Huge battery drain problem - Galaxy S8 - Samsung Galaxy S8 Questions and Answers

Hi,
I tried to find this exact problem, but not. I have serious problems with battery on my unlocked european Galaxy S8.
First I just tried some basic stuff like clearing the cache, diagnostics of Google services and so on. Then I installed BBS and GSAM, but nothing serious here. I monitored it like three days very often. Only thing that havnt made me any sense, is Android OS (something to do with kernel). It had more drain, than screen.
Second I tried some apps that I was suspicious to. Google Fit, Chrome, Facebook,... Nothing.
Okay, I tried Safe mode and even factory reset and nothing. So I was that angry, that I paid that much money for something, that even doesnt work properly, that I ordered a repair (they came to my home, took my S8, rent me another one and than after week or so they returned it).
I finally thought that it was bad piece, because they found the issue and swap daughterboard, charging cirquits, battery and reflashed OS. I didnt used Smart Switch or Google restore. I manually installed all my apps and I think, that battery drain started after I launched preinstalled Chrome. So of course I immediately disabled it, but battery drain didnt stop.
Now I was on vacation on place, where is like one bar of 4G or no signal, nothing else. In that place, battery was dying very fast. I turned on airplane mode and guess...
With my usual drain that Iam trying to figure out, I have about 2-3 hours of SOT only checking mails and browsing web with Spotify. With airplane mode on I played movie at evening. I had 89% after 2h of continuous playing HD movie with airplane mode. After I disabled it, battery started dying fast again.
I could not figure out, what is causing this, because in GSAM, BBS and setting is only "Android OS" and nothing more suspicious. I tried to turn off WiFi and Bluetooth scanning even when they are off, but nothing.
There is all my apps that I have installed in my S8:
Google Drive, Duo, Photos, Play Movies and TV, MS Excel, OneDrive, Power Pint, Skype, Word, Samsung Email, Galaxy Apps, Internet, My files, Samsung Connect, Samsung Gear, Samsung Health, Smart Switch, Voice recorder, 4G switcher, Adblock Plus for Samsung Internet, Airbnb, Google Analytics, Android Auto, Apshalt 8, Bakalari (my school app), Boldbeast recorder PRO, Calculator, Calendar, Camera, Clash of CLans, Clock, COntacts, CPU-Z, CZC.cz (app for local IT eshop), eBay, ES File explorer Pro, Facebook, Flixbus, Flud, Gallery, Gmail, Golf Clash, Google, Google Trips, Hangouts, Google Home, IDOS (czech app for time tables of trains and buses), Instagram, IP Tools, Google Keep, Letuška.cz (app for buying airplane tickets), Google Maps, Mapy.cz (local maps app), Messages, Messenger, MX Player, My Vodafone, NaVlak (another app for timetables wih widget, thats always synchronized ony my screen), Phone, Play Games, Play Music, Play Store, QRbot, Samsung Members, SD Maid Pro, Settings, SledovaniTV (app for watching TV online), UniCredit Smart Banking, Speedtest, Spotify, Steam, Strava.cz (school app for ordering meals), Stream (local youtube), Tenda WiFi, Tik-App, Translate, Trello, Wifi Analyzer, Wifi File transfer Pro, YouTube, Zaslat.cz (local app for ordering couriers to deliver packages).
Could you guys pleas give me some advices? I even tried disable Always On display, but nothing. Iam very shattered about this. At least we know, that it is software related issue, not hardware.
Thank you very much guys and sorry for my bad english skills
EDIT: It is caused by SW 1000%, because I experienced same issue on rented S8 when mine was at warranty repair.

you said it yourself..
it uses a lot more power when you have a weaker signal.

Hi, yes. It was worser, but I also had here my Nexus 6 and he was fine and chilling with one bar wo/ amy problems.
But with my S8, I have this problems in city wjere I live too. Amd there is everywhere full bars of coverage of 4G+ as my S8 says. Something is wrong. Usually at city I habe 2-3 hours SOT of light usage, on that vacation I could have maxfor example 1-1,5h. That was only worse.
I tried running 24 hours without any sync (I disabled it on status bar toolbox) and nothing change, so synchronizing isnt the cause aswell. It must be some app or bad settings or I dont know what else.
Thank you.

I get 6 hours of SOT and 1 day+ usage using an S8+ with AOD on, WiFi and more apps than you do.
Ask for a replacement / battery swap.

Please, there is milion threads about great battery life. I know that it have And as I said, they completely changed battery, charging cirquits and USB-C connector. And with airplane mode there is no battery drain. So I suppose, that it couldnt be HW related issue.

Try switching wallpaper and themes to black. The phone consumes less energy then

Greenify put unused and background apps to hibernate. I think it's worth a try. I used to have the same problem as u. After few days using Greenify, my batter is getting better.

I tried to Greenify suggested apps, but nothing. I tried AnTuTu Battery test (4% one) and Ive got 12800 points. I have problem with SOT, where percentage is dropping hard, but also sleep, there is big drain, but like 10% a night in well coveraged area. Could anyone help? I dont want to return this good device... But Iam also very angry, that I must deal with this sh*t...
Thank you.

Do a factory reset once more and try not to install ANY apps for at least 2-3 charges. Be in a good coverage area. After a couple of days, install your key apps and use it for another 2-3 charges. Finally install all your apps and check. As a side note, also check your standby time with and without data connectivity when you do not have any apps installed.

Install a app that watches for Wakelocks.
I suggest you this app: https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats
I've used it many times and sometimes it can give useful information about something draining too much battery (While the screen is off).

Yes. I did this research. All I can see in those apps is drain by Android OS (no more accurate) and it stops with turning on airplane mode.
I tried Greenify almost every app to try, but nothing.
I dont have much time to do factory resets and setup my phone again and again. Iam trying to research it as deep as I can with yours help. If it will be neccesary, Ill do third factory res.

I will instal that monitoring app once again and then put screenshots in here.

No panic....something is bruning your battery and preventing your phone entering deep sleep....
Install betterbattery stats and post pics or wakelogs as mentioned before.....
Hint:i had similar issues back with s7... it was corrupted media file i had on sd card.... phone was trying to scan system and files in loop while connected to network.....any chance that you have sd memory external card with full of music? We will know more after your screenshots from bbs app.
Best of luck

Kernel wakelocks
Okay, I used it for while with permitted GSAm and these kernel wakelocks are very strange...
Grip sensor I dont know, but the umts is very interesting. It has to be something that is draining, because wo/ sim or airplane mode it is running perfectly fine. I read something about it and it is maybe caused because unsupported modem for my network, but I purchased it in here in official Samsung brand shop and yes, on the package is European SIM only. Which I have. My friend will try it and if he will have this problems, I will sent it to warranty again or my SIM card is maybe faulty.

Just install package disabler pro on play store. disable bloatware and applications that you dont need

Icant see any reason soing it. I want it sctock and running fine. These advices arent solution. There is problem in something else and I want to research what. There are mmc0 and umts wakelocks, but biggest wakelock is in some app that I could not figure out.

Does package disabler pro really help with the battery?

Evo's battery life is quite good, if you know what the problem is.

So my wife and I both have Evo's. Both of them running DamageControl's ROM. My battery life will be down to about 45% (or less) after about 4-7 hours. Hers will be between 94-97%. This is with not really using the phone except to answer a call or two. Everything is turned on, WiFi, GPS, Bluetooth, Sync, GPS location, etc. All the social and Sprint apps have been removed except for Sprint Navigation. No CPU controlling tools are running, such as SetCPU or OverclockWidget. Though Advanced Task Manager was running in the background to kills apps every 30 minutes, but I don't think that had much of a bearing on it.
At first I though my battery was defective. It was nuts that her phone was lasting so long and mine was being sucked dry. She wouldn't let me take the battery out of her phone to test, so I started looking at what the differences are between our phones. The only main difference between our phones is the number of apps installed.
So based on that guess, I used Titanium Backup to backup all my apps, then proceeded to remove just about all the apps on my phone. Especially any app that might use the network. Though I left wireless tether as that was installed on her phone as well.
I charged up the phone to 100%, left it unplugged overnight, and after seven hours, it still had 98% charge left. So it was an app(s) that ended up killing my battery life. Now I'm using Titanium Backup to start restoring a few apps at a time until I can find out which apps that are causing the large battery drain.
Very good read. I'll be trying this out as well.

Like Google said at their I/O conference, "if you can't get a day out of your android device then something is wrong with it".
Wow - sounds like a great experiment. Eagerly awaiting your findings.

There's an app called Systempanel. Even the free version will tell you in an instant how much cpu each running process has been using since it was loaded into memory.
I also use it as a task manager. Since it doesn't need to be running in the background like some other popular task managers.
Added back about 60% of my apps and still have excellent battery life. Only lost 3% over last night while sleeping. I mostly concentrated on adding back apps that shouldn't access the network. I'll start adding a few apps back that might access the network and let you know the results.
My battery last over 30 hours.
Here's the proof. I also had 50% battery left.

can you let us know what apps you're running and what was re-installed and what has been re-installed as yet.
One thing that EVERYONE should do before they even begin to evaluate their battery performance is CALIBRATE THEIR BATTERY!!
Can't stress it enough, it's crucial.
And fwiw I've found beautiful widgets to be a battery hog whether you're using it or not
we should create a wiki data base of the apps on gdocs.

Exactly. We need a wiki for everything on the evo (battery, apps, ect.)
I get about 8 hours of normal usage (texting a little bit, an hour of phone calls, some camera time and streaming music for 2 hours), but as soon as I get a good replacement, I'm going to flash up a good rom.

I have had less than impressive battery life on my evo as well. I am using baked snack .7 rom which is supposed to have excellent bat life.
Looking at that list the OP posted of apps he hasn't re-installed, i am seeing that we have 4 common apks...Astro, Square, Fring and The Weather Channel.
I have a feeling it may be TWC that is eating battery...I will try uninstalling this and Fring.
I also notice that he has several live wallpapers. Having checked systempanel, the only thing that is really pushing CPUs is live wallpaper. I am also going to disable that for now.

Please keep us updated. I'm interested to hear your findings.
I use Damage also. I get good battery life. In a stock configuration, there is still one massive battery drainer on my phone, 4G. I turn that on, and battery power drops like a rock.
I had 4G on in the office. (The area around the building is 4G, but not inside. ) I had an almost full battery at 10am and 50% by 12:15pm.
FYI, I do have the radio patch installed too with Damage 3.2.
ChrisDos, this is an excellent thing that you are doing. Sometime soon, by adding an app or two at a time, you'll find the battery assassins. I appreciate you doing this, and look forward to your discoveries, especially since my phone is rooted yet. It will be wonderful to know in advance what the main culprit or culprits are so I can ditch them.
I'm basically in stock, as-shipped configuration, and with light usage I'm getting maybe 6-8 hours, less if I am active on the phone, and we know that I'm not alone.
Now we just need one of the slick developers figure out how to root the Evo in such a manner that it can be restored 100% original and undetectable. My brother can do that on his phone, don't recall the model and don't know how its done, but could be very handy in the event of a warranty issue.
Thanks again, ChrisDos!
I'm not trying to hijack the thread into a "show your battery usage" thread, but I... I... I thought that it might be useful and-- Anyways, I'm on the stock (1.32.651.1) rom from flipz; haven't found a rom that really caught my attention yet. I'm not a media whore, but this snapshot is after 3.5 hours of usage that consists of phone calls, vpn access, wireless access, gps, remote desktop, text messages, emails, web browsing, and a lot of music. Screen was taken at 44% battery life according to Spare Parts.
Thank you for doing this!

Dude.......that...is...awesome.
I've had no luck with battery. I've been playing Battery Nazi the past few days and still no luck. Three different ROMS, killing stuff every hour, only turning on the network radio when I need it...it's like being in a jail cell with a barred window that opens to a mini golf course and go-kart track. Every thing I want to do is within reach, but I just feel trapped!

[Q] Android OS high battery use, no apparent wake locks

All of a sudden, my battery life went from awesome to crap like it does from time to time after something gets updated. At first the culprit was Google Play Services so I started hacking away services and receivers using 3C Toolbox which made the problem worse. So I backed up all my user apps that I use, wiped, and re-installed PA 6/20 build with the latest pico GApps. Google Play services had a good wakelock on the system so I disabled the SystemUpdateActiveReceiver and SystemUpdateSecretReceiver with AutoRunManager (SystemUpdateReceiver was already disabled). That solved the Google Play services wakelock but now I am left with Android OS crushing my battery, but no listed wake locks. CPU Spy reports a few seconds of deep sleep, if any. Here is some info from Battery and WLD. These were taken after I charged 100% before bed, and had most of my user apps frozen with Root App Delete, wifi, data, and location off.

See or it's maybe related to google play services, click on it and see if there are maybe any related things. If you are going to return your phone for this reason then I don't get you cause this is just a awesome phone. Try to maybe do a factory reset if nothing works.

My phone still says it's awake all the time and Google play services is using the Lions share of my battery, however I am getting about 2 days out of my battery like I used to before this problem. It's annoying, but I don't think it's that bad. You can try disabling those 2 receivers with auto run manager like I did but if your battery is even worse after that I would just re-enable them and leave it.

The phone was bought off as the last one on the store. Worten, in Portugal. So it was a demo phone. I have no idea, for how long the phone was plugged in to the charger, being demo'ed. I am afraid the batttery has lost some of it's power. Nonetheless, i will use it for a few days and then return it for warranty if i don't think it's in prime condition...
Also, i had an HTC HD2 with custom rom, then moved to a Galaxy S2 with a custom rom as well (AOSP 4.4.2 with Cyanogen) and now i am using the stock LG rom. I can't say exactly that it sucks, but for sure i prefer the stock AOSP experience with the right tweeks.
Well, a patently I got 6:55, and 33 hours of phone usage on my first experience with the car phone. I used 3g, wife, and web browsing. I don't know if it's good, but I highly doubt it...

I've noticed this phone has hit or miss battery life depending on what you have installed, greenified and frozen. I thought it would be a good idea to create a thread where everyone could share their battery life tips and tricks on this phone.
Below I posted what I have done to maximize battery life. I have not rooted my phone yet, so none of the below tips require root.
I disabled all bloatware apps that came with the phone. I did not disable any of the Asus applications.
I utilize the Asus autostart manger and denied auto start to all my applications except music applications, messenger applications, and google photo sync.
battery sucks. drain to much.
Just use until you have 5% free battery, this should make at least your day
With Android OS taking so much thanks to lollipop, there is not a lot to hope.
We wont see a good battery improvement until we get 5.1
Luckily, that is in the future for this device acc. to Asus.
Since the issue seems to primarily be Android os draining the battery I don't think most battery saving measures will make a difference. We will just have to wait for an update
When I was looking at the phone reviews people were claiming 8 hours screen on time, I can barely get 2 hours screen on time.
The problem I'm having is that the phone never goes to sleep and is constantly awake. Has anyone else seen this issue?

I had the same problem after the latest update, no deepsleep in BetterBatteryStats (I'm rooted), I wiped everything and now it goes to deepsleep.

Which firmware version are you on. I've wiped the phone once already, did you clear any caches? It's driving me mad

I'm on 2.18.40.12 (ZE551ML of course), I restored the phone from backup & restore in settings (It may take 30 minutes or more). Before restoring I had 45+% of Android OS during the night, now 20% more or less, but, as said, also in BBS I can see deepsleep in frequencies.
Someone posted on Zentalk to turn off remote lock and scan for security threats in google settings. Not sure if it helps or not.

I wiped my phone yesterday and restored back up like you suggested and it seams to have sorted out my wake lock issue. I wonder why that is?

Glad you solved, but don't know why, maybe they are working hard on the firmware and there are lot of changes that can cause problem, maybe we have to wipe after every update, Intel processor and Lollipop are so unstable right now!

Ok so this is my battery with a normal day of use... Tomorrow ill show the results with your sugestions. My normal days have gsm calls(normal phone calls) whasapp (chat) youtube, twich, game like plant vs zombies 2, look at gmail, surfing internet, taking pics like 25 today.
I notice that battery drains a lot more while photo app open.
I use doble sim as you can see
If you want to test app battery drain, try GSAM Battery Monitor, or for some extra functionality the Pro version. Also very useful to determine what is causing wakelocks when you run into them.

Thank u sir thats a good one
Everyone is always wondering about Android using the most battery. Without doing some in depth debugging and tracing I would guess Houdini falls under Android. Because the ZenFone 2 uses the Intel processor a binary conversion for ARM instructions takes place with Houdini. More than likely you have a lot of apps native for ARM.
Force closing asus support app and zenui services app from apps setting gives me good amount of battery boost. Apart I have also disabled google books, movies, plus etc. I don't know if its placebo effect but someone can try and confirm. These app tend to restart at times so if you feel the battery decreasing at high rates again, make sure you force close them again.
Roughly speaking, I tend to get 3-5 min per percentage of screen on time with this which totals to 5 to 6 hrs on SOT on continous usage. Without the apps being force closed, I barely get 2min/%. The usage scenarios are normal web browsing, chats etc. This is using mobile data. It gets even better with wifi.
Try and let me know if this helps.
Maybe I don't use my phone as much as other people. I posted this last night on another forum. My phone was unplugged at 07:00, It's now 21:00. I have 80% battery left and the battery monitor shows 3 days left
I have received email, 3 phone calls and text messages. I checked Twitter a couple of times with the browser. I have read Google News a couple of times and played GSN Casino for about 20 minutes.
In Auto Start Manager I turned off Docs, Sheets, Skype, Slides, Translate, Amazon Kindle, Data Transfer and Web Storage. Everything else is Allow, but I have no social networking applications installed.
Its looks like battery life is a right mixed bag. At the start of the week I was suffering wake lock issue, my phone wouldn't go into deep sleep and was constantly awake. I wiped and restored from backup which seams to fix the issue.
Got up this morning and it looks like the wake lock issue is back. I don't know what to do to fix it.
Feel like giving up on the phone and sending it back if I can

BUGS & BATTERY USAGE on JULY official rom

hi MI A1 owners.
for those brave enough to use the latest vanilla, official OTA rom, what change did you notice?
does the battery still suffer huge drain that appeared in 2018 roms?
it's a big "NOPE" for me to update, i'm still on official DEC rom because of this drain issue.
Battery life is good on 8.1 no issue for me getting 5-6 hours SOT on gaming.
Never had battery drain problems. Only "issue" is notification led not blinking.
Just noticed that led light is no longer blinking when notifications arrive. Light stays on only when screen is off. Also Bluetooth is constantly disconnecting.
Ambient display isn't working for me.
Led notifier is also not blinking anymore!
Led not blinking, proximity sensor doesn't work properly all the time, some scrolling lag. That's what I've got so far
dudes thanks for your answers.
i'm just more convinced to not doing the update.
maybe the drain i had was magisk-related. (?)
Nothing for me, even got ten hours of screen after some cycles. Led doesn't bother me and it's the only thing i noticed.
Yes, the LED is always on, which is annoying, but the bigger issue is there is no change in the battery drain. I charged to 100%, set the phone down and did not move it or use it overnight. 8 hours later almost 14% of battery was drained. I have tried everything I can think of to try, including turning off high accuracy location, not allowing any location things like safe area, etc. and still I get this drain even when the phone is not in use. Android kernel and system consumed 85% of that usage, and System UI, Play Store and Phone Services accounted for 7%! SO basically, basic Android paired with the A1 hardware seems to be the issue and I don't know that there is any fix for that.
At one point, I thought an upgrade to the A2 was going to be a no brainer, but with the issues with updates being broken and this battery drain issue that nobody seems to be able to pinpoint and resolve, I am thinking I may not buy ANY other Xiaomi. It may be time to try something else because the only way I can get two days of battery is to turn on airplane mode when the phone is not in use!

Dunno what to say man. Mine is below.
2-3% at most over night.
And now it would appear that there is an issue with airplane mode.
I put the phone into Airplane mode at 2300 last night with 90% battery and did not pay attention to it. This morning I turned to phone on to find there was only 69% battery left, and WiFi was working. (see screen shot) WTF???? I have started using airplane mode to keep the battery drain to a minimum when the phone is not in use, and now it would appear that this doesn't work either.
I am REALLY getting frustrated with Android and Xiaomi as it seems that every time they do an update, something else goes bump! I have gone from totally happy with the AI when I first got it to being ready to write off Xiaomi as a company I would consider for purchase.

Is your WiFi scanning is on. ( Under location / scanning)
Play services also cause these type of sudden battery losses.
Try downloading latest play services apk from apkmirror . Latest one is
"com.google.android.gms_12.8.74_(090408-204998136)-12874034_minAPI26(arm64-v8a,armeabi-v7a)(480dpi)_apkmirror.com.apk"
Uninstall your current one. Install this .
Power off your phone for a few seconds and reboot.

Thanks for the thoughts, but unless I totally misunderstand what airplane mode is, WiFi should not be active when airplane mode is invoked. You can see by the screen cap that airplane mode is on AND WiFi is active. This seems to be a one off as it has not happened again for the last two days. I turn airplane mode on to stop the overnight battery drain while the phone is doing nothing. I have location set to GPS Only. IIRC play services was just updated 3 days or so ago, so it should have the latest version. I will check it and see though. Again, thanks for the thoughts.

I can't logically understand why you would think it is the hardware causing the issue. If it was hardware, what you are seeing would be happening to every owner of the phone and clearly that is not happening. By saying it is the hardware when you have other software loaded is akin to saying your car's air conditioning doesn't work properly when you have all the windows wound down.
There is something loaded on your phone that is causing the systemUI to be working when you think nothing should be happening. The first thing I see on the screenshot on your phone is that in the top left of the screen you have two non standard icons. That tells me that you have a skin or non standard software constantly running.
The way to solve any issue like this is to go back to basics. I would get the fresh rom and do a Miflash whilst keeping your data. Make sure you do a backup first.
If that does not work, back up your data and do a clean install and check the phone's battery life. Do not load any non google software / app at this stage.
Then each day add one app and test for 24 hours. You will find this issue and the offending app or apps and I would be willing to bet you a few Singhas it will be an app you downloaded not the hardware causing this.

Actually, I think it is a combination of hardware/software, but that is just a WAG. Others have noted the exact same issue without running the same software. My bet would be on the RCS services stuff.

Those icons are my Email client and GSAM Battery Monitor (presently 0.1% and 0.8%) and are the only two constantly running programs other than the stock apps and Sophos (0.3%). Neither use much battery compared to the Android stuff. Presently Kernel is 41.6%, RCS/Phone is 30.3%. SystemUI is 3.3%, Play Services is 2.0% and Phone Services is 1.8%

Good advice. I will do this when I have a few days to play with it. In the interim, it's airplane mode every night. Thanks for the reply. If it turns out to be one of these apps, let me know where to send the Singhas.
Good luck with it. I hope you find the solution. It can be frustrating, but getting to the bottom of it will be worthwhile. I haven't used Sophos for a long time and even then it was for PC. I am not up with how Sophos AV is integrating into Android but that would be my first guess.
I have only had one issue with this phone after updating and it was that the OS was constantly asking for a password on unlock after using fingerprint not just on startup. A clean install solved it and I have been trouble free since with every update. With over 50 PCs in my office, I could only wish that I had so few issues with Windows updates as I do with Android.
For me, night light auto schedule not working properly.
I can't tether via wifi/bluetoth/usb
Made another post with the problem.

Just for grins and giggles, I uninstalled my email client, GSAM, and Sophos, the only programs that run constantly other than system and Line. I then turned my phone off and back on, forced stopped Line, charged it to 100% and set it down with the screen off. It did not move of get used for 8 hours, yet it still used 12% of the battery. (see screenshots) This is better than the 20% with those apps installed, but still not close to what I would consider normal. When I first got the phone, it easily lasted 2-3 days between charges, with 6-7 hours SoT. Overnight would use MAYBE 2% of the battery. Now if I want it to last 2 days I need to turn on airplane mode overnight and then I can make it through a day.
So I guess the next step is to do as you recommended and load up the fresh rom when I have time to mess with it. At least I am now pretty sure that those apps aren't the culprits causing the biggest part of the battery drain. I hate to do it, but I am seriously thinking of a factory reset and seeing if that clears the issue. Would that put me back to Nougat?

How do you disable this apk? I seriously think this is the major culprit in the battery drain.

So those apps were causing 40% of of the 20% of the battery drain. That is a good start. I am confident there are software issues with your phone. I see you have some GPS app on your home screen, if that was running askew, it might be constantly pinging. That is just a guess.
In things like this, work methodically through it. But of cause a hard reset would be the best way to go. I see no reason why you wouldn't stay on your current version after a hard reset.
If you want to go make to version 7 you would need to use the MiFlash program and a downloaded standard fastboot rom. You may need to do something else to the phone to go back to 7, but I would not think so.

[Q] S10+ Excessive Battery Drain

Hey all,
Recently got my S10+ replaced under insurance (dropped it about 10 stories), and have since rooted it (magisk).
I get a crazy amount of battery drain, up to 35% an hour when using spotify (and Viper4Android). I get high CPU alerts constantly from google play services, even overnight when charging and not touching at all. Device runs very very hot too.
Just want to ask whether anyone else has had this problem before taking it back and asking for a new phone. Seems like a faulty phone but don't want to rule out a bad flash
Cheerio
I suppose bthat you are rooted, since using viper... Use battery stats to se exactly what is the problem, is it kernel or app related... Either ways, good quick start would be cash clear from recovery and network reset... If still draining, force stop than delete data for gplay, services and google framework this will log you out

I'd feel pretty stupid if I rooted a phone and then considered taking it back because of battery drain. I don't know how anyone could say it seems like a faulty phone when they apparently immediately rooted it without testing the battery life. I'd suggest learning how to use a phone before rooting it and then claiming the sky is falling. Unbelievable.

I've had rooted Android phones for the better part of 10 years. I also had the same problem BEFORE rooting, and flashed a custom OS to ensure the battery drain wasn't due to bloatware. In addition, if you read my post properly you would have noted that this is only an issue with a replaced S10, and was never a problem with the original S10, which means I am completely aware of battery usage life.
Keep your useless and misinformed comments to yourself.

Yeah this problem is old as Android itself the way i dealt with it in the past is i used betterbatterystats app overnight let it record who and what is sucking the battery dry. In your case it seems google services framework is the problem (surprise surprise)
If i was in your shoes i would try what @Sparkynis suggested first, clear cache and data it will delete your google account restart the phone wipe cache in recovery and add your account again if the problem is still there then you might have an app that refuses to go to sleep
and it will show up in betterbatterystats. If that fails i would wipe everything start from scratch only adding your google account not installing any apps besides the betterbatterystats to see if it's the google services framework messed up or an app you have installed that is forcing a wakelock somehow.

Thanks mate, did the battery stat's and it's the location alarm triggering a couple of times a second. Have reformatted and flashed multiple times and yet to fix the problem. Leaving location services off, however, does solve the problem.
This workaround works fine until I get my s20 but unfortunately I was not able to find the root cause. Faulty gps chip maybe? No idea.

Try looking into Google Maps that app triggers location services ALOT even when not running, i have the Unlocked s10+ U1 and even i notice the same thing with Location off i lose 2% of battery overnight with it left on i lose about 9%
Do uninstall google maps and let me know if it's the same. Also i used to have an app called wakelock detector full i haven't used it since my gf bought me the s10+ last version i have is 2.0.4 last updated in 2017 lol but it helped me find apps and system services that are awake and using cpu alot maybe that will help you find the cause
