 3A. I've been following these discussions on this very adapter for weeks now and nobody ends up getting back to the group to respond. I actually bought the same car charger but don't have the phone for another week or so.
Yeah I was talking more about using one of the various apps from the market to get an idea of what's actually being drawn. That and you know, just timing it, it'll be pretty clear if it's charging as fast as the official charger.
I spelt it wrong but here:
https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en
Consider grabbing the freebie ampere app. It'll tell you whether your charger's giving you any juice at all.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
Then go through the motions of seeing what's been using your power. Maybe something will stick out?
Is it getting hot? Its normal for it to get a bit warm when charging, I mean is it getting hotter than normal?
You can also try installing an app like Ampere to see if it's drawing more current than others have reported online.
No indicator - this app is neat though and will tell you (if you know how to read it.) It generally shows me around 1520mA of current with a regular charger and 1960mA with a quick charger.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en
Try out thisapp if you weren't planning on it already. It might make the tests a little easier to conduct as well as being more accurate.
Edit: thanks for the gold :)
I've been using this app ( https://play.google.com/store/apps/details?id=com.gombosdev.ampere ) to find what charger and cable Combo I have works the best. It has worked great for me. On a side note the HTC charger that comes with the HTC one m9 is not a Qualcomm quick charge 2.0. Good thing is that they cheap and worth the money.
use https://play.google.com/store/apps/details?id=com.gombosdev.ampere you will be suprised how the same charger behaves connected to diff power sources.
i am dealing with same issue trying to figurr out is it battery charger or the USB port
Yeah I'm honestly not sure if this applies to all, but if it does then I guess your sitting on a gold mine then. Here's how to check: download Ampere from the Google Play store and let it run. Now typically your phone will use around 300mA if the screen is on and the phone is basically at idle. So if they are charging at 1.8A, you should see a reading of about 1500mA or slightly more (up to 1800mA max but realistically up to 1650mA or so).
Try removing and reinserting the charging cable. And rebooting if it's still happening.
And maybe get a chunky USB cable and a decent 1.2-2A power adapter.
Ampere is a free app that shows you the charger speed, which varies with power adapter and cable.
Thanks for this, I was looking for an adapter that had a signal on the actual unit itself that displayed when quick charging was supposedly working. I may order this in the future! Out of curiosity, could you run the Ampere tests and tell everyone what you're getting when the light is green? https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en
Haha. Girth. There's probably no easy way to test it. Could test maximum amperage that will flow, but it would be easier to plug it in and see what happens. I was shown this app ( https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en) which would help you find a high current cable.
Well, I honestly have no clue. Try playing around with Ampere and see what it's doing. Otherwise you should contact Sony for warranty.
Funny thing is that 500mAh from a computers USB port is standard. Now you can install a kernel and that will allow "fast charge" but only after that should you be getting 1A from a USB 2.0 port. So far, I have only tested 1 USB 3.0 port and it gave me 1A, but I also had fast charge enabled. I'd say this notice in increased time spent charging must either be from your previously not being totally stock (?) or its just in your head because it's performing as intended. In the meantime, download an app that'll tell you what your power input is such as Ampere or Gsam and that'll take out the guesswork.
I use Ampere, but I think System Monitor can actually make a graph of it developing.
You could check that with Ampere.
*First, you have. Please, for the love of all that is right in the world, try harder.
Fast charging is great at 2 amps or higher. It is still much faster than any other phone I have used regardless. You can usually read the amperage that your charger provides via the unreadable information from the plastic mold and/or sticker. Alternatively, you can try an app to read what the phone thinks it is getting. I use https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en .
You can use S Note with Evernote-- which is great. I use it for meeting notes and doodles either for demostration purposes or diagramming ideas for myself. As for creating art... I don't have time for that crap, the tools as they are meet my needs and I haven't gone looking. (Meets my needs, unlike the calculator app and the TV Guide wannabe infrared remote control app-- both replaced because they try to do too much from my perspective. I don't have cable TV, why make me choose a cable provider? Does my calculator need to talk?)
For my car I use a Belkin In Car Tunecast 6 Universal FM Transmitter. This one has a setting with a 'speech bubble' which looks and sounds to be optimized for spoken word. It plugs into my phone's headphone socket. I've tried other FM transmitters but they are not 'powerful' enough; this is my second Belkin and both have worked well (the first one I trashed when the wires near the cigar lighter plug got pulled out.
I also need a generic ground loop isolator, otherwise I get noise when I'm charging the phone (or another device) on the car's other cigar lighter socket. I wanted one with male and female 3.5mm jacks, which are harder to find; most are male-to-male (making them easy to use for input as well as output). But I've since realised that a make-to-female adapter would work fine. I need to replace it because of a broken wire near the male socket (where it plugs into the phone so gets flexed a lot) but, while I get a 'lost channel' that is noticeable for music, it sounds not too bad with spoken word.
So yeah, using wires are a pain and I'd really like a bluetooth equivalent by Belkin but I'm on a 'family budget'!
While my Belkin has a USB socket for device charging, IIRC it doesn't give maximum charge. So I have a 1200mah battery for the other cigar socket and a charge-only cable (can't be used for data sync) so that my phone actually receives 1200mah of charge, as verified using the Ampere Android app.
I use the Llama Android app to detect when my phone is charging and has something plugged into the headphone socket (i.e. I've just engaged the car's ignition with the phone plugged in) and it sets a variable (which I can also set manually). The variable being set kicks off various settings, including boosting the media volume to maximum, starting hands-free/driving mode and starting Smart AudioBook Player.
I'm not too bothered about headphones (and still on a budget!). I have JVC Marshmallow in-ear headphone, mainly because I love the squishy ear buds that give a nice tight fit (great bass and doesn't annoy folks on the bus) but also because I can get them replaced under guarantee when (not if) I get a snapped wire (causing loss of one channel) at the supermarket near where I work. At home and work I have two sets of vintage 1990s Sennheiser HD 480 II: the 'standard' broadcast studio headphone used by the BBC, open back, small foam earpad. Still doing a great job after all these years.
Try various cords and chargers. There is an app called Ampere that shows the amperage you phone is charging at. You'd be surprised how much difference there can be from one cord to the next. Longer cords tend to be slower.
There are "fast charge" cords that I have tested and they work very well. Also, as /u/exoriare mentioned, you can add a Qi receiver to you phone and use a Qi charger to charge your phone wirelessly. Mine charges at a higher rate wirelessly. I think the USB port maxes out at 1.2A, but the Qi goes up to 1.9A. I tested many different cords and chargers.
Have you tried to download Ampere? It will tell you how much power your phone is recieving so you can check if it is a cable/outlet problem.

Description Did you ever felt, that one Charger/USB cable set charges your device really fast and the other not? Now, you can prove this with Ampere.
Measure the charging and discharging current of your battery.
The app works on Android 4.0.3+ devices. Not every device is supported because there are devices which lacks an appropriate measurement chip (or the interface) and they can not be supported at all. Please read the list of not supported phones at the end of the description.
The app is not meant to be mA accurate. It is only good for evaluate which Charger/USB cable combo is working the best for you on the same device.
Start the app and wait ca. 10 seconds ("measuring" is on the display). After this time, the charging or discharging current will be shown.
The current depends on many things: - Charger (USB/AC/Wireless) - USB cable - Phone type - Current tasks running - Display brightness - WiFi state - GPS state
Have you tried Ampere? https://play.google.com/store/apps/details?id=com.gombosdev.ampere
At least you'd have more of an idea of what's going on.
It could also be a fried USB cable.
is battery life bad?
Maybe try this app
Ampere

If you arent getting over 1000mA, something is wrong with the charger or the cable.
Ampere is the only app to the best of my knowledge that tells you (if you open it up and look- no notification). Otherwise, I don't know of any apps that offer notifications.
Going along the lines of the wireless charger, install Ampere on your phone and check out the kind of charge different cables/usb cubes provide and find one that charges at a slow rate.
Fail Link bot.
Could it be a problem with your charger? Try out Ampere to see what amperage you're charging at. I know that a similar thing happened to me when I had OK Google detection on during charging & was charging from USB at around 300mA.

I've never used greenify, no idea how it works, but I'd assume it just closes apps that are not in use in order to save battery. That said, I don't know what specifically is killing your battery. You might check out Ampere and check your battery's health.
My only other guess is that something is running in the background without your or greenifys knowledge and is eating up battery. Note: it could even be greenify. I've heard that apps like that can use a significant amount of battery. Just things to look into.
You could check what Ampere says, but if you are using different cables in all those situations it's got to be the phone.

Also, try a battery calibration by turning it off, plugging it into the charger that came with it, and leaving it like that (turned off) overnight even if it shows its charged.
I would say Ampere. It's a 4.4 rating. It let's you check out your charging speeds with different chargers. Let you know when a charger is a rapid charger or normal. Also let's you see your discharging speeds. Really useful at throwing away crappy chargers from amazon that you have laying around.

How about testing it yourself?
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
honestly it probably would, but it's only pushing 500mA with the good cable, when I'm using the cable it came with it only pushes 100-250mA, and that charges the device painfully slow. (checked these numbers with the app "Ampere"
Edit: Wow, someone didn't like that answer. Seriously, with the USB cable it came with, it took a really long time to charge.
