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.
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.
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.
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 ([link]).
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.
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 :)
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
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.
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.
The results of an experiment i did a while ago revealed that:
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 :)
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 [link]
it is just one more type of RAM cleaner app
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: [link]
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.
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.
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. [link]
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.
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.
Use this to test your cable and wall socket while the phone is on.
- Ampere – Android Apps on Google Play - [link]
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.
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.
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.
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
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 ([link]) 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.
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 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.
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.
Try a different micro USB cable.
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.
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.
Keep in mind that it could also be the cable you're using with the charger.
> 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
I'll answer the last question.
Of course. If you're curious about this stuff, you can get this app. [link]
Even better would be to get an external tester.
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.
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.
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.
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 :)
Apps like Ampere or Aida64 can give you some info.
Well, you could use Ampere and measure the charging current, I suppose anything above 2A would mean super charging.
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.
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."
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.
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).
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.
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.
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).
With Ampere you can "Measure the charging and discharging current of your battery". Maybe this helps you when trying different chargers for testing...
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?
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
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.
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.
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%
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.
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: [link]
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.
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.
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.
Stock Android doesn't show "charging rapidly".
Try this app [link]
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.
/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.
Try using Ampere to see what the charge current is: [link]
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: [link]
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.
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 ( [link] )
Edit: added link
Install Ampere from the play store - [link]
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.
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.
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 [link] 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)
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'.
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 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.
Get Ampere, it will tell you exactly how slow it is charging.
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.
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.
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.
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.
Download Ampere and see what its charging at. Youll probably have to activate the "old measurement method" to get it to read.
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.
On average it should only take from 2.5 to 3 Hours to charge fully on standard charger.
Check your cables/charger with Ampere App.
What kind of time is yours taking? Make sure to be using a mains charger and not a usb port on a computer.
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.
According to this post, only the Pixel stand can fast charge at 10W. All others will regular charge at 5W.
Download Ampere from the Play Store and see just how fast your Pixel 3 XL is wirelessly charging.
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.
*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 [link] .
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?)
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've been using this app ( [link] ) 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.
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.
Get the ampere app ([link]) 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).
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
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...
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.
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.
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 [link]. 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.
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.
That could be the problem. Fast charging wears the battery along with wireless charging. [link] 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.
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.
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.
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.
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:
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.
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.
is battery life bad?
Maybe try this app
If you arent getting over 1000mA, something is wrong with the charger or the cable.
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 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.
