Regardless of what I have the brightness to, it seems display always uses the majority of my battery. For example, I recently flashed G-Lite and fully charged one night, set the display to about 30%, and left my phone idle overnight. In the morning (after about 8 hours) the battery was at 40% and display counted for 60%. The screen was definitely off. I had the phone on the stand next to my bed .
The G2s poor battery life really bugs me, especially after finding out how my GFs iPhone 4 lasts 20+ hours with heavy use.
You mean that the display accounted for 60% of the 60% power lost over night, right?
My opinion? Wipe and reflash if you can. Sounds like a weird random error. Are you running G-Lite 2.0.1, the latest version?

Correct. I am indeed running version 2.0.1.
Setting brightness won't mean much when it comes to battery life because our screens, unlike AMOLEDs drain the same amounts of power regardless of how bright or dark colors are displayed.
I'll have to agree with captainreynolds, try to reflash if you can. If that doesn't work you may have issues with the battery. Battery life is not entirely an issue with the G2, but with android itself, which tends to use more battery when compared to other mobile phone OS's.
Although, I still manage to go through a day with the battery with heavy overclocking (1,6GHz) and above-moderate usage.
Superwiped, reflashed, and still the same problem. Today I had the brightness turned down to probably 10% and after unplugging my phone lasted 5 hours. Display was 64% of the drain (40 mins on).
The g2 can have good battery life, first thing is your battery having these issues no matter what rom? Have you tried flashing a diffrent radio? Does you girlfriends iphone allow her to buy a new battery from ebay for a few bucks and install it herself with out any trouble?

Iphone heavy use for 20+ hours?? With blutooth, wifi, games, txt, videos, web browsing?? Heavy the whole time? I think not. I'm not an android fanboy or anything but that's a lil off.
As far as battery life does it do the same thing on every rom you try no matter what?

This is so annoying. I call Tmobile and they claim 4.5 hours is normal for the G2. On top of that, I can't get a replacement even though I have insurance because it isn't broken, despite the fact that the display is draining an alarming amount of power from two different batteries, regardless of brightness (yes, I have set it to 0% brightness and it only makes a few percent difference on display consumption).
so do you know what radio your on and have you tried changing to a different one?
try typing *#*#4636#*#* into the dialer change settings to gsm only. i know your problem is with display but just curious what affect this has on your battery

Are you running a custom rom? If so you could try flashing back to stock froyo then see how your battery life pans out, or u could unroot then root again.
If worse comes to worst I can recommend an extended battery for better battery life.
Could re-rooting fix it? I've been rooted since I got the phone in Dec '10

You are confusing the brightness (%) with what colors are displayed. The brightness absolutely affects battery life, as I can get up to 30% more time between charges by going from "Auto" to 35 or 40%.
What you are thinking about is the actual colors displayed, such as black versus white. On an AMOLED screen, displaying lighter colors consumes more power than than darker ones. So having dark wallpapers and interface screens can actually help with battery life. Maybe one of the reasons that the AOSP Android theming uses so much black?
With LCD type screens, the color makes no difference. The same amount of backlighting is being used regardless of whether the screen color is black or white. This is completely independent of the brightness %. So you can be displaying black, and still have the brightness at 100%.

Rooting is just giving SU permissions. Just giving yourself SU permissions again shouldn't change anything.
i too have this problem. i have read somewhere, a topic on xda, saying that its the connectors and flex cables in the phone. something about wear spots on the flex cable makes the plastic rub off and you end up seeing bare metal on the cables.
try sliding out your keyboard half way, and look at the flex cable. do you see any of the metal hanging out?
HI all,
Here's the deal.....coming from a Sony Xperia S after 3 years loved that phone ....i bought the P8000, i know a good bit about android and I'm very happy with the phone so far,,,,just have it two days rooted and custom Rom already...
One thing so far that annoys me is the notification light staying on (breathing) until the notification is looked at...when your spending half hour chatting the ladies its annoying......now the xperia s the notification light would turn off as soon as screen comes on ...makes sense because the notifications are on the bar anyway...
Is there any solution to this? App..software or execute script at boot?
If there is a solution i will write something to make the light breath brighter!
TIP:
The phone will charge at its fastest rate when totally left alone, because of heat generation from charging..... and if the phone being used at the same time, the charge current mA will drop in ratio to battery temperature rise, it is regulated to protect the battery from over heating and possible explode!
Change your cpu governor to on demand from interactive saves a bit more battery.
Anyone else think the brightness is not very bright? I have turned auto brightness of but slider is on around 75 to 80% in normal conditions?
Seems fine to me. Depends entirely on what you are comparing it to, though.
With the brightness dialed all the way up, it looks either brighter or dimmer than my P2XL depending on the angle, so...
I have come from iphone x and (work phone) huawei p20 pro.
Right way up or 80% is fine but say half way 50% is loads lower than most other phones

The display could be brighter, I feel 100% should have been what 90% would be. 50 and below is too dark to be used at all imo.
If it just flat doesn't get bright enough for you you're kinda screwed. If you're wondering about auto brightness you gotta keep on cranking it up for a week or so before it starts giving in and giving you what you asked for; at least this was the case with my 3 XL. Seems to be the case here, mine is still slowly but surely getting brighter as I keep on dutifully upping it to the desired setting in various conditions. It worked very well before, the best I've used so far and I'm hoping the same will go on here.
The auto-brightness is supposed to be fairly intelligent BTW: As an example it's supposed to recognize the middle of the night and that your sleeping and turn the brightness down more with the same brightness information available than it would in the early evening when it knows you're awake. As an FYI the adaptive battery feature also seemed to need some time to figure out what it wanted to do. I had my 3XL for about a week last fall and the battery situation was slowly but surely getting better every day just like the auto brightness. No idea if either would have continued to improve after I sent that one back but they both needed time, that was for sure.
I've configured my screen brightness to maximum and disabled "Adaptive Brightness" and "Comfort Tone".. Despite this, the device "decides" from time to time to reduce brightness.. How can I resolve this? I want brightness to be on maximum all the time no matter what..
I'm guessing that is does this because it's bad for the device to have full brightness on all the time.
First of all, why would you want to be on max brightness ? It will hurt your eyes in the dark, drain your battery and it may cause burn-in in long term.
Anyway, to answer your question, it reduces its brightness probably because of heating. An higher brightness means a higher temperature. To solve that, it may be possible to do that via magisk but i've never heard of something like this. Or you could try some custom roms that don't include that type of software cooling system.

Thanks! When the brightness gets low it hurts my eyes.. On my smasung galaxy s21 ultra, it never reduces brightness.. Why? simply because that's what I choose. It seems that oneplus would not let me choose to work with high brightness all the time.

Oh i see. Isn't this related to DC dimming ? If so some custom roms may support that.

Low brightness doesn't harm your eyes. It may cause muscle strain because you can't focus properly; harmless.
Full brightness can demage your retina over time especially viewing it in a dark environment.
Full brightness will greatly decrease the display lifespan of a AMOLED.
The blue pixels die first.
Use manual brightness control and try to limit it to no more than needed, 50% or less is best.
Do not use in direct sunlight for more then a few seconds.

Except it's not a bug. It's a feature. More likely multiple features designed to improve the health and longevity of the device. That said, I'm all for individual choice. If a user really wants to risk damage to their device as well as their own vision, they should be free to do so. It does make sense, however, that such an option wouldn't be in plain sight in the Settings app.
Have you tried any 3rd party apps that support High Brightness Mode/HBM? Most will probably require root since HBM is a hardware-level setting (brighter than just moving the slider to max). I don't know if there's a way to do it more permanently with adb or not.

Custom roms are always dimmer than OxygenOS, have you never noticed this?
On OxygenOS I can have my brightness at 50% and see the phone fine, on custom roms I need to have it around 75-80% to get the same brightness

Don't know, I haven't tried custom roms yet on my 9 Pro. But I remember it was like you said on my 5T.
I've got myself a new P6P and basically since day one, every night or every other night it would lose something like 15 to 25%. This is over roughly an 8hours sleep.
Device is connected to WiFi and always on display is disabled.
Gram battery graphs look scary, like Oreo times scary.
Is anyone else experiencing anything similar, or is it just me?
Hibernation while screen off seems totally off at 27% of the time (should usually sit around 90% unless for example streaming or downloading stuff with screen off).
My previous P5 would do considerably better, with an almost flat graph in the same test conditions.
Thanks!
And the most frustrating about all this, is that in 2021 Google still can't provide us an easy way to figure out what's wrong.
Over several iterations they've promised we wouldn't have to deal with crap like this ever again (Doze, Doze on the go), but ultimately when it happens, users have no clue.
I'll have to install battery historian once more. I thought I was done with this crap.
P.s. I'm of course very interested to know what YOUR numbers look like in similar conditions. Thanks!
Hey,
I was having a similar issue on my P6Pro with high idle drain (about 1.8% to 2% per hour) using AccuBattery Pro to measure over the last week (got my device last Tuesday).
I just rooted last night so effectively did a fresh install on the November firmware. I turned off AOD, Digital Wellbeing and Lift to Wake as part of this.
I haven't really used root to prohibit anything I couldn't have done without root (yet) and last night used EXKM to track stats.
Over 7 hours I only lost 2% battery and had idle drain of 0.28% per hour which is much much better.
You've already said AOD is off but not sure about Digital Wellbeing. I'm not sure if the factory reset and setting up straight on November firmware helped the situation but might be worth a go?
I quite agree. Everytime I get a new device (have usually been from Google), I have to start off troubleshooting battery drain and installing other apps to do it.
Android 12 has light doze now, so after just a few minutes it will stop apps accessing the network, and force apps that need to get some data every few minutes or so, to all queue their requests for the next maintenance window, so this should very quickly after the screen is off, allow the phone CPU to enter deep sleep for most of the time, i.e. nothing is running in Android until the next maintanence slot.
What is likely happening is there is a wakelock stopping the deep sleep from happening, and Andriod remains running doing very little, keeping the CPU awake ticking over at 300MHz.
To test this theory install CPU Spy https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy&hl=en_GB&gl=US Have a look at the stats, has the phone entered deepsleep and what is the percentage of deep sleep? Overnight the phone really should be able to get at least 80% deep sleep as no one is using it (I've seen 95% on tablets and my Pixel 2 XL overnight).
To run a quick test, reset the stats, and let the phone sit for 30 minutes or so without being used, then go back to app (will need to use Refresh to get the latest totals) and see what percentage you get of deep sleep.
If you find the phone is going into deep sleep okay and overnight is 80% or more of deep sleep, then that isn't the cause of your battery drain, and it is likely caused by either the modem flapping or constantly trying to register with a cell tower, or perhaps Wi-Fi. So your next test is airplane mode overnight.
My overnight losses are around 5% at the moment, I'm only on Wi-Fi overnight, the mobile network is off as I get next to no signal.
Mine dropped 20% in 8hrs over night, seems a bit excessive.

I'm super paranoid about this stuff, and so since I knew that an OTA was in the pipe when I received it, I just skipped the first time setup to go straight to System Update and install the OTA
Then I factory reset, and only THEN I set it up properly with my Google account etc.
So I guess this answers your question
Digital Wellbeing is on for me tho (lift to wake is also off, as it tap to wake - although there's the bug, I think, which would still enable the screen in B/W mode when phone is lifted).
2% in 7 hours is awesome, that's what I'm aiming for, but I'm really not willing to root
I guess I will re-factory reset and maybe installing apps in batches, instead of all in one go...
EDIT: just re-read your post and you said you haven't made any of the root-enabled modifications yet, so even more call me amazed. I guess I'll also try disabling Wellbeing at this point...

It is, especially if you consider that it's 1000mAh.
A Pixel 2 XL dropping by, say, 10% (which is still much higher than what I used to get), means a consumption of 352mAh.
In terms of efficiency, a crappy P2XL performace is still thrice as efficient as what we're seeing here on the P6Pro (and ideally tech should move forward and become MORE, not less, efficient...)

Yeah,
In terms of root, I hadn't done anything with root until this morning really so there shouldn't be anything affecting my idle drain figures that you wouldn't be able to do without root.
Otherwise, try turning off all digital wellbeing features (bedtime mode, timers and focus mode) and remove permissions to digital wellbeing and then clear data. Try that for a few days and see how that has an impact.
I've noticed the same issues, I would normally have my phone switch off over and and switch on but this doesn't seem to have that option

Quite agree with you there, my Pixel 2 XL often goes 5 or 6 days without needing to be charged, although to be fair I'm working from home and it gets little use during those days and only on Wi-Fi for most of it. so not typical usage. I don't think the Pixel 6 Pro will go as long, in theory with exactly the same usage it should go for longer as larger battery and newer chips sipping less power, certainly when doing little in standby.
Too early to tell if the Pixel 6 Pro can better 5 or 6 days as I've been playing with it a lot more, but in theory it should without question, so something is seriously wrong it it can't.
As for the Pixel 2 XL, I dip into it now and again, and the one thing I'm missing on the Android 12 is not getting true black, why have they made black dark grey on all the setting pages etc? Why reduce contrast? I'd love to be in those design meetings just to see what rubbish they come up with to justify some of these changes.

IIRC full black will cause smearing while scrolling. And the display of the P2XL was, let's say it, crap.
The Pixel 2 XL display looks absolutely fine to me, and I have never seen any smearing when scrolling. When we had LCD everyone was raving about OLED having true blacks, and everyone wanting a dark mode, now in many places in the UI it looks worse then most LCD panels for contrast. So its now fashionable to have artificially lowered contrast.

Android 12 has tweaked dark mode again in its second developer preview to make it even lighter than the previous release.

Google, give us the option to change it back, it is suppose to be Material You so we can go back to customising again (like we once had), but it seems the only options now are washed out pastels.

Go to settings, Digital Wellbeing and turn off all the options if you turned any of them on. Go to Settings, Apps and then find digital wellbeing and remove all permissions, then within that section also wipe data for Digital Wellbeing. That pretty much resets it back to stock. Without root, you can't freeze the app or remove it but this should be good enough.

Mine lost about 7% overnight last night. I've read on this forum that they aren't sleeping well. With two adb commands I installed Nap Time by Francisco Franco and it seem to be going into a deep sleep when not being used now.

I've got NapTime as well. The trouble is light and deep doze is just the Android OS restricting what apps do and forcing them into maintenance schedules so things are done in batches. So its an app thing rather than a low level forcing of the phones CPU to sleep, so even in light or deep doze it doesn't guarantee that Android has been halted and the CPU is in sleep, that is another thing step. It should make Android more likely to suspend and the CPU to go to sleep if Apps aren't allowed to chatter over the network, but deep doze doesn't guarantee the phone has gone into standby.
Other things can prevent the device from truly suspending and putting the CPU into sleep mode, so other things may be happening, it might not be an app issue.
To check how long the CPU is in deep sleep (essentially the phone is off and Android is suspended and is what we need to see so top battery drain overnight) CPU Spy can show you that, currently mine is showing 82% deep sleep overall. When you see a low percentage of deep sleep and high percentage at 300Mhz, then something is stopping the phone for sleeping, so it is kept awake doing little so idles constantly at the lowest CPU clock speed, but this still uses quite a bit of power compared to deep sleep.
The age old question for those of you having battery drains, Did you turn off wifi scanning?
