Frustrating Battery Situation. Let's figure it out! help??

I never had a good battery on this phone since I bought it (second hand)
my average SoT is about 2hrs for around 15h uptime daily
I formatted many times trying to fix it, changed roms, kernels, governors, interactive profiles. nothing worked
I thought it was the battery. so I changed it by myself and it's the same, or even worse than before (lol)
Yesterday I removed my google account to see if I have too many services running. and still have 25% active drain and 3% idle (ex kernel manager stats). too much
I don't know what to do now.
1) someone suggested me to watch wakelocks but I need help on that because I don't know how exactly and what look for
2) do you think that could actually be the device? is it possible that lg could accept it as defective? I don't think so. they should be able to repeat my issue, and we know that isn't possible since battery usage is very personal
3) do you have any configuration you suggest me to try.....? maybe I'm missing something
Thank you for your attention, I hope that this thread will be useful for everyone

Personally, that's just about right for me. I think I get about the same SOT if I had light usage. Usually though I get 3-3.5 hours SOT with around 12 hours off the charger. I top off for an hour on the charger once a day everyday and just got used to it. A lot of times if people have longer​ uptimes, doze was working overnight​.

Have you tried to flash it back to the stock nexus image? (Return it entirely to stock) That would be my first step in nailing down battery issues. It will completely wipe your device, but it rebuilds all the partitions and updates everything to the newest images. (Assuming you've downloaded the newest release from google). Then you can run it on pure stock for a few days and monitor it. My n5x isn't the greatest either with battery, and standby drain is brutal on nougat no matter how you configure it, but I usually get at least 4 hours of sot. It also depends what you have running. If you're using bluetooth and location services, google assistant ect, it follows the battery is going to drain much quicker. If you flash the stock image, you need adb and fastboot installed. There's lots of guides here on XDA.

@throcker, my advice: try a ROM, stock or PureNexusc, clean flashed, without GApps, any Sync off, GPS and mob data off. You should get 5-7h SOT.

I wiped completely several times, downgrading to 6.0, updating via ota, flashing lastest image, with and without encryption
I use bluetooth (g watch)
I'm very experienced on flashing and stuff, tried everything by myself, this thread is a desperate thing

You all wanna know what's going on now?
battery 23%
Google play services 18%
whatsapp 11%
screen 10% (1,12h)
and I don't even have google account.

@throcker: GPlay-services means, you flashed GApps. They are busy in the background without account.

oh $#!T.
but...I'm really bounded with google services stuff, I sync my pc chrome, keep, docs, maps....
I think I'll give this a try, but there is no way I could run that setup as my daily.....

Same here and I don't really know what to do... Really frustrating and I don't even have BT, NFC and GPS toggled on!

Use BettetBatteryStats to check for wakelocks during the night to see if something is keeping the phone awake. Then I also recommend either unplugging the phone from the charger right before going to bed or setting a custom reference point to check how much the phone drains during idle. I had the problem that my phone was draining about 2.5%/h in idle even with nothing installed, airplane mode, everything off and so on. This turned out to be a hardware problem which could only be fixed by replacing the motherboard. So check if you have the same symptoms that I did.

Battery Drain

Ever since I updated to 8.1.0 with December security patch, I've noticed my battery draining faster than normal. I was getting 4-5 hours of SOT with around 45-50% battery left. This was after being off the charger for 12-16 hours. Now I'm getting about half the SOT at similar numbers. Anyone have any ideas?

Excuse my stating the obvious, but you need to find what process or app is using the battery. You should be able to get a rough idea just using the new features under Settings>>Battery. It will identify which apps are using the most juice. Run the phone in Safe Mode to see if your battery life goes back to normal. It could also be a service like Google Play Service which sometimes wigs out and starts chewing battery. Are you rooted? If you need more detailed information there are battery drain apps available to help isolate the problem (BBS and GSam). These apps require root to give the best results.

Not rooted and currently locked. I've downloaded GSAM and have adb permissions and it simply says things like Chrome, RCS Phone and Play services. If you see from the photos below you can see what I'm talking about. Chrome currently isn't that bad, but yesterday and the past couple days it's been like 9% or more of the battery.

Two things: I've never seen phone or kernel use that much battery. On one page phone usage is 33 seconds, yet it used 9% ? I think RCS is running the background all the time. See if you can toggle it to not run in the background under Settings>>Apps>. High kernel I'm guessing is a kernel wakelock or multiple. You've probably loaded app(s) that are creating the problem, but you need to find out which one is causing the wakelocks. There is a wakelock detector "lite" app that doesn't need root but I don't know how well it works. I know the root version works well. Lastly, on the first screenshot with the battery, scroll to the bottom of the page and see which apps are listed there. I'd be willing to bet if you ran the phone in Safe Mode, your battery drain would disappear, meaning your user apps are causing it.

Well in safe mode my drain is gone so I'm not sure which app is doing it, but to directly answer your question about the RCS it is an overall app meaning it is related to several Google play services. I'll upload a photo of it. I have to reboot into normal mode.
Edit: I'm wrong about that it was the play services.. I'll have to start uninstalling the apps to determine which one is draining the battery I guess.

RCS can be a real battery hog, but I don't know why. I don't have RCS on AT&T. Do you use Messages as your primary SMS? Open Settings>>Advanced and see if you can toggle off "Enhanced Features". Open properties and check if it is using battery optimization. If it is not, set Messages to battery optimization. You can always turn these back on later if the battery drain remains.

My battery life has been restored to pretty much the same as it was with 8.0. I also noticed poor battery life after installing the 8.1 update, even though they changed the way battery life is estimated with this update (supposedly). Something just felt off, but now everything feels great! I am fairly certain what changed is installing the Greenify Magisk module and/or the Google play services doze module (this enables battery optimization on the Google play services app). Not sure which one really made the difference because I installed them at the same time. However, there is definitely a major difference!!

In my experience that's really good.
Before 8.1 I noticed about 11% per hour during screen on use and about 0.33% per hour while on stand by in my pocket or a little bit better if it's just sitting on my night stand not moving while I'm sleeping (I think doze is more extreme in that situation) which seems to match what you are getting. Based on that screen shot I think that's like 8 hours screen on time over like 35 hours for a full charge. I've done a little bit better but not much. That's excellent battery life.
Since 8.1 it has dropped. Best now is maybe 7 to MAYBE 7.5 hours over maybe 26-28 hours. In my experience battery life always drops after an update but this case is far from the worst. I remember when my Nexus 5 updated from KitKat to Lollipop. The battery drop was awful and to make matters worse the battery life of the Nexus 5 was pretty bad to begin with.

So in my last reply I thought I was wrong about RCS Phone app being a conglomerate of several apps in the phone. For some reason I couldn't find the information I needed at that time. I wiped my phone and started over after posting this thread. I was trying to isolate the misbehaving app. I thought it might have been greenify actually, but no the drain has returned to a lesser extent though. Here's some photos of this RCS app from GSAM.

I'm not sure what is causing the drain at this point. I've installed Better Battery Stats to locate the wakelocks so I can ignore them through ADB.

Have you tried disabling RCS ? (Post #6). BBS is good for idle drain, active drain not so much. It's best run overnight without touching the phone for 8 hours or so. Pick the phone up in the morning and create/save a log file as quickly as possible. Post the log to the BBS thread if you need help deciphering.

Anyway to stop this horrendous battery drain?

I'm not sure on this one....you have to have an app somewhere that is killing your battery. My phone normally gets almost a day and a half easily. With Wifi and bluetooth constantly on, watching YouTube videos, and even screen sharing to my TV. Go through your Apps and find the culprit that is killing your battery.

go back to stock, watch drain for a couple hours install an app, rinse and repeat until you find the culprit.

Here, personalization service uses the GPS the most, but I don't know all the related Samsung apps that depends on it.

Same problem here, i dont use too much my phone, not gaming, not videos, just social Network and the telephone dont reach the 5 1/2 hrs screen time, most of the time is on standby, the WORST battery of all my phones in years.

Those with battery drain issue, are you guys using the Exynos version? Mine is Exynos and the battery drain is crazy since day one

Try this, it doubled battery life for me, especially since I spend the majority of my time connected to WiFi.

I'm using the Exynos version and not noticing abusive battery drain.

wifi will off mobile

technically, when you connect to WIFI, mobile data will not be used.
Except you turned on the use Mobile Data if Wifi connection or signal is slow/weak option

I had the same problem... Multiple factory resets and setups later, same problem. Was ready to return the phone because System was using WAY more battery than Display and I was averaging 2.5-3 hours SOT to 5% battery. Found someone suggest Bixby problems in another thread, disabled all Bixby related apps and now battery drain is gone, regularly getting 7-8 hours SOT with no problems.

One interesting thig I see in you first(high use) screen shot is the amount of battery used by adguard, where as in the subsequent image it doesn't even show up.

Because all traffic runs through adguard, battery stats are skewed when running it. It tells you this when you first activate it. I wasn't using it when trying to isolate my battery troubles, but I'm back to using it 24/7 and still get 7-8 hours SOT, so it wasn't the cause.

Bixby Voice Wake-Up was a huge drainer for me. Find it in apps, doesn't show up on battery stats page, but when you pull up app stats, it'll show how much battery it's used since last charge and for me it was crazy high.

This phone has had the best battery life by far of any I've owned. I'm on the US version unlocked straight from Samsung, using on T-Mobile network. Use it all day at work, been at work playing games and making fantasy football moves on my phone all morning for the past 6 hours and am still at 75% (and my battery widget that uses the system algorithm says I still have 14 hours remaining at my current usage level), and I use Always On Display on ALL THE TIME. Has to be related to an app or something. I will say though that I installed sideActions and disabled all the Bixby packages (along with several other Samsung-specific packages) since day 1 using CCSWE App Manager. I'm not a light user, either - I have Nova Launcher, several KWGT dynamic widgets, Tasker, AutoInput, etc...
Do ensure you have battery optimization turned on.

Disabling those Bixby apps helped a bit with my drain.

Excessive idle drain

So for the past 2 days my idle drain has been well over 2% with it currently sitting at about 4%. This is confirmed using ex manager. Previously my idle drain was less than 1%. Usually hovering at about 0.8%.
I find this very curious. Upon inspecting what's using battery I see nothing out of the ordinary. I cannot use bbs as I am not unlocked or rooted. My usage had been consistent, I have not installed any new apps. I don't get it.
Anyone experiencing anything similar? I guess if not and it's not some new temporary google play services thing my next step would be a factory reset.
Thane a million for your input.

I would start by rebooting into safe mode to see if this is reproducible. If not, then its a user app causing it. Did you add or update any lately? What build are you on and how did you get to it? As cool as I think the OTA process is I never fully trust it and always end up going back and "clean flashing" the OTA later.
Now, to be fair, this is the longest Ive ever been on stock in my life so ymmv.

I will give that a go. Thanks got the advise.
I have taken app updates as they become available. Not sure. Probably 15-20 apps have updated in the heat few days.
I am in the latest ota. I was on beta and updated to stable when it became available and then another update within the last week or so. Never saw a changeling for that one since it mirrored the Android 10 stable update.
I feel you on not running stock. This is the first device I have not felt the need to screw with. Usually that's step one. Unlock and root access. Saw you are working on a rom. I may give that a go when you get it up and running. I've run your stuff before. Solid.

Yea more times than not it's an app causing an issue.

Do you have always on display enabled? I found leaving that enabled definitely brings my idle way higher than I'd like it to go. With it off my idle is about 0.30%/hr on it can get up to like 5%/hr.

Yeah I've had that on though. It doesn't explain the discrepancy. I did a factory reset and am back to standard idle drain if about 0.7-0.8%. Thanks for the suggestion. I really appreciate it

Hi,
which apps do you use to check the drain in percentage?

I found that 4G standby (even without data switched off) started to drain faster when I travel. For example 6-7% during my 45 mins commute to work.
Strange is that battery usage app shown .. nothing that ate 7%, actually showing ... nothing.
No idea if this ia due to latest android but for sure I get less screen time 10 out of 11 hours.
Is it needful to download the image and flash or factory reset will do similar job?

I just used the factory reset option and it fixed my issue. Make sure you backup all your data. After that Google has made resetting the device extremely easy. Back in the day I had to jump thorough a ton more hoops when setting up. Now data is backed up as are password and login credentials. You'll be back up and running within 20 minutes. Good luck.

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 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.

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. ??
