Recently I have noticed on several occasions that my phone have gotten hot and started eating away the battery. One time I had around 30% battery and the phone was laying in my pocket. I felt the heat through the pockets and took it up to see what's up. It then had 0% battery and turned itself off.
When looking at battery use in settings, it's hard to pick out one specific application that might do this. If anything it would have to be "Android system", right now it's tied with the screen on 40%, but I charged the phone an hour ago and I haven't used the screen much.
Edit: I should add that the same thing just happened, from 99% to 89% then it stopped. That's why the information above about battery usage is relevant.
Do you think it might be hardware-related, like a partial short circuit or something, or is it most likely a software thing?
Bump. 10 signs.
Had mine for a few days, have not experienced anything like what you describe
I have though felt the screen get hot when turned on full brightness and reading a e-book on it (white - black text)
Well this is while it's laying in my pocket, with the screen off, so it's not the screen. (it's the battery that gets hot)
Take it back.
[Funny story that probably isn't relevant. I had a dodgy micro sd card that made my phone drain battery super fast and as a result my phone got incredibly hot. Took it out and it's back to normal.]
Sounds software related to me, your android system should definitely not be 40% of your battery. It sounds like some rogue app/process is utilizing your cpu and thus your battery very heavily. If you select the "Android system" in the battery usage list, does it not give you a further breakdown of what is included in that that is using your battery? Also, what does it say for the cpu time for the android system?
May be firmware bug
I've had this happen to me a few times when I was running the original firmware. In some early firmware there was a bug related to switching between wifi and 3G, which would get it stuck so that you couldn't toggle wifi on or off. The times this happened to me, it was also stuck in the wifi bug (although I had the wifi bug and it didn't drain the battery).
I now run the newer firmware (JG4) and both problems have stopped.
I've had this problem with my asian i9000 since the beginning. The app called Top showed me that it is ksoftirq/d that is running and System Panel showed me that the cpu was running at 100% at 1ghz.
At first the only solution seemed to be restarting the phone. However some information shared on this forum led me to try restarting wifi which also works. For that thread search for "ksoftirq/d."

I have had the "stuck wifi" bug, but I'm not sure if it was happening the last time this happened. I'll check it out the next time.
There's no official firmware update on Kies for Norway yet, so I think I'll wait for one.
Had exactly the same problem and tracked the culprit - it was Fancy widget in my case. Removed it, installed Beautiful widget and all is well since
Sent from my GT-I9000 using XDA App
That might actually be it. If I'm not mistaken Fancy Widget had 30% battery consumption when I checked. I deleted it just to see if it would make a difference. So far so good.
Some details:
Fancy Widget will hit the 100% cpu on auto-refresh if there's no data connection available (either wifi or cellular). It seems there are 2 bugs with Fancy Widget; it ignores "auto-refresh off" option and it tries to connect to server even when offline.
A dirty work around would be to set refresh time to let's say 12 hours and make sure to manually refresh at least once every
That makes me even more convinced that Fancy Widget is the culprit. I usually have cellular network disabled (APNDroid On/Off Widget) to save battery and my wifi connection keeps loosing connection, probably due to some software bug in XXJF3 stock firmware.
CASE CLOSED!!! Please read bottom part or flash stock GB 2.3.4!
I have posted this already on another thread (almost word for word) but I just really want you guys know and not panic about this problem and avoid going through difficult fixes like deleting system apps, recalibrating battery or even resetting your phone.
Since JVK was released, many observed that Android OS sometimes get hungry and devours battery. For some reason it is triggered to go berserk. Others say that the main culprit is the Auto update app. But other apps like Google Maps, Latitude and even just in a place where there is very low network signal or Wifi reception could also trigger this problem.
Now, I have a very simple solution: Turn off device, remove battery for a minute, put it back then turn it ON. Yes it is just that simple, REBOOT YOUR DEVICE.
Yeah after you turn on your device Android OS is still on the top of the list with high percentage but I believe it is just as it is because it previously consumed a lot of battery. All you have to do is observe again for an hour if your battery is dropping again, look into the graph and see if it is still steeping to the bottom. If it is dropping like Mt Everest, do the procedure above again.
If not, you will observe that after a couple of hours Android OS's percentage is getting low. Problem is fixed, (temporarily though).
Why go through deleting apps, recalibrate battery etc when you could just turn off your device for a minute?
I have experienced it a lot of times already (one of the first users who upgraded to JVK) but it doesn't bother me anymore. Turning off then on your device is very simple ain't it?
I highly advise that you do not touch anything on the sensitive part of your phone as there is no known single root of this problem. Just like I told you, many situations or apps could trigger Android OS to go berserk. Until there is no definite solution to this problem, I suggest you do the above procedure and save yourself from going through the pain of removing system apps, battery calibration or even hard reset.
By the way my battery usually lasts 3-4 days unless I made Android OS angry again.
INVESTIGATION
INVESTIGATION CLOSED!!! The culprit is caught. But the fix is not so simple. Only Samsung and genius devs (apparently the fix requires closed source modification) could fix this. If the problem occurs on your device, just do the temporary fix above. Please do not try to mess with your device for now.It is now fixed in XXJVP 2.3.4!

All this is due to Tatsuya who pointed us to the right direction. A big thanks to him for helping us in this investigation. CASE CLOSED

Ok thanks for the credits.
This previous link I gave explains how you can use watchdog to alert you when this bug triggers, so you know when to reboot your phone to stop this leakage (if you really want to stay on gingerbread until a fix is made by Samsung).

Guys if you want to help out please please please dial this *#*#4636#*#* and check "Usage Statistics" and let us know the top 3 items on the list! (highly suggested by {Angel}).
Below are some of the possible culprits currently pointed out by some users (I will update the list based from your feedback):
1. Software Update service
2. Google Maps
3. Latitude
4. Low network signal
5. Very low WIFI reception
6. Auto updates in Market
If this helps, a simple thanks is enough

Those of you with high drain, you can also check battery history through *#*#4636#*#* and see what you have under other usage 'running' and see if your phone as not been sleeping lately. I get this occasionaly with froyo and I suspect many people do also. A reboot fixes it for me, after that my battery usage is superb, but it's annoying as hell.

Yes just like I said in the first post, this is just a temporary fix. But I think users should just do this rather than touch anything on their phone unless they really know the source of the problem.
That is why I suggested that they report what could be the possible triggers, like apps or situations, that make Android OS to awake and gobble up the battery. If we could just pinpoint those triggers maybe we can now figure out the root of the problem. Your fix of removing a system app, the auto update app, is not even the single source of the problem. We just do not know if that app is an essential app or not. Sooner or later you will have that problem again.
I am not saying we should just sit and wait. All I am saying is if you are a plain user and you do not know the exact root of the problem, then just do what I suggested. But if you are a dev and is exploring the root of the problem, then do as you like and we will be most thankful if you find out the answer.

Rebooting works, and it seems to be working until you start some apps again. I have the same apps installed as I had on JPY, but JVB drains my battery dead in half a day.

Could you pinpoint some apps? I will update the OP to keep track of possible culprits so that others will avoid triggering this problem. Thanks!
I once saw that the battery drain from 95% to 9% after one night, and the android os used most of it. I rebooted my phone, and the problem has gone away, since. Happy with Gingerbread!
I'll give it a go! thnx
Active Widgets: WeatherBug Elite, 3G Watchdog, BatStat and Calendar.
Apps: All from above plus Twitter, Titanium Backup, Facebook, Twitter, Tapatalk, Camera360 Ultimate, Root Explorer, Foursquare.
Mostly I use the Twitter client and the browser. Location services are disabled.
It is hard to figure out from the above apps or which is the most probable suspect. Just incase the problem recurs on your phone, dial this: *#*#4636#*#*, Go to Usage statistics and Battery Information and please report back (include also information on the Battery Use in Settings).
I hope we can help others avoid having this problem until there is a fixed solution.
Thanks!
Did what you suggested and pulled the battery at 30% waited 5 minutes and put it back in.... 1hr later it was at 35% (WTF!) and 30min later it was at 38% (WTF!)
im assuming its recalibrating?
Not necessarily. Maybe the battery meter is anticipating the fast consumption rate of Android OS that is why when it got fixed, the meter is able to readjust the readings based from the current consumption rate of your phone. Good to know it helped
Maybe use the 'forbidden' task killer? Works for me... Maybe im imagening it but works.
Btw my battery goes quickly down after getting below 25%. My battery not calibrated? Should i.calibrate it? I have this program to do it but am afraid that calibration goes wrong. (example what if my battery is 95% and will calibrate to 100. What if.i charge my battery higher than this.. Will it show 104%? Or will android stop working for it cannot be displayed in the notificationbar.
Using cm7.
Sent from my HTC Desire using XDA App
You do not have to recalibrate. Cm7 has a known issue about battery. I think you cannot charge past 94 or 95 percent and battery usage is a bit terrible. Please refer to cm7 thread for possible fixes, (the last time I checked their thread, they say it is probably kernel related).
Just turning off, pulling the battery and turning on does do a lot for me! i went from 10% per hour to only 1%! great thnx!
Hi,
About battery drain in gb, once fixed the wifi sleep policy issue ( by setting it to "never") u shouldn't have batt drain, but i've installed green power ( juice defender do the work too i think) to get some wifi management possibility back and it improuved my batt life.
But never the less, my battery won't last more than one day of hard usage ( being hanged on xda all day long, for instance ;-)

Guys, just turn off the task killer, it helped in my case. looks like its not working well on ginger
Rebooting works just temporarily.
It will come back the next day or so.
This is not a solution at all tbh.

Guys, on Gingerbread I've had battery drain two times:
1. Had about 14% drain in 3 hours all of a sudden, without doing anything at all. Just started going down for some reason.
2. This morning, saw about 40% drain in 7 hours..
And, both time I solved it by Clearing Memory from the Task Manager.. Went back to normal 2-3% drain per 6-7 hours after that..
So this might also be a solution. Go to Task Manager, RAM tab, and Clear Memory..
i'm on ginger also and my battery acts weird. 2 days ago i charged my phone over night while it was closed. the battery holds for 15 hours with massive use.
last night i did it again, but today it went from 98% to 80% in about an hour !
this is really weird.

Did you manage to check first what is running on your device by looking into Battery Usage settings? I think you have a case of rogue application running in the background.
If you have not rebooted yet could you please attach a screenshot of the battery usage list and graph? In that way we might possibly identify the app running prior to the clearing of memory. Thanks!
Hi,
Reading the thread of Jamal's Google Play Edition 4.4 ROM, i noticed some users were saying they could get 4 hours of screen on time. Sadly enough this wasn't the case for me, and I think many other users can confirm. On a full charge, i can barely get 2hours of screen on time out of it, which is of course unacceptable. I decided to analyse the battery usage.
What I've got after a full discharge is illustrated in the attachment. If you know how I used my phone during this period, the curve is very surprising and hard to explain. The first hours I had my 4G on for extended periods and I noticed pretty decent battery life, i.e. 25% gone after 1 hour of screen on time. That's surely an acceptable score and would give me also that beautiful 4 hours. But suddenly, the phone made a weird change. You can see that the phone starts discharging much faster with a new and constant slope. I tried stopping it but it didn't change at all. My 4G and wifi were all set to off, even my location settings were turned off. Nothing changed.
I started searching the web if some applications were not optimised for android 4.4 yet, but didn't find anything significant. But then I found topics about the Exchange issue which already gave many android 4.4 users headaches. I read about a constant error-looping that could cause fast battery drain and, sneaky enough, doesn't start immediately when the phone boots but can start after a period of several hours. I decided to shut the whole thing off and deleted my Exchange account. Rebooted the phone and the issue was gone.
Hopefully a fix will be brought out soon!
Hi all,
Having just bought a Yotaphone 2, latest model 801 processor and with Lollipop installed, I was impressed with it... lovely screen, sharp response, great display on the back ....until I realised that battery life on the EPD or indeed doing nothing was (and is) terrible.
This somewhat negates the point of having the EPD. Because whether you use the EPD or not, as others have found, the processor seems to be spending 100% of the time doing something like trying to connect to Google headquarters to report my unethical swearwords as I look at the battery level heading south.
To try and make sure the phone was using the least power, I went through all the running apps and services and terminated as many as I could, turned off things like Yotafit tracking, turned off the service that sends all your contact details to the Kremlin, and so on... then, I turned on the Yotaenergy mode and despite that, we are at less than 24 hours with virtually no phone usage at all. Fully 50% of all the energy according to the battery stats is being used by Android System and Android OS processes when the system is in standby. And the historic battery screenshot shows that the processor is active 100% of the time., even though the phone has not been touched. (sorry, not attached, I'll post at some point, but its not very interesting)
So, does anyone have any clues about how this can be fixed? I have seen screenshots where people have shown that their processors are not active the whole time, and I imagine they have Lollipop? I have heard Lollipop has got some kind of bug which means that data connections are live the whole time, not sure if this is related.
(This might explain the sudden appearance of half price devices on eBay around six months after launch in the UK.)
Many thanks in advance!
YotaDevices has acknowledged the problems on Lollipop battery life, which is the reason they won't be shipping devices coming to USA preinstalled with Lollipop, but with KitKat. Now that I've played around with the EPD and created some widgets/applications for it, I can spot many places where things can go wrong in maintaining battery life and still keep things working.
Personally I've been lucky with the battery life on all versions of Android. When I updated to the last version of Lollipop (firmware 1.44), the phone did show poor battery life for hours after the installation was finished, before calming down to the promised 5 days stand by. Are you on the very last firmware? (Settings - about phone - build number)
As a last resort if your device won't settle down, I guess you could roll back to Kitkat, which had a very good battery life for pretty much everyone. You can install it with Yota's flasher tool: ftp://fw.ydevices.com/YotaPhone2/YotaPhoneFlasher/yotaphone2_flasher.exe
Just carefully select your own region and then the last version of KitKat (4.4.3) they offer. As you are rolling back from one major version to another, I would suggest flashing pretty much everything. You will lose your data.
Yota has said that they are working on bringing Lollipop 5.1 or 5.2 to Yotaphone 2. Let's hope that that works better.
Thanks that was very useful. The question is, will Yota do another build ... or build another device? I'm hoping the Y2 has a bit of life left in it yet and they do launch in the US - it can only help the development community!
I reset back to factory/Lollipop last night as it was eating battery so fast I could not believe it, and I am on the latest build 1.44EU (and was before). Since then.. it doesn't seem to be misbehaving so much, but it does seem to insist that the WIFI is on (when it is switched 'off' in the settings) by 'on' I mean the battery usage recorder... I wil take your advice and 'take it slow' for now, but may flash back to Kitkat if necessary. It is a bit tedious having to reinstall all your apps by hand but this seems to be the only way to ensure it is relatively clean.
The screengrabs below show the phone doing nothing at all in Yotaenergy mode - per first post.

I am quite confident that they will release updated Lollipop sooner or later. They don't have the resources to piss off all their customers just yet.
Your Wifi still does some scans on its own for Google's location service, even if it's not enabled. You can disable this feature in the advanced wifi settings. But that is not the cause of your battery problem. Basically your device is awake all the time, meaning something is holding a wake lock. And by something I mean one of Yota's EPD compoments, which are counted as part of "Android OS" and "Android System" - your biggest battery hogs. It could be one of the EPD widgets that is misbehaving, or it could be some specific combination of them, or just something out of your control.
You could try removing ALL the widgets from the rear screen from Yotahub, then restart the device, and then let it run for an hour with the screen off. Then check the detailed battery log if the device went to sleep or if it was awake. If it went to sleep, you can try adding widgets back one at a time, and then check again if the device sleeps. Basically all the widgets which update periodically hold a wake lock momentarily (time, battery, calendar, weather etc). Of course if the problem lies on Yota's EPD framework, then this wont help at all.

Agreed, I suspect the YotaFit app going bonkers despite my efforts to kill it.... or the Yotagram service, the thing is, looking at the Yota specific apps, you don't really need them, as you can flip the screen with the Yotamirror, and then use any Android app. Sure it would be nice to have notifications on the EPD, but my main focus for this phone is use in bright daylight, and long battery life, not to actually look at the thing 24x7 so I can respond to emails every 30 seconds.
At this point though I'm just trying to determine how bad the underlying hardware is. The GPS on this phone seems to a bit flaky, as does the basic reception of mobile signal. (And I'm not using a metal bumper.) So, I'm happy to flash back to KitKat 4.4.3 to try and give it the best chance..
So, any clues/links about the Yota flash tool? I've put the phone into USB debug mode, installed the flash tool on my windows 7 desktop, and installed ADB/Fastboot as well, but at this point I'm having a bit of an android driver problem, and ADB can't see the phone so that probably explains why the Flashtool says 'waiting for device' when I fire it up. I will go digging to fix that, but I assume that the Flashtool will do all the stuff like putting the phone into bootloader mode, unlock etc...

The widgets I'm running at the moment without any problems are Time, Mini Calendar, weather, battery, and communications (the small widget which shows phone calls, notifications and sms). And of course my own widget.
The best way to make sure there are no useless services running is to root the device and uninstall them completely, but that's another story.
For the flashtool to detect the device, you need to boot it into download mode manually. The easiest way is to turn off your device and plug the usb in while holding volume down -button. The screen will show "download" or something in very small white text. After that the flashtool should find the device. You probably don't have to flash the user partition (it asks for it separately), i.e. the simulated sdcard section which holds all your photos, documents and music.
Edit. And when you have kitkat installed, the first thing you might want to do is to disable automatic system updates. Otherwise it will nag you about the Lollipop update all the time.
I've been facing similar issues and am considering a downgrade when I have the time. I'm really disappointed in yota and won't be buying their next device.
I have found this thread useful, you may too.

thanks gents, oddly, the advice to let the phone 'calm down' seems to be working. I decided not to revert to KitKat (yet), as every day I use the phone the battery life seems to improve. Yesterday it was down to 40%, today 60% after about a days use. I'm thinking a week of running in will give it time to stabilize. I would love to root the phone but I want to use the Good app, and that doesn't run on rooted phones... (shame but I guess that's the flipside of working for a big corporate for you!)

Try putting the battery widget on your epd. If it shows 5 days remaining when you are above 85% and you don't use the phone, then the device works as advertised.
That Good app sounds like a real killjoy. There seems to exist some Xposed modules to disable the root check, but they seemed to be rather finicky to setup and very easy to mess up.
I was suffering from terrible battery life after the lollipop upgrade and the EPD battery widget was never showing much above 1d anymore. After much research and tinkering, it has now improved and I am seeing greater than 3d again. I think the culprits were maybe google fit tracking which I have now turned off and I also de-installed and re-installed the google play services updates which is a tip I saw in an android forum. I also over the last two days have received several yota widget updates which may have also helped. At least for now I am seeing a comfortable day's use again!
I experienced poor battery life out of blue again. I went through all the settings, cleared dalvik-cache and cache partition, tried disabling everything, but nothing helped. It only showed <1 day battery life at 100%.
But then I went to mess around in the developer settings, and when I set the animation scales from 1x to 0.25x and enabled "Force GPU rendering", the battery life returned instantly to 5 days.
Just thought I'd add this to the list of things to test out if someone's experiencing poor battery life. The forced GPU rendering might have some unexpected effects on some software rendering based games.
dont know if this will help but just seen some of the new features of android m "marshmallow" one of which is doze and there is a separate app available on play store for this. i have installed and it has helped battery life !!!
I was going through terrible battery life after Lollipop as well. Suffered, tinkered, tried various things. Eventually I just said screw it, backed everything up and factory reset it from recovery. Since then it seems like it's almost back to it's old self. Obviously having root and using some kernel control apps, greenify and some other things helps it but It will happily do at least a couple of days with little-normal usage. Still don't think it's as good as KitKat but it's not too far off. The EPD really does help spread battery out too.
I did the same thing but a 3 weeks on, the battery is as shocking as ever.
Today, on battery since 0730, now @ 1115 51% and 3hrs left!??
No obvious apps causing battery drain, just google services!

I think it is something with Android 5.0 that is causing the drain issues. I can go anywhere from half a day to a week with good batteyr life and then it will randomly start draining again. Some background activity seems to hold a permanent wakelock and will not let go of it. I am unable to pinpoint what app is creating the wakelock with better battery stats or wakelock detector since there isn't access to kernel wakelocks in either of the apps for our phone. A restart always fixes things though, so I have a tasker script now that lets me know when idle battery drain exceeds a threshold for too long so I know to do a restart, it's not elegant, but my battery life is exponentially better and gives me enough battery life to make it through the day without a recharge and leave the eink screen on all night as a tv remote.
I got a new phone

I am unable to pinpoint what app is creating the wakelock with better battery stats or wakelock detector since there isn't access to kernel wakelocks in either of the apps for our phone. A restart always fixes things though, so I have a tasker script now that lets me know when idle battery drain exceeds a threshold for too long so I know to do a restart, it's not elegant, but my battery life is exponentially better and gives me enough battery life to make it through the day without a recharge and leave the eink screen on all night as a tv remote.

In the end, I got a new phone after my Yotaphone decided to brick itself. Its a Zopo Speed 7, Octacore, dual SIM, nice screen, and does 4G very well in my part of the world. It is also around $200 at time of writing. Its a Chinese phone typical of the genre, Zopo seem to be moderately responsive to bugs compared with Yota... This Zopa phone is running 5.1 Android and I can tell you that Lollipop is not the problem...
That's after charging the phone and leaving it overnight, with the battery saver mode on... not too shabby. Of course it won't actually last 28 days, but this phone is nothing special and it is capable of running without all those services running that the Yota has.
The Yota spent its entire time when I had it trying to contact Moscow with that dodgy 'dictionary app'. What (honestly) is the point of the e-ink display if it doesn't save power...
If you are experiencing "always awake" and wifi always on despite your settings saying otherwise it may be worth going into your advanced wifi settings and changing "wifi frequency band" from "auto" to "2.4 GHz only. I remember reading this tip somewhere else for an Android 5.0 phone that was having battery issues similar to this. I made this change about 24 hours ago and have noticed a dramatic difference in battery drain when the screen is off. When I look at my battery stats I am no longer seeing a solid bar for both wifi and awake. Worth trying.
For what it's worth, I have had fairly light use today, some checking of emails and facebook, 40 mins or so of music via bluetooth (with screen off). Total screen on time of 35 mins. The phone has been off charge since 06:30 this morning. It is now 17:00 and is showing battery of 71% with an estimated 2d and 8h left. Better battery stats show deep sleep of 71% whereas previously it had shown awake at 100%. Far better than I had before.

Have you tried using the setting so Wifi is only on while screen is on? (Unless on charge...)
I think I found the issue, at least with my phone.
I was syncing with exchange, and there is a nasty bug with android 5.0 and exchange sync. The sync is taking forever and doesn´t sync everything. Calendar and contacts missing.
Then I removed the ActiveSync connection on my phone and set up the app Nine to sync instead.
After that I got much better battery. This may help for others as well. The phone is just hammering the exchange server all the time and this takes up a lot of power.
Hello all,
So I know there's various discussions all over the web about the Galaxy s10 and battery issues on both Snapdragon and Exynos variants. It seems people are experiencing a wide margin of difference in avg battery life..
So here's my situation. My wife and I both have S10+'s through AT&T. We got them the first week they came out. I looked though the forums and performed several battery optimization tweaks on both phones and since then the battery life has been really impressive... No complaints really. Until this last week.
We both recieved the March security patch and fingerprint scanner fix about a week ago. My wife's phone seems unchanged by this. Everything working as expected. My phone however has been draining battery MUCH faster both in SOT and standby time. I'm losing 2-3x more battery % overnight. In the last 20 mins of just reading through threads on the XDA forum app, I've lost about 10% battery. I'm sitting in the dark with my screen brightness very low too. (down another 5% since I started typing this!)
My wife and I have very similar phone habits. Since both our phones are optimized identically, and we used most of the same apps a play the same games, I started looking through everything different I've done in my phone since this problem started. I installed Adhell3, which seems to be setup properly and working. Mike B. from Adhell's Discord assured me that Adhell shouldn't be draining my battery. I'm mostly using it just to remove a bunch of basic bloatware and block some ads.
The update seems to have worked fine otherwise. My FP scanner is much better now, but something is definitely wrong. I've tried wiping the partition cache afterwards. I've tracked down others experiencing issues after this particular update, but cant seem to find a way to fix this problem yet. I saw something about Deep Sleep problems after the update when someone uses a VOIP service like Skype or WhatsApp, but I dont use anything like that. I can't even find a good tool to use to see more information about my battery usage, as the built-in battery monitor lacks a good deal of information. CPUspy doesn't work on my version.
If anyone has any ideas of what could be the culprit, what else I could try, or what tools I could use to try and track down what exactly is causing this sudden increase in drain, I'd really appreciate it.
Which update do you have ASBA or ASCA? This is rather weird, Battery drain can also come from restoring from backups. I lose 2% every night and my phone is on airplane mode, not connected to anything except location. I do not have adhell, and last time I tested before the fingerprint update I had 10h SoT on wifi purely. When I got the new fingerprint update I checked if the phone went to deep sleep and it does, so I really do not know what might be your issue. I have an exynos variant btw. Also I charge my phone constantly from 80 I let it drop to 40 and charge it back, I do not use fast charging options. Since unplugging my phone now on LTE fully I have lost 1% in 30 min, I have my fitbit always connected, location on, max resolution, I have a semi black wallpaper and brightness around 40-50%.
I will see today how much SoT I can get from 80% part wifi, part LTE, I will update.
clear cache helped a lot of people
Update 1
Reset all phone settings to factory. Don't do full factory reset, just all the settings, fixed my post update battery drain issues

Update 2
Hrrm. It seems I don't have ASBA or ASCA, I have ASD3. The March update.
I'm really hoping I don't end up having to factory reset and manually install everything... Because I did do a restore from backup with AT&T Transfer, because it seemed really convenient and time saving. I had no idea that so many people have had issues with restoring from various back up services (AT&T, Samsung, Google etc.)
I did the same restore from backup on my wife's S10+ too and she's had no problems. Her battery life is phenomenal. My battery issues only started after this last update.

Well that seems rather strange to be honest, you can eliminate possibilities by just testing and see what works. Last possibility can be that factory resetting and installing all new, but then again, it could be that it solves your issues or not. You should be having rather horizontal lines to prove your phone is truly going into deep sleep in my opinion, but also you can check with CPU Spy
Sorry it will be this pic
Try to log too safe mode and check the battery drain
If stopped then it was from an application that have a problem
If not I think it might be a system app or something
So. I'm starting to think that some of my problem has to do with wakelocks. Unfortunately I have limited access to wakelocks statistics since my phone is unrooted. However. Last night I fully charged my phone right before bed and then took it off the charger to see how much it would lose overnight. It dropped a whopping 10% vs the 1-2% it used to.
I looked through some of the battery info and noticed several apps running in the background for very long periods of time since last night. Chrome(2hrs) , Discord(2hrs), Google Play Services(a whopping 13hrs 30mins running in background) and Google Play store (5hrs)
Somehow Discord was responsible for draining 7.6% battery in that time!
So, could this be a wakelock issue causing my phone to lose so much battery overnight? I know that's only half the problem, because I'm also experiencing higher drain than usual while using certain apps too. But I'm trying to figure out one thing at time.

You can look at this thread and see if you can install the app without being root or not

You just need to tweak your settings more, put which apps do not run on the background or go to sleep, how many days you need to wait to put unused apps to sleep. Is all tweaking the settings.

Then I don't what you can do, either do a factory reset and so not restore anything from backups and see if that works. I usually set my phone that way, clean no restoration from any backup all apps are installed manually, and I do not even use adhell to disable most of Samsung crap apps and services.
