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
swyped from a galaxy far far away...
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.

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.

So I have an annoyance that I was hoping someone has a fix for. I'm using a wireless charger, Samsung Duo, to charge my phone and S3 at night. When my alarm goes off in the morning and I swipe to shut it off my screen goes to MAXIMUM BRIGHTNESS. This is on the lock screen and it eventually times out. But when I take the phone off the charger, it again goes to MAXIMUM BRIGHTNESS. I'm not kidding when I say it lights up the entire bedroom like a swat helicopter is outside my window with a spotlight! Is this a bug or is there a setting I'm missing?!

Set Auto brightness on a schedule - or - set blue light filter on a schedule - auto does indeed do some unusual stuff.

So it's just the lock screen. As soon as I unlock the phone the screen goes to auto-brightness.
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.
Just got the S21 Ultra (from note 8). Stumbled upon Bixby Routines. It's great.
Always tried using Tasker but never used it much because it wasn't as easy as using Bixby Routines. Tried using similar apps as well but they never seemed to work well.
So far I've got auto-rotate for when I use video watching apps such as YouTube. Power Saving mode while I'm asleep.
Care to share some ideas?
Love Tasker but now giving a chance for Bixby Routines. So far I have set driving profile to start playing YouTube music, set audio to 100%, turn Dolby on, keep phone unlocked. Then Show AOD when charging, auto rotate on when YouTube is launched. Would like them to go crazy like tasker with some Good lock module but doubt it Had few htlm get task so I might go back to Tasker, but imo it should drain more battery compared to Bixby Routines
When i go to work, since i don't touch my phone that often, it auto changes resolution to fullHD, and turns on AOD + turns off bluetooth.
During the night turns on energy saving and airplane mode
Wireless charging between 10p - 7a will NOT fast charge so the charger fans aren't buzzing on my nightstand next to my head.
I hated everything Bixby but I see that I now have to use routines.
Good topic. How to see more useful usages posted.
I use Routines with my Android Car Stereo to Automatically start the Hotspot when it connects to my Cars bluetooth. It also turns up the volume on the phone and reads aloud text messages.
Definitely looking forward to a couple new ideas myself.
AOD & Sync on when charging, off when not charging (apps like whatsapp and outlook have their own sync which isn't affected by this)
Button on my homepage for 5G/4G
Power saving to turn on at 20% (I only turn this on if I plan to go out for the day)
Is there a way to perform an action on switching out of one app to another e.g. To close the app you switch from e.g. Chrome, so that it doesn't chew up battery in the background? Or when closing an app to put it to deep sleep?
I've set it to disable 120 Hz in apps like YouTube and tiktok and games where I wouldn't notice it anyway.
Also set network mode to 3G and disable data when connected to WiFi.

So I think the WiFi one is sort of redundant as your mobile data swtiches off if you're on WiFi with WiFi calling.
The YouTube one is actually a great spot - at low brightness the screen stays in high refresh mode, so forcing it to switch to 60 is useful!
I created a button to force to 2G only in areas where reception is poor and i dont require mobile data (2g gives better reception).
But does anyone know where this button can be used other than as a widget on homescreen?
Set location services on when opening google maps
Play playlist from spotify when bluetooth connect to my car
Put on do not disturb when opening camera application
I love bixby routines, the only thing i keep after debloating a Samsung phone
Anandtech has a write-up on the S21U display. It appears it has the same odd behavior of forcing 120hz full time during low ambient lighting, like the Note 20. The screen therefore consumes more power in dark rooms than in a bright setting. I have an (arguably bad) habit of reading my phone in bed before I fall asleep, and before I get up. So I've set a routine to switch in/out of adaptive mode during my normal bed times, so much of my usage in darkness is in 60hz mode to save battery.

It does this because 60hz changes the tint at low brightness. The oneplus 8pro was bad for this, you could see the display flicker and change tint when the refresh rate changed at low brightness , it was horrible.

I can't comment from personal experience, but from the Anandtech article:
it’s still not exactly clear at to the technical reason why Samsung is employing this limitation in the first place, as I’m not seeing any difference at all in the screen quality when tricking the phone’s ambient brightness sensor and it switching between VRR/LFD on and off.

Regardless, switching to 60hz is a solution if you want to prioritize battery life in those conditions.

Hmmm, I set a routine @ 10PM to switch to 60hz mode, that was supposed to end at 7AM with the actions reversed. It didn't switch to 60hz mode @ 10PM, so I manually switched it, and it didn't revert @ 7AM. I'll try two distinct routines.
EDIT: I set up a distinct routine to set to 60hz AFTER the existing "time period" routine, and the existing time period routine took effect properly this time, so the redundant distinct routine wasn't needed. Don't know why it didn't work the first night.
Brightness turned down and Power Saving mode turned on during my sleeping hours.
I always leave my phone unplugged while sleeping (charge fully before sleep).
I guess if I were to charge while sleeping, I'd plug into a smart plug, then have the plug turn off after the charge reached 100.

Yeah, a couple times my YouTube rotate didn't turn on. But on my wife's note 10 plus, so far has been flawless.
Just bumping this up since Routines is very useful. Been using this since my last phone and it made life a bit easier.
My settings are:
1. IF connected to home wifi, THEN keep phone unlocked.
2. IF charging, THEN sync is on.
3. IF connected to car bluetooth, THEN media volume is set to max and play favorite playlist on spotify.
4. IF time period (12AM-6AM), THEN power saving mode on, DND on, bluetooth off, NFC off.
5. IF camera app opened, THEN DND on.

Oh, gave me a great idea of keeping phone unlocked! thanks. I'll have to set one to keep phone unlocked when hooked up to android auto or the car BT.
I mess with my kids with the Low Battery Announcement (Phone needs charging, Bruh. No Cap). Lol
If it isn't connected to my Home WiFi between the hours of 10PM and 8AM, it alerts me because this typically means that the power has gone out.
