4.4.2 battery life is terrible - Nexus 7 (2013) General

Has anyone else noticed a decrease in battery life since the 4.4.2 patch?
At first it seemed comparable to 4.3 battery life: 6-7 hours of screen time with Chrome:The Battery Hog. It also didn't discharge AT ALL when idle. Maybe 1% overmight or so. That is with most programs set to sync hourly and wifi off when screen is off.
However, I've let it fully discharge one time from 100% to 0% battery. It turned off and i immediately put it on the charger. I cant remember if it was since then or a few charging cycles later (100%-15% ), but now it uses a lot when idling: around 5% per hour or so. Screen on time is also terrible. See screenshots for details.
Can you guys share your thoughts on this matter?

More than likely it is your Google Play Services that are killing your device. This issue has been occurring ever since 4.4.x

Is that fixable or do i have to wait for a new update?
Also, I remember that the battery drain started when i connected to a friends phone to tether via his phone over wifi. Does that have to do anything with it?

I cleared data on Google play services, and put my location settings to battery saving. The GPS on all the time drains the battery. With moderate use, I'll last about 10 hours.

You could use an application called Disable Service but it requires root access.

My video playback battery life have dropped significantly since I updated to from 4.3 to Kitkat
details can be found here
The following are using MX Player Pro, H/W+ Hardware acceleration, 720p videos( in 16:10 aspect ratio to fill the full screen). I seen no visible change between 4.4/4.4.1/4.4.2 AOSP in battery life.
Android 4.3(AOSP), Full brightness(15/15 or 583 nits), 6 hour 6 min for 86% or 14.1% per hour
Android 4.4(AOSP), Full brightness(15/15 or 583 nits), 5 hour 15 min for 86% or 16.4% per hour
Android 4.4.2 (DJLKang 4.4.2+ElementalX 2.5), Full brightness(15/15 or 583 nits), 5 hour 30 min for 86% or 15.6% per hour
Android 4.3, 2/3 brightness (10/15 or 389 nits), 8 hour 5 min for 86% or 10.6% per hour
Android 4.4.2, 2/3 brightness (10/15 or 389 nits), 7 hour 20 min for 86% or 11.7% per hour
Android 4.3, 1/3 brightness (5/15 or 194 nits),10 hour 41 min for 86% or 8.06% per hour
Android 4.4.2, 1/3 brightness (5/15 or 194 nits),10 hour 13 min for 86% or 8.4% per hour

I usually get 5 1/2 hours of on screen time max. Pretty annoying.

That's pretty normal if you are maxing your brightness all the way.

This is the battery time I got while using it for two days. Not bad in my opinion.

I keep my brightness almost all the way down. And I have location services, and always listening turned off.

Okay so ive had another cycle. Now, it drained 10% overnight. The screen on time seems okay but ive switched to art with this cycle, and ive seen people get 10+ hours with that.
Im going to try to delete google play services data as you suggested, but it doesnt use as much battery, as you can see in the screenshot.
Android system and Media server seem to use the most energy, though at the time of the screenshot, 80% of my screen on time was whilst using chrome. Also, theres this process called com.android.chrome:sandboxed_process4. What is that? I have googled it, but to no avail. Ive seem multiple imstances, ranging from 0 to 4, in my battery usage list.

I've kept my brightness nearly all the way down ever since I've owned this tablet. Anything above halfway gives me a headache.

Are you rooted on your device? You could use an application called Greenify and manage your processes.

Thank you for the information, but im no IT specialist. Could you decode the page for me and tell me in short what it does?

These are screenshots with the tablet idling. Ive let it rest for 8 hours straight, and havent opened any apps.
Seems like it drains 5% per 8 hours. Previously, it drained 0-1% overnight (also 8 hours). Seems like there is the problem.
Wifi seems to drain a lot too, even though i have the "Keep wifi on during sleep" setting set to never.

Yes, I am. Thanks. I will give it a try.

Or install app ops since you're rooted and disable keep awake for all android stuff, especially Google play services and Android system . For some reason Googles devs thinks drainage is less important than whatever they do but fortunately we can adjust their mistakes to our benefit. I get 3 days 10+h SOT. When the Google devs push out an update for something outside of play store "android OS" usually keeps awake until a reboot is made but luckily it doesn't happen too often.
And also, use a superior browser. I recommend Next or Dolphin.

At my age (15) I do not have much experience in developing/understanding how operating systems work but I'll try to explain it in a way that is understandable:
Android and pretty much any modern operating system has a way of "sandboxing" applications or programs. Basically picture a sandbox with sand in it. The sand cannot escape the sandbox because it is around that box. (This is where we actually get the term 'sandbox')
When Google was designing Android, they basically made an implementation into the system that reduces the frequency and impact of application security issues. With that being said, this was made so you can use the default file systems and such without harming the system itself. If you were modifying the system, you could potentially open your device to a exploit. The sandbox features come into play so it can isolate your application from other applications. If it wasn't like this, any application could execute code to steal data/code from other applications. You can still do this with exploits in the kernel and such, but it isn't as easy as it seems.
You may have heard of the software on Windows called Sandboxie which is designed to to prevent "permanent changes" changes to your system, files, etc. It basically separates the system from the application itself. It is commonly used to test to see if software that you have is infected. In short, this is similar to what Android has.
--
The site I linked you in my other post basically explains how Android creates these processes in a more technical manner. But that link was specifically for Google Chrome, but it can be pretty much used in any other application if needed.

I would suggest greenify and put everything but the system to sleep and see if that does it for you. If you unlock the bootloader, install TWRP, root and install a custom ROM on your tablet you can use a custom kernel and adjust (in layman's terms) the power your tablet consumes and when. You can remove some of the system apps you may not use and cut back on ROM usage too. Google adds all kinds of apps to the system that will function just fine as user apps.

[Q] Battery drain issue

Hi,
I got my second android phone (LG G2 obviously) this christmas, and I haven't had time to properly use it (I don't have a micro SIM yet). I noticed that my battery is going empty pretty fast, although I heard this phone has a amazing battery. My friend got this phone too and he told he's been on one charge for about 36 hours with constant wi-fi connection, app downloading, playing games etc. so I figured something's off. I charged the device before going to bed and when I woke up (10 hrs later) battery was on 85% (only 2 MINUTES of screen time!!!!) and I had no apps running on the backround, no nothing. So now I'm thinking is there some easy fix for this or should I return it and get a replacement? Also something weird I noticed yesterday was that even though I don't have a SIM card yet, but 16% of the battery was used by the phone application. I did some screenshots of battery usage today and yesterday too if anyone's interested.
There are literally dozens of similar threads... suggest you start searching.
And I literally have gone through 90% of them so I decided to start a new thead. Do you (or someone) think that a factory reset could help? And the next question might sound stupid, but if I do a factory reset then does the warranty remain? Better safe than sorry I guess
I just played 4 minuts of hill climb racing and lost 3% of my battery, this is not normal. Does anyone even have a solution for this? All I see on other threads is questions and questions, but I don't see anyone saying "That worked and my battery life is normal now"
It's normal if screen is bright. Especially if carrier bloat is still there. Post screens, all you have, and what carrier. The phone could have been sick in a search state.
I don't think my phone is tied to any carrier, it was bought from just a regular electronics shop, but frankly I did a facory reset and didn't realize that all my screenshots will be gone too. Do you really think it's normal that 10 hrs of idling causes 15% battery loss? And it has the stock LG apps (safety care, life square, cell broadcast etc.). What do you mean by "The phone could have been sick in a search state."? My screen brightness is on 70%.
It's normal with bloat in it. They all have bloat stock. 70 is high and can eat at the battery pretty good. I mean it could have software glitched and was struck searching for activation behind the scenes. Use Wake Lock Detector and see what is keeping it awake.
This, almost 20% drop was caused by downloading 3 apps (facebook, facebook messenger and twitter), updating ~10 apps (all done via wi-fi) and rearranging my home screen.
Steamer86, are you sure? My friend told me that he has been 36 hrs on one charge without changing any settings and just downloading apps, playing games and testing the phone.
Your idle is great at that point in time. Facebook is a battery killer. That's a lot of activity with 70% brightness all the time. It's 17% and medium higher side usage and an hour+ of screen time. What are you expecting? At this rate with 70% constant screen and Wi-Fi pushing pretty good you would get almost 6 hours OST. That isn't bad bud.

I hope you are right, but for helping and giving advice I'm going to hit that 'thanks' button
This night i lost 18% of my battery and my phone was almost all the time on deep sleep.
But i did notice something weird, battery usage shows that Android OS is using up most of my battery and when I press on it and then hit the back button then the Android OS changes to something called surfaceflinger for a millisecond (check the screenshots)

Can you try putting your phone in airplane mode and then turn on Wi-Fi? If you aren't using a cell carrier than there's no need to keep that on.
See how this works in increasing battery life for you.

Tab Pro 8.4 Battery Life

How much battery life are you guys getting on your Tab Pro 8.4? I bought mine couple of days back and I felt it's disappointing.

What bugged me was the disappointing battery life when the screen was turned off (not completely powered off of course). Even in airplane mode it would die in a day or two just sitting around. Battery stats showed Android System and OS were killing the battery. I never figured out if there was a setting or something to fix it.
Instead I loaded Cyanogenmod 11 on it a week ago and now it uses only 3% of the battery a day when I'm not using it. I don't miss any of the Samsung extras.

Something must be keeping it awake. My tab has excellent standby battery life.
Doesnt lose more than 5% in a day. I do have the setting to turn wifi off when in sleep mode though (unless plugged in)
Battery life on the whole varies. Video watching through the stock video player drops about 10% an hour. Surfing would depend on your browsing habits. Gaming drains close to 20% an hour. Pretty standard. That along with the excellent stand by time means I get about 2 days of use on a charge.
Every day at work telephony, internet, email, IMO 24hours, 24hours Bluethooth Gear 2 connect. Dinner consists of my tablet battery 55%. For me life is great. My tablet root and frozen Samsung Apps (Bloatware) ... XDA .... Try the Nova launcher from the Play Store to Improve speed. Set it as your default launcher then Disable / Turn Off;
Flipboard, MagazineWidget, S Voice, Samsung Apps, Samsung Apps Widget, SapaMonitor, Screen Saver, World Clock, and (Hancom, Office for Android Share, Hcell, Hshow, Hword, Updater, Viewer Launcher, and Widget) if you do not plan on using it.
We will be adding Quadrant test 24,000 points on the original ROM.
Play google baterry doctor.
Battery life is good its an app thats draining the battery.

Yes it was using as much battery as watching a movie with the screen on. Something was terribly wrong with it. I think this behavior started after a software update I got from Samsung.
I turned everything off including Wifi and it was still eating the battery while sitting there with the screen off. I have never seen that with any Android device I've ever owned.
But I'm happy with Cyanogenmod. Battery life is outstanding now.
My battery life was mediocre, and then I put cyanogenmod on, and it went to dreadful. With the tablet at 100% and OFF, untouched, it would be 20% down in 10 hours. In contrast, my iPad loses maybe 3% in that time, doing the same thing - tracking email.
I ran a wakelock tracker and noticed that Exchange Services has it awake about half the time. The total time. Like in 10 hours Exchange had it awake (with screen off) more than five hours. Effen ay. Something is seriously screwed up with how Cyanogenmod's Exchange talks to the two Exchange services I use. Switching from Push to "5 minutes" has helped significantly; Exchange is still the worst culprit, but now only by a factor of four rather than a few hundred.
Ideally what I'd like is the new Exchange apks modified to prevent admin and fixed to be less wakelock intensive.

Cyanogenmod has their own version of Exchange?
Our Exchange servers at work are ridiculously slow and unreliable. They can take two minutes to return your mail which is a major drain on your battery if it's set to check it every five minutes and you get a lot of mail. Sometimes they'll just stop responding and leave you hanging. The IT people just tell you to keep trying and you'll get your mail eventually.

Dunno.. 7-8 hrs I guess. Screen on time really doesnt mean much without any context.
I can get 12hrs+ watching videos on 20% brightness. I can kill it in 4 hrs playing games at 100%.
Like I said, the standby is excellent. Drains less than 10% in 2 days. So for me, I have about 90% to use over 2 days.. and from my experience,
video drains less than 10%/hr
gaming ~20%
reading books drains less than video.
General surfing, mails, social networking uses between 10-15% depending on how you are using it.
My brightness is usually around 40%. Goes up rarely when I'm using it bright conditions. Goes lower when I'm reading late at night
Should give you an indication of what you can expect from the battery depending on your usage..
Mine drains about 10% per hour while constantly using the device for light tasks, such as reading, web surfing, and watching some YT videos here and there. That increases to about 15%/hour when I watch movies. So after watching a 2 hour movie, I expect to see about 70-75% of battery left. Now if I'm listening to music for an hour at the gym with the screen turned off, it only drains about 3%.
At first, I thought that was pretty mediocre and felt disappointed. But I've taken my tablet with me on many trips and never had it die (usually just close to 20%). I rarely ever use my external battery pack. I know this will vary depending on how long the trip is and how much you're using it, but I'm just saying that it meets my needs despite having a lower battery life compared to some other tablets. I do all I can to extend it, but I don't have to constantly watch it.
Last night I charged the tab 100% and with Wifi off (sync for 1 min every hour. )
Today the battery is at 71% - On battery 13hours - 44 mins
27% Android OS
24% Google services
13% Android System
8% Onscreen time - 20 mins
Should I flash CM to fix this?

CM won't fix that. Install Better Battery Stats or Wakelock Detector to nail down the precise problem. If you're using them, it could be Exchange Services or Google Drive (yeah, that turkey wakelocked me to oblivion!), at which point you at least know what to attack.
You can find BB on XDA here and WakeLock Detector on XDA here, both are also in the Play Store.

Google search with 23 mins of wake time and Gmail with 6 mins.
Currently Deep sleep is 14 hr 26 mins. Total time is 17h 5m. Awake is 2h 39m. Screen on time - 27mins.
I added the google now widget a couple of weeks back and that caused some wakelocks and overnight battery drain. Removed it and didn't have the problem.
The battery life is pretty good for me. Was out a lot, so had wifi off for large parts.. watched videos (from device), read some books, played some Asphalt (not much.. around 30 mins) and some browsing/mails..
Got 11 hrs screen on over 2.5 days and still have 15% left.
Yeah was indoors so the brightness was never over a third (~30%) and reading books really doesnt drain much battery(especially if its at night and you turn the brightness further down)..
I'm not saying people will get 10+hrs screen on with their device and usage constantly.. 8hrs would be realistic.. but the point is, the battery is a lot better than I had originally expected.

I have this same problem - except my GTP is 100% stock, unrooted. I can go into Settings/Battery to see that Exchange Services is chewing my battery. It will die in less than 24 hours, even if I don't use it - as long as it has a WiFi connection. I think if I turn off WiFi, it will stop attempting to sync and the battery will last "normally". I don't know for sure, though, as I haven't tried. I'm not interested in a tablet with no network connection or even without my email.
I'm going to cut a VERY long story short (at least, here) and say that I have spent several hours logging the ActiveSync traffic between my tab and my server, poring over the logs, and I have identified the problem. It's one particular item that is failing to sync, which causes the tablet to retry the sync every 1 second. The sync failure causes the server to log an internal server exception every time - despite the ActiveSync requests from the tablet being correct. I also found a Microsoft KB article that appears to address this exact problem, and MS has a hotfix available for it.
I have talked to Tech Support at my hosted Exchange provider and they have confirmed with their operations staff that my server does not have the MS patch that is referenced in the KB article installed. Unfortunately, they are giving me a bit of the runaround on installing it. I only have one mailbox hosted with them, so I have no pull. They sound like Verizon. "We have to thoroughly test this update in our lab before we can install it on your server." And "nobody else has reported this problem and we can't put too much time into a problem that only one user is experiencing."
So, I am now just waiting for them to install it on my Exchange server and see if it really does fix the problem for me. If it does, I will be posting about it on XDA and the AC forums, as a Google search showed me that a lot of people, with a lot of different Android devices, have this same problem and nobody seems to know what's really going on or how to fix it. I will try to remember to post back in the GTP General subforum specifically, too, so stay tuned.
My battery life seems to be getting better as the battery gets some more charges on it.
Sounds basic / silly, but i simply put mine in battery saver mode and that made a big difference with little effect on performance

Got my new 6p two days ago. Seeing ridiculously bad battery.

Have updated until the update notifications stopped coming. Sitting on 6.0.1 with Feb patch. What can I do? I was wondering if this is a problem with stock rom and moving to something like pure nexus would help?
I searched Google (and Xda) and found there are people both affected and not affected by this problem. Any insights would be much appreciated.
Thanks!
Edit: if needed, my SOT right now sits at 2h35m58s with 30% battery left. Have screen listed at top on things using battery most with 8% and it shows 5hrs worth juice left.

The same happened to me - new phone, ran all the patches, and craptastic battery life. A factory reset fixed it.

Thanks for info! I am planning to swap stock rom for pure nexus today. It will include a full system wipe so here's to hoping. Will report findings in a couple of days.

No widgets. `Google now` and `google now on tap` turned off. NFC turned off (Wifi, BT on). Listening for `OK google` turned off completely. Screen brightness managed by adaptive brightness.
Apps include the normal google ones that came pre-installed and whatsapp, slack, apple music, pebble time, harvest (timesheet app for work), pocket, sync pro (reddit) and 1password.
I did find out that the device seems to be awake much more than the screen. Seems like a wakelock. I'll have to root the device later today and install wakelock detector to see what's up.
Over 2.5 hours SOT with 30% left isn't the end of the world. People eek 6 hrs out of this phone either with greenify or naptime or they turn all the location and background services off.
I'm at 17% with about 3.25 hrs SOT now on a third party ROM without greenify and everything running in the background. If I get 4hrs+, I'm fine with that. I have chargers everywhere.

Yeah I don't really care about SOTs and stuff. Only put it here because I thought it may help someone think of something that might be wrong. The actual problem is, I am literally seeing battery percentage go down as I use the phone. I browse a few pages on chrome, maybe 15-20 minutes and my battery goes down 6-7%. Neither of my previous phones did that and none of them were known for their good battery life like nexus 6p. That kinda has me concerned.
I'd advice you to charge your battery full (leave it on charger for 30mins after it says that it's full). Then use BetterBatteryStats background while you use your phone normally all the way down to 10%.
Take screenshots from BetterBatteryStats and from battery (from settings).
There are quick toggles for Wifi and Bluetooth, no need to keep them on constantly if they're not needed. Bluetooth is known to drain battery for some users (not me though). Screen brightness is 100% with adaptive brightness? Are you always in a well lit area? I use 50% w/ adaptive. I usually get something between 4.5 to 6 hours of SOT.
Pebble time can be your drainer, I remember ppl complaining about it a while ago.
So I flashed purenexus with elemental x. It probably is better to let it go for a few recharge cycles before commenting but things are already looking very good For anyone looking at this in future, I suggest a minimum of system reset (or flash a new rom if you wanna go all the way).
I'll monitor the battery life over this week.

Phone Idle under Settings/Battery

What runs under "Phone Idle" on the V20. It's been the largest battery consumer for the last week of use that I've noticed. My wife's V20 is the same and I had my brother check his and his wife's V20.
I'm only asking because I'm not see great battery life like other have been reporting. I don't have live wallpaper, have only two widgets on the home screen. GPS is set to battery save, screen is set to auto but that doesn't even come close to chewing up the battery.
Sadly I feel like I'm still using my old 2.5 year G3 where it'll need a charge mid way through the day.

Really??
Pretty sad that needs to be done on a week old phone with minimal apps. I'm not even a heavy user.
I feel like I'm back on my old DroidX days where everything was a factory reset but never helped...

I agree with you. Although my phone is just beyond a week old and does have all my apps installed, a factory reset can't be the solution here. This is the typical "I don't know how to fix this" answer always given by manufacturers and carriers.

In the roughly 3 weeks I've had my V20 I've only seen this once where phone idle was higher than Screen. I started looking thru all running apps for 'keep awake' time being high and noticed Android OS had keep awake of over 2 hours when it's normally less than an hour after a full day use. I power cycled the phone and it stopped.
The weird thing was Android OS didn't show high battery usage even though something was triggering keep awake. Looks like the keep awake was causing phone idle to be high.
I'd look at everything in your battery usage to see if you have any high keep awake times.

Sorry did not mean to be short in my response. When you set up your phone did you restore it from another phone using the nfc bump thing? I did the same and my phone battery was the same way. Wouldn't last even half a day. After i factory reset and set everything up manually i get 18+ hrs with 7 hrs screen on time sometimes.
If this situation doesn't apply to you then maybe a reset won't help. But you have to understand your situation isn't normal.
Make sure Google now features are all turned off and not running in the background.

I'll have to go through the apps one by one like I did previously on my G3 and see. Now within the battery stats there is only a handful of apps like hangout, play music, chrome and camera. The rest is OS related so that's why I was curious what ran under Phone Idle.

No and sadly I was looking for that feature a week ago but couldn't find it so I had to individually install most of my apps I had on my previous phone...made for a long night along with the additional emails and configuration or icons and such.
I'll keep digging away at the phone...I really want to like this phone ?
Has there been a definitive resolution to "phone idle" battery drain? I just got a V20 2 weeks ago on sale for $360 and its a fantastic upgrade over the One+1 I've been rockin all these years, but I'm also suffering from mediocre life due to whatever phone idle is. Some forums (for other phones) say phone idle is related to your wireless signal. I'm still with the same carrier and frequenting the same locations and had no such battery drain with that old One+.
i finally discovered whats was goin on with me..
i had the same issue..
phone idle was topping my battery usage list
it turns google plays have this "locationmanager service " and locationwhatever" that kills your battery over wifi even with location button off
Go to locations/ 3 dots in top right corner/ turn off WiFi scan. See if that helps.
My phone has been suffering from poor battery life for quite some time now, here are the screenshots, Android OS has been this high on almost all battery cycles.
I disabled wifi scanning as suggested above and will watch the performance, does the community have any other inputs to fix this? View attachment 4212978View attachment 4212979

Phone idle is always the biggest battery draw on my phone too. I have minimal apps too. No Facebook or similar types of apps. I'm on a Verizon V20 stock with the latest security update. Is this normal V20 behavior to have phone idle consume more battery than everything else?
how about doze mode , isnt that meant to help with this sort of problem ? ( my phone is currently on a ship )
Any update. İ have the same problem

So what did you do?
Would also be grateful if anyone shared a solution.
I specifically have a SIM-unlocked Sprint model (LS997) which am using in Europe with another carrier.
Using it in LTE preferred mode drains about 10-15% overnight.
Using it in WCDMA preferred mode drains up to 5% per night (yes, wifi and cellular data OFF and many apps greenified) . So I'm really interested in how this can be fixed and achieve 0% battery drain across several hours.
Or maybe it's SIM-unlocked Sprint ROM related?? I can't root my phone since it has the Feb 2017 patch and is a ZV6.
I suspect rooting it and using another ROM would solve this + the annoying issue of not being able to send images via FB Messenger and Viber while on cellular data (I imagine the Sprint guys placed some kind of restriction to deny media transfer for these apps when using cellular data).
I have noticed this too.. wondered why "phone idle" takes most battery... any suggestions would be great!
I am also curious about the solution. Phone Idle is at top. Even without SIM card. 30% drains during a night (everything is disabled, but no airplane mode is on). I tried factory reset, reinstall older ROM, replace battery, use no app but still sucks.
hi
my v20 phone battery draining was about 1% per hour before (about 7% totally ) and recently increased to 2% during sleeping time overnight. (draining 15% overnight in sleeping state)
it seems that during day either performance off battery is decreased.(about 5h with wifi and screen on usage)
Fast charging while second screen is On , is slower than when it is off therefore when second screen is Off , fast charging goes better . exactly , first 30 mins fast charging makes about 40% battery charge(instead of 50%) and after 60 min leads to 85% and full charging taking place after about 100 min instead of 80 mins.
another important thing is that sometimes shades have been seen on the LCD that many users have complained about it.
phone information is :
Android security patch level: September 1, 2017
BASEBAND : MPSS.TH.2.0.1.c3-00045-M8996FAAAANAZM-1
KERNEL : 3.18.31
BUILD NUMBER : NRD90M
SOFTWARE VERSION : V10g-AME-XX
MODEL NUMBER : LG-H990ds
my actions are as follows :
phone is factory reseted. No third party apps is installed. [especially social media apps.]
battery calibration steps for not rooted phones is taken place.(turning off the phone and charging several times repeatedly).
testing battery drain in safe mode in done and didn't change results
turn off location services and location scanning for WiFi and Bluetooth scanning
turn off WiFi being On during screen is Off.
turn off auto sync, NFC, GPS etc.
not using auto brightness.
not using comfort view .
turn off location services and location scanning for WiFi and Bluetooth scanning
second screen is off during test overnight. (either with second screen is ON with faced down to lower brightness in other day test )
phone is in Air Plane Mode and all data services is off.
system apps like Google services and Play and Assistance is limited by permissions.
following are some advanced battery drain overnight figures of my phone for more analyzing.
any help with this issue is appreciated.

Trying to track down cause of recent battery drain issue.

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.
