When the battery gets low (not sure what percentage), the screen dims and there is no option to turn up the brightness. Is there a way to change this on a rooted Tab? Is it possible through the development API to adjust this, so that it can be implemented in an app?
Charge your battery. It comes on when like 5% remains anyway.

It comes on when there's 15%, as I got two more low-battery notifications after that. The problem is the tab is almost unusable at that brightness (especially outdoors or in a car during the day) and since I ran it for two more hours with Angry Birds and YouTube, I've lost two hours of battery life period. If it let me adjust brightness, I could at least use it until it depleted.
There has to be some way to change this, even if I have to root it, change a config file, or write an app to let me change it. Does anyone know how to modify this setting?
Genuine question only because it wasn't mentioned. Auto brightness isn't checked right?

Brightness was checked the first time, the second time it was unchecked and all the way up.
Did you notice, the backlight for the four haptics buttons at the bottom will also turn off at this point, which makes them impossible to see when it's dark.
You need check then uncheck auto, you be able to change the brightness

I'm having the same issue. I have a battery issue where my tab displays 1% when I have 20% or more remaining. Was wondering if you found a fix to this.

I just bought a new Captivate (first android device) which I upgrade to from a Nokia E63. I've been playing around adjusting settings etc. and I noticed that my battery is more than 20% drained already! Is there something wrong with my model? If not, what can I do to save my battery for when I really need it?
If all you're doing is playing with it yes its gonna go down. Also depends on what programs is any you have running in the back ground. Furthermore if your wifi Bluetooth and GPS are all on there's another drainer. Last make sure you have the latest update. Usually the out of the box captivates don't have the 2.2 so use the kies program that's on the disk that came with it.

If the battery is new its going to drain quickly at the beginning, after a couple of recharges its going to get better. Other than that i would set the display brightness to auto and i'd download green power free from the market to toggle wifi/data and have it turn on for 1 minute every 15 minutes to save the battery.
i never understand why people complain about battery life cause i can go more than a day without charging, but here are some tricks. turn off wifi, and blue tooth. also under volt your cpu to save more power. also get a dark background because amold screens use no power when displaying black.
It is all in the way You use it.When you are surfing the net and just all around using the crap out of the phone battery life will be horrible. once the new smartphone phase wears out that battery life will come back up. On moderate use I get a day or better. on heavy use I get 4 to 7 hours maybe.

Big difference regarding the display technology between the two phones. It's the price you pay for the AMOLED.
Don't use auto brightness and keep the setting to its lowest if at all possible. An app called Screen Filter is helpful during night time reading.
Just make sure you let your battery drain until your phone shuts off and give it a full charge. You should be good from there.
Battery Dr is a good apparently. Just fyi

I use two batteries a day due to my long train-commutes to and from work. That means I will go past the 15% and often 5% low battery warning prompts. The prompts very often come up when the Note is in my pocket or the screen is otherwise not on. Turning on the screen twice to warn of a low battery is kinda like sounding foghorn each time silent mode is activated. Sort of undoes itself. So I'm out for a solution. Any suggestions? Thanks guys.
I am with you. I hate that warning. I have three batteries myself (including the stock one)
Sent from my GT-N7000 using xda premium
There's got to be some root app that let's you change up the percentage when the warnings occur. Can't you do that on CM9?
Hi,
My Screen Dims on low battery, even when Power saver is turned off. This behaviour shows since update to 4.1.
The integrated Power Saver is set to :
Turn Power saver on : at 50% battery level
Brightness : 50% Brigtness
Powersaver : OFF
But still when 5% Battery is reached, the screen goes totally dark.
So dark I cannot read it most of the time. I have to use my hand to cover for shadow, set the brightness up, and then I can use my phone again. This makes toe phone unusable when battery is low.
I hate this behaviour and would like to disable this.
How do I disable it ?
As mentioned, this was not the case with Android 4.0.3 (stock, rooted), it happens since I updated to 4.1.2 (stock, rooted)
The intuitive place to look ws the power saver, but those settings seem not to change anything.
I have searched the net and these forums, but could not find a place where to correct this settings.
I would like the screen to remain it's last setting, not dim at all.
Please help.
You didn't set the brightness to auto, did you? Because this is maybe the cause of dimming. I'm not sure but that's my first thought.

Nope, tried both, auto and non-auto, in both cases when the 5% battery warning comes, screen is set to lowest possible level automatically, even in bright sunlight outside. In winter maybe, but in summer it suxx. Some automatic adjustment according to ambient light -might- be ok, but I would prefer that the backlight level is not changed at all.
Are you on stock? Or any custom rom?
I think you can maybe change this setting in build.prop or smth similar,
but I'm not that good when it comes to this.
Sent from my LG-P880
As I said in the first post, I use stock rom.
I have now looked through build.prop file. There is a " #Backlight " section, in there is some " ro.lge.lcd_default_brightness=146 " entry. I will change it and see what happens when I hit 5% battery. But since there is no other setting (like when battery below 5%) this does not look very promising..
Does your P880 show the same behaviour ?
It actually did the same when I was on stock (now I'm on WerewolfJB) but it didn't bother me back then (almost never got my phone below 5% battery.
And because I'm not on stock I can not look for the right line in build.prop or other system config files.

So there is no "OFF" in the powersaver, it defaults to some weird settings when switched "OFF" ?
I will try that too.

^works!
but for me after i lock the screen and un-lock im back at screen min, i had to re-open rootdim each time and set it. even the "lock" feature doesnt seem to overthrow the system 5% batt life force dim. annoying but at least rootdim works, even if i do have to open it each time
disable low battery dim

thanks the root dim it does work, you have no idea how long i search for this.Funny thing i came across this root app like 5 or 6 times and didn't think it would work cause i have lux dim the other root app and that one does bring the display back to 100 percent bright who would thought that the fix was this simple and yes like you say every time you lock the device it brings you back to dim mode but if you open the app and bring the slider all the way up it stays like that at 100 brightness, done that on my rooted galaxy s4 from cricket it works yey.

There is one now
Auto brightness is a battery killer for me. I usually have it 20% all the time. Seems to be the sweet spot for me. Great battery life.
I don't use autobrightness. It wastes power constantly polling for lux values. I just use "display brightness" to put an invisible slider up the right side of my screen.

I just leave Lux on Auto Brightness and Dynamically, and let it do its thing. I don't mess with the levels or anything. It's far superior to the stock auto brightness right away
I use stock auto brightness :/, anyone use full brightness?

Auto brightness on N5 is buggy
I had a N4 for a year and auto brightness worked fine but on my N5 I find that auto brightness bounces the brightness around frequently and seemingly for no reason. It surely must be a software bug?
Using stock AutoBrightness and get 4hrs SOT with 2-3hrs voice calls so that's good enough for me. My Nexus 5 last longer than my Nexus 4 for sure with the same checking/usage during the work week, I can go 1 day 16hrs with this before it's fully dead.
Right now i'm 22hrs 23min 56s on battery and have 31% remaining. Being today is weekend I have 2hrs 15mins 12s screen time but 3hrs, 41min 18s voice calls. Obviously bunch of SMS and Hangouts today as well.
Use lux auto brightness... Its bettr than the stock one...and doesnt battery too if the settings are proper!!
Dont frget to press the THANK button!!!
I keep switching from and to auto brightness because I don't want to flash a modded kernel to avoid losing official updates, but I really hope Google will fix it soon
Luckily there's an app called Profile Scheduler which I set to automatically lower brightness when I'm home (connected to WiFi or recharging) and at night
I don't use auto unless I'm out in the sun...
After using Flux on my desktop and laptop, I have grown accustom to the features the night mode brings and needed to bring it to the mobile phone as well. Using lux as my auto brightness go-to app and has served me well with it's profile editor and being able to go (negative) in brightness which helps my battery life.
Nexus 5 4.4.2
I simple automate my brightness to change by time of day. Using 30% during the day, 20% at night and 5% before bed as set in Llama.
The times will need to be adjusted as the daylight hours change.
So far so good
Its so much better than my Hercules was
Nope, I never use auto brightness. Just crank it down to the minimum while I'm inside, use screen filter in a dark room, and crank it up until I am satisfied with the visibility when I'm outside. (Depends on how sunny it is out.) I've always liked changing it myself because I don't find myself changing areas of lighting all that very much. When I'm inside, I'll probably be inside for awhile. When I'm outside, I'll probably be outside for awhile, and so forth.
I tried out auto brightness again and it would seem 4.4.2 has tweaked it for the better. Its actually useable now for me and gets the brightness even lower then I had it indoors. Not sure how much battery the sensor uses but having lower brightness all together might make up for it.

I'm actually using it stock, it's quite good really
never used autobrightness..usually i keep phone's brightness set about at 20%..i see autobrightness consumes a lot of battery

The sensor itself uses negligible power and makes no difference to battery life.
I've tweaked the framework-res.apk file to use more brightness steps and to be dimmer in darker conditions. Saves installing an app when the phone has it built in. If anyone is interested I can post it, needs flashing with TWRP or other recovery.

How do you control screen brightness on your Pixel 4 / 4 XL?
To help battery life, I have read that Ambient display or Adaptive Brightness and that EQ thing too, can be a bit of a battery drainer, and it's best to just set your brightness yourself. But there's no easy quick way to do that it seems? Other than going into Settings - Display, and sliding the bar up or down to get the specific % you want.
Is there an app, or what are you guys doing?

I'm a full manual kinda dude. Inside, i'll set it at 50, then up to 90 or so when I go outside. If it's really bright, then i'll hit my HBM widget :good:
I run it with adaptive brightness on and ambient EQ on. Time saved on micro managing something like brightness is worth a little battery life. I calibrate my adaptive brightness to 0% in pitch dark and don't touch it anymore.

Auto!
I used to use manual for my OnePlus 7 Pro because that thing was horrible with setting brightness for me. It would always get too dim. This Pixel, however, has solid auto brightness and doesn't drastically increase or decrease.
Battery life part isn't an issue for me since I don't really notice a huge drain with it on + I'm almost always around a charger anyway.
For those that aren't aware the auto-brightness on these phones takes quite some time to fully adjust to your preferences. You need to keep fiddling it every time you're not satisfied and it will remember the setting you made, make note of ambient light, time of day, etc. and adjust accordingly until it has you pegged. This takes days, a week, more or less. Dutifully counsel it as to correct brightness and you may just find it works very well and can be left alone once you've got it in line. Think of it as a stubborn dog that must corrected until trained.

Not for me. I literally just put it to 0% in pitch black and, for me, it's adjustments to all other ambient lights is perfectly fine for me. But you are correct that it can take some time but I say within a week and not multiple weeks.
Sent from my Pixel 4 XL using Tapatalk
I didn't say multiple weeks, I meant the time can be days or up to a week more or less, sorry if I didn't phrase that well. Mine was about a week as was the previous pixels before it. Anecdotally it seems it takes longer if you prefer your phone brighter in general but that's just based on my reading different observations people have had of it. Your own tend to fit that mold, you clearly prefer it dim(mer) simply because the phone really likes to keep it down in the stock model so if you were good to go with just one adjustment you lean that way.
