[Q] 4.4.2 Battery Life issues - less than 25% total life compared to previous version

Hello, new to the forums here. I recently updated to 4.4.2 on my LG Optimus G Pro and I went from having a battery that lasted all day, sometimes two days to my phone being dead by the time I get home from work for the day ever since the update.
Two days ago I had 1hr18min of screen time within a 6 hours off the charger and the phone was at 15% battery life left. Today, I had 13 minutes of on screen time and at the end of my 6 hour shift my phone was at 40% and dead a few hours after I got home. I have GPS, bluetooth, NFS all disabled and my brightness set to 30%.
Any help would be greatly appreciated, I'm thinking of doing a factory reset and just not updating to the new version of android when it prompts.
Thanks

Get betterbatterystats and see if you phone deep sleeps. If not then check what the wakelocks are in partial wakelocks. If it's a kernel problem maybe you need to flash a different kernel.

i am running stock phone. it is not rooted or anything

Same exact battery drain problem. Im on stock e980 rom (rooted) with no custom kernel.
Gsam battery monitor app is showing the kernel as keeping my phone wake for the entire time my phone has been unplugged.
The problem seems to come and go though. One day itll be fine, but another day the battery will be sucked dry fast.

I'm running stock rooted for e980 and have pretty good battery life .... Try clearing Google play services data and rebooting ... Check and see what's draining your battery mol its pretty easy

I'm also running stock kernel, and have great battery life on kitkat. Just reset your phone to factory defaults

I've done this twice in the past 3 days....
I'm sick of having to set up my phone over and over again. And this is a new phone too. I just got it Monday under warranty because my old phone broke.
It's getting annoying. I used to get 14-17hrs+ of battery life (casual use, usually ending the day at 30-50% too, so I never even reached 0%) with my old phone on Jelly Bean. Now with Kitkat, I get around 6 hours if I'm lucky! According to Wakelock detector, my phone is awake 85%+ of the day! All it points to is Kernel (Android OS). I see lots of Wlan_wake triggers too, so I suspect wifi, but even with wifi off, the drainage still occurs. And I only have a 2GB data plan shared between 3 people, so it's not like I can just use data all the time either. I actually NEED wifi.

do you have an SD card installed? Maybe you can try to remove that and get rid of all other media from your phone storage. Might be a media scanner problem? Or maybe you can try to disable auto sync, and check if Google play services is the culprit.

The media scanner usually shows up in the battery stats window though, and it isn't. I've had a corrupted SD card on my tablet once before and it caused media scanner to go berserk, but the Mediascanner entry appeared under Settings>Battery as the highest battery consumer.
In this case of my phone right now, it is Android OS in Settings>Battery. According to Wakelock detector, GSam, and BetterBatteryStats, it's more specifically Kernel.

Have you tried reflashing your firmware, instead of just doing a factory reset?
I assume you are rooted since you are using BBS and wake lock detector on KK. Why not flash a custom rom?

Hi i had the same problem as you but i started digging inside the system of the phone i found the problem but you will require root access. If you have root you have to delet a lib file tand it carrier iq wich run in background and drains your battery the file to delete is libiq_client.so do that and you will see an increase in battery life

I did this on Tuesday or Wednesday.
... I messed something up on my phone while trying to install a custom recovery, so I was basically forced to reinstall everything. I'm on stock ATT e980 ROM (on an E980) + root. I reflashed the Jelly Bean tot file and then did the OTA update with no apps installed.
On the phone that got warrantied, I had flashed the E980 kitkat backup (now has a flashable version too), and the battery life seemed to be much better on it for about a week, and then the issues started there too.
I just rebooted the phone into recovery and wiped cache and Dalvik cache. Many people on Kitkat are reporting that this helps, but only for about 2 days then the issue returns. Obviously, I want a permanent solution.

I didn't see this part of your message, but I just had to respond lol
Yes, I'm rooted and I absolutely hate custom roms. They take out all the features of the phone that I originally bought the phone for, like Smart Screen, the IR remote (yes, I know it can be ported), and the quick memo button. Plus I used custom ROMs on my old SGS2 and they always caused me tons of problems. Crashes, overheating, random reboots, random SODs, etc etc etc. Plus I hate the AOSP feel. I know it's true Android, but I just don;t like it.

I'm still getting more than usual battery drain, but it is better now.
I just got a replacement OEM LG battery, so I will try that to see if maybe the battery is defective. When I got my phone replaced under warranty, they didn't have batteries in stock, so they just gave me back my old one and ordered me a knew one. The old phone was overheating a lot too, so maybe the battery is bad.
UPDATE: OK, MUUUUUUUUUCH better battery now!
I put in that new battery and "recalibrated" it by draining it to 0% and charging with the power off. Once it reached 100%, I let it charge an extra hour, unplugged, and started up the phone.
I also installed Qualcomm Snapdragon's Battery Guru. I set it up so that it's mostly managing app syncing, but I also set it up so that it will not rely on location services to turn on/off my wifi. I don't want to leave my location services on all the time. I don't know how it is on Kitkat, but on older Android versions (ICS and GB), leaving GPS on was a huge battery drainer! I still treat location like it was back then.
Anyways, it will take a few days for the app to learn my usage patterns, but it's already helping by making certain apps only sync when I open them, etc. I suspect that all the wlan_wake wakelocks are being caused by auto-sync but I'm reluctant to turn it completely off since i rely on it to sync my work schedule, calendar, etc between my phone and tablet. I just wish there was a system setting to allow auto-sync to run every X hours or something. I really only need the sync to run every 6 hours or so.
It's been about 35mins now with 6mins of screen time and the phone is still at 100%. A few text messages and the installation of Battery Guru too. This is normal and how things used to be. After a while, the phone will most likely go to 99% and then have faster drain, but it shouldn't be so rapid like before. Earlier today, after 30mins, the battery would be at at least 95% or lower by now! After a full day, the battery usage graph would should a 45 degree angle too! It used to be an almost level, very gradual angle instead.
I should also mention that for a while, I was using a Zero Lemon slim battery (3150mAh). I bought it because of all the hype Zero Lemon was getting here on XDA, but I really regret it now. I used it for 2 weeks (1 week on my broken phone and 1 week on my replacement) and the drain wasn't consistent, even after several calibration attempts. It lasted me all day though, but I'd be stuck at maybe 3% for like an hour, then while in deep sleep, the battery would "magically charge" to 6%.
After I swapped back to the OEM battery, I don't think I recalibrated, so I wonder if my phone thought I was still using the Zero Lemon.
I'm planning to return the Zero Lemon.
UPDATE2: It's been a couple hours now and the Android OS is starting to retreat from the #1 slot in the battery consumption list!
Screen is #1 now and Android OS went from 65% usage to 14%! :good: :good:
UPDATE3: :crying: OK, it's broken again. I didn't do anything to the phone, but when the phone hit 50%, I left it alone for 2 hours and the battery drained 30% while it was supposed to be sleeping. Android OS is back up to 80% usage!
Wifi on, Location off, Bluetooth off, auto-sync on. I'm trying auto-sync off today to see if there's any dramatic improvement.
UPDATE4: I might be on to something now. I noticed 2 things: 1st, when the screen is off and the phone is SUPPOSED to be in deep sleep, the back of the phone stays warm to the touch. It wasn't hot, but it was warm enough to be noticeable. 2nd, I had System Tuner installed yesterday but uninstalled it this morning. Despite uninstalling and rebooting, the phone was still draining battery fast (I still lost 25% in 2 hours today!). I noticed that System Tuner had added a script to System/etc/init.d, so I deleted that and rebooted. Now the phone seems to be sleeping (says so in BetterBatteryStats and WakeLockDetector), and the back of the phone is COLD to the touch when doing so. I took a shower today (I take fairly long showers too LOL), and then checked my email, and the battery life didn't decrease at all during that time while it was asleep.
Obviously, I need to test this throughout the day now, but this is definite progress, if not the solution.
Also, on my warrantied phone, when I had the Zero Lemon battery inserted, battery drain was high (battery's fault), so I installed System Tuner then too, trying to tweak the phone. After switching back to the stock battery, the drain remained, but most likely due to System Tuner's script.
Then when I got my replacement phone, I ALSO installed System Tuner and of course, I got battery drain issues! I factory reset, but did not install System Tuner, but the problem still remained. However, it probably remained because the reset doesn't remove system files, so this script was still in the init.d folder.
FINAL: I ended up flashing the stock ROM again (I used Eazy Kat 1.0 this time). My phone began bugging out on me. Random crashes here and there, mobile data randomly disappearing (no LTE/4G/3G at all), and worst of all, people were having difficulty hearing me during calls. Reflashing seems to have worked perfectly this time. *knock on wood*
FYI: The last flashes I did, I used .tot files to flash back to stock Jelly Bean and then updated to Kitkat via OTA.

I stumbled across this post and tried that fix. I'll check back in later to see what it does.

High held awake time and battery drain

So my battery on my phone seems to suck... I just made a full wipe clean install of ICE Rom 3.5.0 with cleanslate kernel, balanced pnp profile v. 22, magisk root and got a whooping battery loss of around 30 percent overnight!
I was using stock before and had around 20 battery loss overnight, which sucks and is the reason i wanted to try a custom rom.
My phone is already 4 months old and I did a battery diagnosis, which ended with 94 percent (which is good right?).
Can anyone please help me?
I don't have Facebook or Facebook messenger installed, turned of WiFi and Bluetooth Scan and Location Services.
And I'm using Greenify, although I didn't greenify any apps yet

What email app are you using? How have you got it synced? See how many times it wakes your device using Gsam or some similar app. This was my battery drainer (I use Bluemail). Anyway, check that out first.
20% battery loss overnight is horrible. Something is not set up correctly or is misbehaving.
Reboot your device and let it set for 2 minutes. Now go to System/Settings/Developer options and select Running Services. Everything look OK there?
I cant see your screenshot.

Yes, I lost the same amount although I had the phone in flight AND extreme energy saver mode...

I'm facing the same problem after i updated my Firmware to 2.28.617.6. My Battery Usage show 45% of ANDROID OS an 39% of ANDROID SYSTEM, I'm already tried Viper 4.1, 4.3, 4.5, 5, 5.1, all with the same problem.
I updated firmware using RUU.exe, and i already updated firmware again to 2.41.401.3 with RUU again. Same problem
I realized the problem is not with rom, all of then, stock or custom, show the same situation. Its a firmware problem with Nougat
My phone is a Unlocked version, with S-ON
Any help?

I would perform a full wipe (+data!). Reinstall your Rom freshly, and the problem should be gone.

I'm already did that, all ROM's installs i did with a clean install.
With no one third app installed, the problem persists
i'm already tested turn of wifi, bluetooth, location, put phone on save battery mode, restart all permissions
Nothing helped
The main question is thats something who did not let phone enter in deep sleep

Yeah I've got the same problem with Android OS and Android System (the wakelocks are HVDCPD_WL and NETLINK) keeping the phone awake and preventing deep sleep almost 100% of the time, which is absolutely killing my battery life.
Frustratingly, the problem is not solved with a full wipe + reflash of any ROM. I originally had the problem sometime after the stock 7.0 OTA upgrade, at which point I unlocked the boot loader, flashed Maximus HD, then the problem went away for about a month until just returning a couple days ago. I've tried flashing the latest Maximus HD, Viper, but nothing is fixing it so far.
I bet it's some kind of hardware issue. I'm almost at the point of giving up and getting a OnePlus 3.

Just sharing my experience: I tried every Sense-based ROM I could find, problem of phone not going to sleep persisted. Even tried RUU to latest 2.41.617.3, which of course wipes absolutely everything - same problem, phone not going to sleep. As last ditch attempt, flashed the LineageOS Jan 28th nightly, and the problem is gone. Phone sleeping properly and battery life is back to normal. Not sure if coincidence or what... Going to stay on Lineage for a while as it works pretty well, but will go back and try Sense again in a couple weeks maybe.

This issue started to affect my phone while still on Marshmallow, around 3 weeks ago. It felt like it started after updating an app. This is what prompted me to update to Nougat. However, the issue persisted, even with full wipes, and even with LineageOS installed.
Moving from stock ROM to LineageOS has reduced battery drain from 10% per hour, to 5%.
Airplane mode and battery saver mode makes no difference to the drain. Neither does any WiFi and GPS setting changes - I have already read about a few possible "causes".
Perhaps the only option is S-OFF and re-flash all partitions of the phone?

Running a RUU would be your best option. This will wipe the phone and restore the stock ROM (system, firmware, etc).
Have you looked at wakelocks or app usage to see if there is any unusually high usages? I had a problem with my 10 awhile back that ended up being a particular version of Google Play Services. Usually these issues can be traced to a particular app or setting, it's just a matter of knowing what to look for.

Ohio wake_lock and no deep sleep. Same issue after reflash ruu, lineage, viper... on all roms same issue and no deep sleep. I think it's hardware issue. I try to flash elementalx kernel and it fixed problem for a day, one day only. Worst phone ever for me.

How do you make a battery diagnosis?

Hi, since about a month I've been having the same issue, the kernel HVDCPD_WL and NETLINK wakelocks are keeping the CPU in use and consuming the battery charge at a rate of about 10%/hour. Has anybody got any new info on this? I read of someone that claims of having fixed it by cleaning the usb-c port, but in my case it doesn't seem to make any difference.

Nougat battery drain

Okay so, I flashed the latest Resurrection Remix yesterday, great performance ; however, there's a weird battery drain occurring to me. I've already tried multiple guides using greenify, amplify, etc but none really worked. I was using Viperrom 5.10 and wanted to revert back to complete stock after noticing random restarts and this battery drain. I installed stock through twrp with the backup I had before flashing and rooting then installed the stock recovery but still there was a battery drain. I flashed Leedroid, PureFusion 7.1.2 and still same problem. I think this is caused by something in Nougat since all the ROMs I flashed were nougat and showed the same issue. Now, I've seen many people experience the same problem but no one found a proper solution. Any insight as to whatever causes this battery drain would be appreciated. I'm not a heavy user at all; I don't have any games and all my apps are basically just social media like Telegram, Whatsapp, Youtube, Instagram and get barely 2.5hrs of SoT. Something to note too, my phone reports illogical battery percentages and sometimes shuts down when less than 50~40% due to an empty battery. For example, I restarted my phone a few minutes ago and upon booting it was 98% from full charge then I rebooted again and it's 78%.I'm not sure if this is a faulty battery or something wrong with the calibration. I tried calibrating multiple times but still nothing. I never abused my battery and most times I charged my phone before it hit 10-20%. Also one more question, I've noticed that on PureFusion the charging amperage was around 2-2.8 amps but on RR it reports 1.7 amps so is quick charge enabled on this ROM and if not what are the kernels I can flash to get QC? I've tried flashing Elemental X but it gets me stuck on the HTC splash screen.
I admit I'm kind of a noob when it comes to reporting bugs or issues, and I'm sorry for the length.
I'll add better screenshots of my stats after I collect more data.

I, and a lot of others, have suffered from the same symptoms. I thought I was alone but there is a big thread here https://forum.xda-developers.com/htc-10/help/random-shut-boot-loops-t3690547. I have got a support ticket (which is probably soon to expire, whoops!) but I've currently got it stuck in a bootloop at HTC (white) screen. Is this what yours did? Can you help me out?

No, my phone simply stays on the black screen with HTC logo in the center and the red text under it. Idk why it does that after flashing the kernel, probably not compatible idk,but what works with me is flashing the ROM again without messing with anything else.

Fixed mine, thanks. Just reflashed a stock rom I found on here. Wish I could help you more, but I think you might have to just return it unfortunately mate

I bought mine from another country and no international warranty so :/
I'd appreciate it if anyone replied to this thread. My phone is really unusable and disabling everything makes it useless and doesn't even save that much battery. My last resort would be to replace the battery but we all know how that would turn out and how it happens .
I tried :
1.Factory resets.
2.Flashed Viperrom,Leedroid,Purefusion 7.1.2,Resurrection Remix.
3.Flashed kernels like Cleanslate,Helix
4.Used battery saving apps like Greenify, Amplify, ForceDoze.
5.Disabled location, wifi, sync, cleared cache , reset app prefences, etc...
6.Started phone in safe mode.
Took all these steps and literally no significant improvement. I can't pinpoint an exact reason as to why I'm getting this drain but I noticed a lot of usage in GSam made by Android OS and in BBS and Wakelock detector PowerManagerService.Wakelocks seems to be on top of usage, and *launch* and *alarm* also have a very high number of wakelocks +1000 or even +10000. I've read on another thread that it might be wifi issue staying awake all the time. If someone has a good app to recommend me to monitor exactly and record whats draining I'll be eternally grateful .

Just a quick update.
I collected some stats. Not much but i saw some errors in there maybe some make some sense of them?
Mainly errors that are about Batterystats service: No controller energy info supplied and Power HAL : Failed to acquire lock whenever i touch the screen
I'll collect more logs and screenshots overnight in a +6hr period.

Hmm. That's weird because I had multiple ROMs installed and tested without any 3rd party apps like facebook and still get awful battery life. I'm back to stock now and will try deleting the fb app. Your stats are pretty good compared to mine.

Hmm. That's weird because I had multiple ROMs installed and tested without any 3rd party apps like facebook and still get awful battery life. I'm back to stock now and will try deleting the fb app. Your stats are pretty good compared to mine.
Thanks.

You are welcome , i hope it work for you too , because i have noticed that Facebook application have too much irregular activities while the screen is off and when it is on there is a lot CPU usage, so it must be there something wrong

I found no solution except a battery replacement i can say it was definitely the battery. However, the drain is somewhat higher than it should be on Oreo.

Glad I sold my HTC 10 and bought XA2. Way, way better

Battery Drain following Oreo Update, even after update to Oxygen OS Open Beta 5

I have a Oneplus 3 and I have been quite happy with it .. up until got notified for an update to Oreo a few daya ago.
Since the update, the battery drain on the phone has been pretty bad and even when I am not using the phone, the battery is draining much faster than it should or was.
Yesterday I tried searching on Oneplus forum to see how to fix it, and saw some post suggesting to update to Open Beta 31. I downloaded the update the manually updated the phone, and the battery drain still seems to be same.
Fyi, my phone is not rooted.
Please see the image below for battery drain graph..
What I can see is that even when the screen is off, and the wifi is inactive .. the phone is still awake and not seemingly going into deep sleep mode..!!
Can anybody please help how to solve this issue?
Thanks

you could try better battery stats although it is a root app to find what is keeping the phone awake, i think you can use adb to grant the permissions for it to work without root or you could factory reset that should sort it out

From the screenshot, I am able to see that you have a very patchy mobile signal which is one of the reasons for the drain .

Well, the signals have been same even before the update. The battery drain was not like this before.
In the last 8 hours, with little use the phone went to about 36%..
Now I can do a factory reset but it's an annoyance because all my data would get lost, or I'll have to backup and restore using some means.

I have noticed that with an incremental update, things get sour on OP3. The best bet without losing data would be to clean flash the full ROM after wiping system, data (excluding internal storage), Dalvik and cache. I am sure your issue would be gone.
I always clean flash and have no such issues.

100% App related. I am getting great battery life on Oreo 5.0.1 by using Greenify. Maybe 3-4% overnight.

Just because it worked before doesnt mean it will work the same after an update. Mainly with this OEM.

Hi,
I've tried clearing the cache and also deleting everything except personal data and reinstalled the update 31 multiple times. Still the same problem.
The battery is draining at about 10% every hour regardless.
Can anyone advise what else can i try?
My only doubt now is if the update 31 file is the right one to install. I'm assuming that because the file is approximately 1.5GB it is a full update rather than a incremental update.
If that's not the case, can anyone tell me which file to install as the full update?
Another problem I have noted since the update is that the Camera does not work. Not sure why though.
If nothing else works, I'd be forced to try and downgrade to android 7 though I'd prefer to have android 8 - if it works and does not drain the battery this much.

You say that you have the OP3 but the heading of this thread refers to Open Beta 5 and then you say that you clean flashed Open Beta 31. Which is correct, OP3 or OP3T, OB5 or OB31? No wonder you are facing issues.

Hi
The phone is Oneplus 3
It prompted for auto update to Oreo, which I did.
Then started battery drain issues.
After reading forums, I updated to Open Beta 31.
The battery drain is still there and I have reinstalled Open Beta 31 couple of times which includes deleting everything from the phone excluding personal data, music etc.
I have cleared cache as well.

I repeat, your mobile signal is one, if not the only, heavy drainer.
Install BBS, grant permissions through adb, run it and take an idle dump (as described in its thread) and attach it in the BBS thread. Someone there will study it and identify the culprit/s.

I've installed Bbs and here's what it shows:

It shows something named video2 is keeping the phone awake most of the time. I also found that the phone cpu is awake most of the time rather than being in deep sleep.
Looking on the internet, I can't find what video2 is!!
Any ideas?

Also just found that the YouTube app is also not working. I google'd and found many people have reported the same problem, and have been suggested to do a factory reset. So I've just done that as well and it has still not helped.

Here's another screenshot of betterbatterystat showing the same issue :

This shows that the phone is not going into deep sleep most of the time, as video2 is keeping it awake. Hence the battery drain.
Any ideas of what I can do to solve this please?

Tried a reboot? Don't use any force dozing apps or block wakelocks.

Yes, rebooted the phone and I am not using any app to restrict wakelocks or force dozing any apps - apart from what's inbuilt in the Oreo os.

It's known that Mobile Data can be a really big drainer. I easily go from 0.6% per hour on WiFi to +2% on mobile data, especially poor signal as you have shown can drain even more. You could try using Greenify with Shallow Hibernation, it doesn't kill apps it only restricts them from doing too much in the background, you could try blocking the wakelock with Bluspark's build in wakelock blocker. But I am highly against blocking things that you don't know (Can cause more wakelocks, random reboots etc).

If Video2 is similar to Video3 is then most likely camera related.
Maybe some app is using your camera and doesn't even let your device sleep. Which could make sense since even being awake all the time 10%/h drain is way to high with the screen off, so probably other hardware is being used.
Check your apps, you might even have malware installed. See what permissions was each app.
I'd recommend to backup your data, do a factory reset or even wipe system partition (although you need TWRP for that
Since you mention that YT is not working another possible option is that is some playback video related.
Same thing, backup and factory reset. Install each app with Playstore and don't restore backups.
Maybe when you backup your data into your PC run some kind of Virus Scan over all the file just to be safe.

Android 11 update - serious battery drain issue

Hello,
2 weeks after Android 11 update, my pixel 2 xl started to feel hot and the battery was discharging quickly. On Google help, many people were in my case, and many of them mentioned about unstalling Tunein. Which I did, then my phone stopped to be warm but this didn't stop the drain issue. What I have noticed is that if I don't touch my phone, the battery acts as normal, slow discharge, but when I use it, meaning when the screen is on, the battery just discharges at a crazy speed. It was not like that just before the Android 11 update. Anyone got this problem and found the reason / a fix ?
Thanks

I am having the same issue. An have not found a solution as of yet. I thought it may be the Pixel Launcher. So I changed it to Nova Launcher with no change.

Yes, strange. Mine gets a serious battery drain from 100% to 50% in a short time, even when I don't use it. Then below 50% it is very stable as long as I don't use it. Never experienced this before.

I have the same problem. before that, I was calmly getting 4-6h SOT After updating to Android 11 as lucky as I get 4h SOT. Mostly, however, I have 2.5-3.5 hours. The standby time seems ok, Only during use the battery disappears very fast. ? In my free time I will try the factory reset.

I think i got it...
Hello gentlemen, i got this problem with october update in particular.
So, digging in a google forum i found a user who recommended to install an updated version of Android System Webview (maybe you should download it from apkpure or apkmirror) , Carrier Services and.... uninstall Tune-in (yep... the radio app)
I don't know which one did the trick... but it just did..
I hope it helps!

Can you comment which versions of carrier services and webview you installed?

Sure, i installed webview 86.04240 and (there was a mistake in my prev post) Device Health Services 1.17.0.331553323.
Anyway, i got 2 webview updates since then... so, just install the last one... if you got auto-updates enable you should have your problem fixed by now (i guess that happened to the op).

thanks for the info, unfortunately I checked and I have exactly the same version of the application installed. the problem with the battery remains. the strangest thing is that I have no problem with idle drain, but when used with the screen on, the phone uses almost twice as much energy as before ?

I have the same problem, idle drain is ok, but whenever I use the phone, the battery drains very fast.

finally someone with the same problem. did you do factory reset before updating to Android 11? Because I don't, and I think I'll try to do it.

NO, i didn't do a factory reset because I have seen a lot of people (online) doing it without success. You can see this thread here on Google support, over than 580 comments today...https://support.google.com/pixelphone/thread/70445129?hl=en
But apparently some people fixed the problem with a factory reset...

I had the same problem and it was a new (at least to me) Google program called "Digital Wellbeing". I had to turn it off, which wasn't a straight forward proposition. I even "uninstalled" which just uninstalled the updates and they came back.
I don't recall exactly all the steps I took, but I now have my trusty Pixel 2 XL back to it's previous battery usage. Which is excellent for a three year old device.
Anyway, turn it off, take away all it's permissions, and do everything you can to shut it down. I was almost ready to root my device just to really get rid of it.

I disabled digital wellbeing, stopped the permissions, and uninstalled the update on the play store, but it didn't fix the battery drain...

A few days have passed and I can see a significant improvement. Honestly, I don't know what actually helped. some app update or maybe something I did, but there's a significant improvement.
In general, I would like to remind that from the update to android 11 my battery was tragic but only when using it, there was no problem with standby.
I was barely able to get 4 SOT hours. Now I can safely exceed 6 hours.
The only modifications I made were:
- leave beta program of digital welbing and its complete shutdown app
- disabled wifi scanning
- disabled Location service for emergency calls ELS
Since then, battery consumption with the screen on has dropped from 25-30%/ h to 12-16%/h. The phone is like new again. In addition, everything works very quickly and smoothly. ??
