My wife insists on using her phone in bed at full brightness + 150 million percent, which looks like when they open the ark in the Raiders of the Lost Ark...
As others have stated, it depends on the type of screen.
Traditionally laptops have used LCD screens that show a picture (without giving any light/brightness to it) and CCFL (Cold Cathode Fluorescent Lighting) to give it brightness. However, those lights go around the edge of the LCD and will light up the whole panel, so power consumption would be the same whether the screen was showing dark or light content.
LED-LCD screens work the same way, but use LEDs as the backlight instead of CCFLs. LEDs use less power than CCFLs, but LED-LCDs still uses the same power regardless of content.
OLED screens, which are mostly found in phones or TVs, use organic compounds that light up when electricity is applied to them as their pixels on the screen. They usually use a red, green, and blue subpixel for each normal pixel. A black screen would tell all three subpixel to be off, a red screen would tell the red to be on while blue and green are off, etc. White is made by turning all three pixels on. Since these only turn on when electricity is applied, having black pixels means no power is being used by those pixels, reducing power consumption.
Since OLED screens are usually on phones, there are lots of apps that take advantage of this. Apps like Screen Filter will lower the brightness of all pixels on the screen, meaning less power has to go to the pixels. Other apps, like the now-deleted Pixel Battery Saver, would put aa black "mesh" or "grid" overlay on your screen's content, meaning many of the pixels would be black, thereby saving power.
Agreed. I used to use the screen filter app which lets you go even darker ([link]), but I haven't felt the need w/ my 5X. It's not as dark as I'd like, but dark enough.
The best was my galaxy nexus. AMOLED + screen filter = amazing. In the parts of the screen where it's black, you can't even tell it's on! Amazing.
Worst was the LG G3 I just had previous to the 5X. Not just an LCD with bleed, it also had poor viewing angles. So reading close at night gave a weird effect (since each eye sees slightly different colors due to the angle), not pleasant.
I do still wish we had amoled - just the nicest screen tech I've used. But that said, the 5X comes very close and I like it.
Also, 1080p FTW. I hated the 1440p screen, such a pain.
Screen dimming app? The minimum brightness via Android settings is still too bright.
I've used Screen Filter forever. Wondering if anything better.
Ha, I actually was just looking for one tonight while reading a bit in bed. The one I ended up with was screen filter. I'm assuming you are only wanting it dimmed, not tinted like the Twilight app. No permissions, and I haven't noticed any ads even. I don't think it's too hard to find one without permissions though if you want to look at others.
Neither Bluelight nor this filter I also use (when dark just isn't dark enough) have any effect on those buttons. It's ~~infuriating~~ irritating.
On Android there multiple apps, I use one called Screen Filter. [link]
You can set how dark you want it to go, I usually turn it on when I go to the movies before it starts so if I need to reply to something it doesn't bother anyone else. Works great at night too
You can disable it using the "screen filter" app on the playstore
Turn the filter brightness off and tick "tenable softkey backlight"
It creates a widget on your home screen, so if you renamed it using nova launcher to "Turn off backlight keys" you have a permanent solution there :)
I used Screen Filter years ago on a Android that was waaay too bright even at it's minimum and it worked well. They have updated since then, but it looks exactly the same. But if it works, who cares what the settings looks like?
That's not true. Get the app screen filter and there's an option to enable softkey backlight. Uncheck the box, keep brightness at 100%. Tada
Edit: ok I misunderstood. Yes the physical keys will still be there but without the backlights they're much less noticeable
Too bright in the dark: [link]
Screen Filter (or any similar app) will allow you to darken the screen as dark as you want.
I used Screen Filter + Kindle app to get my phone dark enough to comfortable read in the dark without ruining night vision.
Aaaaah please! Background applications are closing after 30 seconds, and it's a pain! (And I'm talking about really simple applications, like Screen Filter)
Wow. Awesome resources.
Free alternative to Darker that I use: [link]
Just a warning, don't get curious like me and adjust it to the point where it is so dark you can't see your screen. That was a mistake...
IIRC, Most devices only allow the most optimized brightness settings. When they are tested, they look at what is the lowest you can see it during the daytime and nighttime, and what's the brightest at daytime and nighttime without too much eye strain. If you're running android, you can install an app which can lower your brightness even more
Edit: for those interested in lowering their screen more and are using android devices, here is a link to an app on the Google play store
commonly achieved by displaying a black image over all other apps with a transparency value. my personal favorite is screenfilter (com.haxor)
I used to use https://play.google.com/store/apps/details?id=com.haxor , but it has been abandoned and I don't know how it behaves on modern Androids... but you could try some of these.
I remember some phones (or roms) let you move a slider for each RGB color, and you could completely remove the blue color. Unfortunately I don't remember in which ROM I saw that, but someone might. :P
I've tried Night Mode, but it changes the tint more yellow than black. I ended up using Screen Filter since it seems to have low overhead and no required permissions. Only the notification panel remains undimmed, which is actually kinda helpful.
On Android use sceen filter. It's a super basic app and in puts a semi transparent layer of black over your screen. Making everything a bit darker.
In a dark room the lowest brightness is always too bright for me.
This is the app [link]
There are others, but this one I like the most because it's a so simple and I have been using it since my note2..
Screen Filter should be some kind of default app. I used to use it when I was reading ebooks at night next to my girlfriend, if you set it low enough it's just like reading paper in the dark.
Screen Filter for Android.
It's a screen dimming app without all the sepia sliders it timers or whatnot. Tap to dim the screen. Tap the notification to adjust the intensity. It does its job so simply and doesn't muddy colors up too much. Works great when the lowest brightness is still too bright in bed. I use it in tandem with Google nightlight feature.
I use Screen Filter. No ads, nothing to buy, just darkens the screen to however dark you want it, you can even make it nearly invisible if you want with it. It also applies to every app and the drop down menu.
intense social anxiety and a sleep disorder led to me sleeping more during the day and staying up at night, for many years. i started to track my sleep, so that i was more aware of how much i sleep and when. i decided to switch my studies from on-campus to online which decreased my social anxiety enough to the point where i wanted to try and be awake during the day, i wasn't constantly trying to avoid people.
i figured out the best times for me to sleep (a gradual shift from where it was to where i wanted) and then i worked on having a good routine and good sleep hygiene. my routine includes giving myself time on my phone in bed which is usually something people say is a bad idea but i use screen filter which keeps the screen really dim so it doesn't keep we awake. i also listen to a lot of guided meditations and visualisations that distract me from my thoughts and the worry that i won't be able to sleep.
I think a steady sleep pattern can regulate eating a little bit and having a routine with meals/food is important but can only really happen if sleep is regular first.
I use an app called screen filter, made by haxor industries [link]
I think it's great, you can adjust what brightness you want, down to completely black. Just be careful you don't set it too low.
I liked vivid, but I use basic for best color accuracy since I sometimes edit pictures on my phone, and using vivid just makes that impossible.
If I really need to have my screen darkened I use this app.
Amoled screens tend to have pretty high minimum brightness, maybe he is affected.
Also, if you are an android user, there is this nifty app, to tone down the bright minimum brightness lower
I know what you mean, I was worried about it a little myself. I installed this app and turn it on at night when I'm in my pitch black room, remedies the problem perfectly: [link]
On Android devices you could download apps that lower your screen brighness even more, such as Screen Filter or Bluelight in which some cases even changes the color to hurt your eyes less. For IPhones however, I am not familiar with. I also believe that the different minimal levels of brightness depend on the technology that goes into the screen.
I noticed the same thing too. Sometimes the screen is too bright when at the lowest settings (especially when trying to read about ebook at night). But as the other poster said, it would be difficult to turn it back up to full brightness, because you can't really see the screen without a backlight.
One solution I use (on Android) to dim the screen even more is a free app called Screen Filter. This essentially puts a black filter over the screen and you can adjust how strong you want the filter. Works very well in dark places.
This might be useful. Certainly easier to use than a physical filter. It's so weird to watch videos on my phone with the brightness turned down too low to activate cones. It's like watching it with a strange alien and colorless sense.
Also, Screen Filter for Android. Not automatic but it's tiny, ad-free and lets you turn brightness down way past what the standard brightness setting will allow.
Screen Filter to quickly turn brightness down to a level lower than phones go (done via translucent layover), because phones are too damn bright in the middle of the night!
Pro tip: set swipe-up on Nova Prime Launcher to trigger same effect (just open the app on action).
I'll check but FYI I just reinstalled without importing any apps from my old phone and this same issue still occurs
Edit: Screen Filter is in my app collection (but not installed the last go around)
On Android 5.0 on the MotoX 2014 the brightness was perfectly dimed at night, with 5.1 the brightness is to high at night so I downloaded a app called Screenfilter, it's free and doesn't track shit or want any user or wifi information here's a link: [link]
I like this widget Screen Filter for toggling a pre-determined filter setting. My S6 lowest brightness is still too bright while reading in bed, so I click this widget for an immediate darkness. Very light app for just 1 simple purpose...
Screen filter gives you the ability to turn the brightness of your screen really low. Great for if you go to movies but still need to check your messages / emails ( I'm a sysadmin) or in bed at night and the screen might annoy your partner trying to sleep.
The description of the app ([link]) is quite honest:
> Applies a shade that acts as a dimmer to ensure your eyes don't hurt. Far more powerful than Android's built-in brightness setting. Great for low-light gaming, web browsing, and eBook reading. It even saves battery life for AMOLED displays!
The technical reason for the difference is, putting it as simple as I can (you can google hundreds of articles on this) :
These apps turn some of the pixels "off"/"black", giving a dimmer image.
In an LCD, turning pixels off is impossible, you can only put "black" in them. The backlight is just masked for those.
In an AMOLED, think of each pixel as an individual LED (well... Close enough): you can shut them off for a perfect "black" - doesn't emit light. So, if you have more black pixels, less power is needed.
LCD backlight is what consumes your battery. Just turn it down as possible to conserve energy. That's what "brightness" controls.

Screen Filter, I'm using it right now. Awful developer name though...
I use screenfilter
I've always had to download screen filter
If you're on Android, try this, can be used to dim all bright apps:
Not sure about iOS
With this type of question being asked so often, I'm formulating my own copy-paste response. Here's my rundown:
Location Based Profiles (my favorite use-case of Tasker):
Specific App Profiles:
Misc. & AutoInput Tasks (paired with Nova Gestures/Shortcuts):
Of course these are all over-simplifications of how they actually work. Setting it all up has been no easy task. I've had my fair share of head scratching moments, and battery killing profiles/tasks. It takes time, patience, and the willingness to learn to figure this stuff out and refine it to your liking. Sometimes, you have to weigh whether or not a profile/task is work it, battery-wise. Just take it one profile at a time, you'll learn!

When you need the screen to go darker, use this app: [link] I find the 40%-60% to be the sweet spot and it has no ads.
If there are things that aren't on your phone that are on other Huawei's, this might be worth a shot: [link]
For browsers, I highly recommend Firefox with the uBlock Origin add on: [link]
For ad free YouTube, I recommend YouTube Vanced, I'm not sure if the OG YouTube app has a dark mode yet but this app has had it for a long time now. It also has a lot of little settings that you can't find on the original app: [link]
I'll have time later to find more little things that can help if you want
I have been using Screen Filter since forever and it still works perfectly.

You can turn it down so low to the point that even in a pitch black room, you can hardly see it.
iPhone on newer builds has something like f.lux built in that makes the colors softer --

The app <strong>Screen Filter</strong> should do exactly what you want, and it has Tasker integration as a plugin as well ;)
Here's my rundown:
Tilt the phone a little and put the lowest brightness possible.
This android app might help called "Screen filter".
Search 'screen filter' on the app market. It's what I use all the time.
I've found this works well at night.
I use it for reading on my Nexus 7.
I recommend this one! It's been around for a while and the only one I've used! Never had issues with it
I used to use this one;
Worked for me when I needed it.
Or just make your whole phone dimmer.
Yeah, that's just the brightness slider.
If you want to go darker, I used to use this
Screen Filter lets you choose how dark you want your overlay to be.

PWM flickering on brightness levels less than 100% can be a real annoying on them, but Screen Filter could help.
I use Screen Filter [link] i activate/deactivate with its widget, it remains active unless i deactivate it or reset my phone.
Blackberry Privacy Shade in combination with "Screen filter" form haxor industry.
Waking up without being blinded by the AMOLED.

I just wish i could have it in the toggle menu.
I think the <strong>Screen Filter</strong> app with its built-in Tasker integration will give you a lot of options as well.
Out of the ones I've tried I keep coming back to it. It's super easy on the eyes
I use this app to further dim the screen: [link]
This is not EXACTLY blue light filter, but at least the screen will be dim enough not to blind you
Can't help with TVs, but if you have an Android phone, Screen Filter by Haxor is amazing. I can dim the screen to damn near nothing.
Pretty good and lightweight.
Screen Filter don't lag and no permissions. Try it.
If you're using stuff like this
You can't install apps on android because it can manipulate your whole screen.
I also had a S3 and found this app to be pretty useful when I was in a very dark environment: [link]

Have you looked into Screen Filter? My commute starts around 5:10 am and I love this app.
Screen Filter dimming works with NF
Well then I recommend you to use this:
Android users cam check out screen filter, it lets you add a widget to the home screen to turn it on/off. It easily doubles my battery life.
Just another case that shows how WP is waaaaaay too limited. I once wanted to make this app for WP. Turned out you couldn't run any background apps, so I couldn't make it. It's just one of several apps that can't be ported.
For those of you that want extra battery life I would suggest trying out a screen dimming app such as the I have linked below. I keep auto brightness on and just have the screen dimmed to 50%-75%. When I'm outside I just turn the filter off if it is too dim.
