High battery drain whilst idle - Nexus 6P Q&A, Help & Troubleshooting

After a few weeks of battery problems no matter what ROM (or stock) I used I wiped my device and left it running without restoring any apps. Here's the result:
https://dl.dropboxusercontent.com/u/1623843/Screenshot_20160713-170321.png
So, that's about 35% drain in 6 hours with the screen off and the phone sitting on a shelf. It seems a bit much to me - should it be that bad? If not, is it likely to be the hardware, or could there be some other cause?

Wifi and bluetooth scanning on? Backup in settings turned on? These are first things that come to mind, they tend to get bugged and cause wakelocks not allowing phone to sleep properly

Thanks. Wifi and bluetooth scanning are off (I turned them off some time ago in case they were the cause), but backups are on. I've turned the backups off and will see if that makes any difference.

Turning backups off and aircraft mode on doesn't seem to make much difference.

Install Better Battery Stats and monitor the wakelocks from there over a period of 24hrs and report back here with a screen shot from the kernel and partial.

Here are some from last time I checked it; it was running CM13 at the time, though whatever ROM I choose seems to make little difference:

Nest, Tweetcaster, Pebble and the watchface for your Pebble are high.
When I change ROM or start from fresh, I always format boot, data, system and user data and never restore my backup but only copy what I need (photos, music, apk to be installed, etc.). Its a pain in the ass but at least I'm on a fresh OS and partitions.

I've tried wiping as well, and backed up all my apks with Titanium Backup for reinstallation, although it doesn't seem to have helped. Currently I'm getting higher than expected drain without having re-installed those apps.
Initially I thought that Nest was guilty, but removing it had no effect. I removed those other apps as well and there's still a higher power drain than I used to get.

Having left the phone sitting all day with aeroplane mode on and Better Battery Stats installed, here's what I found:

Surely losing half the charge in 9.5 hours whilst in deep sleep is not expected behaviour? If it is then no wonder the phone wasn't lasting a day with that base degree of drain plus the drain from actually using it as well.

Phone won't sleep

Spare Parts tells me my phone isn't sleeping, but partial wake doesn't show any apps keeping my phone awake. I'm starting to get tired of hooking my phone up to the charger every few hours.
Sent from my HTC Evo
Is there a question you'd like to ask?
So if you look at partial wake usage, it doesn't show any applications that are responsible for the majority of partial wake? The goal is to figure out what process or application is screwing up. It might be annoying but maybe you should hard reset or reflash your current ROM then take your time reinstalling apps so you can get an idea of what may be acting up.
I have the same issue from time to time. I notice my battery draining too fast. Check the partial usage and I don't see any high percentage.
Then I look at Other, and android is at like 80% but screen on is only like 8%, so something is keeping my phone aware.
I checked system panel history, and I don't see anything keeping it awake.
I don't know of any good way to find out what is going on.
I actually caught it happening to me this morning, also it happens from time to time at night when I'm not charging it overnight.
I've heard that apps like LauncherPro hinder it from going into sleep mode however I can't necessarily confirm it's the culprit.
launcher pro does not hinder it from going into sleep mode when it is running correctly.
if you have system panel see if your cpu usage is at 100% constantly if it is it may be a run away process. i would try wiping dalvik and cache and rebooting seeing if it fixes it.
Something else you can try is hooking it up to the computer and running adb logcat on it and see if you can get anythign from that. I have seen mine occasionally when i start up have 4g on even though i normally have it off. When i turn 4g off it looks like it is off however it continues scanning behind the scenes on log cat aso i ahve to wipe cache etc and ussually fixes it.
the problem is witht he ifnormation you have given us is it could be anything.
if u have qik installed that might be it, b/c ive noticed HUGE battery gains with it uninstalled
I'm not sure what other information I need to offer here. I have had some issues with my phone refusing to sleep before, but it would go away with a simple restart. Now it doesn't matter what I do, it just refuses to sleep. I'll purchase System Panel and see if it tells me anything. Spart Parts doesn't show anything out of place on partial wake usage.
Tango was causing my phone to wake by itself and drained the battery like crazy.
If your phone is rooted, try booting into recovery and wiping the dalvik cache a couple of times. That worked for me.
Wiped dalvik cache twice and my phone still won't sleep. I don't want to reinstall my ROM and install apps one-by-one to get to the bottom of the issue. Any other suggestions?

Have you tried warm milk?
Yes. I also tried Nyquil and hydrocodone. No dice.
I purchased System Panel and I'm not exactly sure what I'm supposed to be looking for. I don't see anything that looks suspicious. Partial wake usage in Spare Parts shows UID 10094 atop the list and by a good margin with a total time of 52 minutes. Next is UID 10019 at 5 minutes and 32 seconds, and Android System at 5 minutes and 2 seconds. My phone has been unplugged for 3 hours and 22 minutes; the battery is at 64%.
ok once you have system panel you need to let it run for about 8 hours (preferably as mucha you can un pluged) then yuo can go to Menu>moniter, history and where it shows plot click it and select apps it should then show you a list of apps based on cpu usage.
I would see if any apps are abnormally high compared to the other apps) if so that may be your problem .also if system process is high yuo can click on it and it shoud llist the process individually (if it is a system process your only real options are to wipe all reflash if wiping dalvik and cache didnt work).
Lastly if you still cant find the problem i sugest hooking the pc to the computer and running adb logcat. watch it and see if anything is looping weirdly. If yuos till cant find it sorry to say i would go with the reflash rom install apps slowly till you figure it out.
It's been running since around 2 this morning. It's almost 3 now. The only thing that's above 10% is System Processes. When I touch it to look at all the processes, suspend tops the list at 16.4% over the last 8 hours, 40.4% over the last 2 hours.
My phone has recently decided to sleep ... sometimes. I haven't changed anything. I haven't removed any apps, flashed any ROMs, or wiped dalvik cache since doing it the first time. Spare Parts still shows UID 10094 is keeping my phone awake more than anything else. I would appreciate any insight into what UID 10094 is.
Noob here. How do I know if my phone is sleeping or not?
You can go to Settings > About phone > Battery and it will give you Up time and Awake time. I just use Spare Parts because it's a lot easier.
Suspend remains as the most active process on my phone. My phone has been unplugged for a little under three hours and it's down to 67% with zero use.

How to improve on battery life after Marshmallow update

If you're looking here you might be struggling with terrible battery life after the mm update. The first couple of days and few complete cycles after my update, I was getting less than 3 hours sot, in less than 12 hours, whereas lollipop treated me much better, approximately 5-6 hours sot in 24 hours. Let me clear some things from the very start: I am not attempting to create perfect battery life by sacrificing radio speed, disabling wifi when asleep etc. I'd rather have lte whenever possible and I only stop the radios at night between 11pm and 6am, using the tasker-like app included with z5.
I will continue by explaining a little bit more thorough how I did my update and in next post will give the exact steps to follow so if you're in a hurry or only here to find tips on improving battery life, head there right away. Also, if anyone has other ideas on how to improve on battery life, don't be shy and chip in.
So, since this is my first unrooted android phone ever, I had to adjust a little bit. Where previously I was using a combination of apps such as tasker, secure settings, greeenify, logcat and BBS to diagnose wakelocks and the like, I found that when I first tried to improve on lollipop battery life with these tools, actually I worseend the battery situation. For instance greenify would stop apps so they would take more cpu cycles to start again, etc. The z5, as it is, it has awesome right from the shelf standby capabilities so I feel root for those reasons only is not that sought for, after all.
Marshmallow update
I installed the nordic combined fw with clean wipe of all options present in flashtool. Afterwards I started the phone and let it restore the apps via google backup. At this step you might want to get rid of unnecessary apps (I had quite a few of them). I let all the updates happen, then I headed back to the pc and sony pcc to restore my backup (I know some people recommend starting fresh with the apps but I am the kind of lazy person, and really spoiled by titanium backup, but well, since i cannot have the latter..). I specifically chose to restore the apps data.
After restore it might take a while for the phone and whatever apps you have to sync with their respective cloud and data. I would only mention that although I kept google photos for now (with no auto sync yet) I am rather using the sony memories cloud, it seems to me faster and more standby and mediaserver friendly. So I had some problems with photos but will try it again, maybe it works better in mm.
I haven't disabled a lot of the bloatware, actually I advise you to go slowly and carefully about that since in lollipop disabling some of the preinstalled apps result in random reboots.
What I did though, after the first (horrible) battery cycle was to clear all app cache: settings/storage/internal storage/cached data
I also disabled location scanning under settings/location menu
I also performed a battery re-calibration which you should do anyways once a month or so by letting the device deplete completely (1-2% really) shutdown, charge in the wall charger up to 100%, start it plugged in charger and verify that battery percentage reads 100%, then unplug.
I didn't take a screenshot of the 3 hours sot I got a few days ago, but here are some screenshots of the much improved battery life, second day of 6+ hours. Let me tell you I didn't go easy on the battery either: few hours of listening to flac from ext sdcard in poweramp or google play over apt-x bt, couple minutes of hangouts, few sms, lots of tapatalk/reddit, a bit of camera, in other words, kept radio lte almost the whole day (while at work), all with adaptive brightness at halfway mark
steps
If coming from complete firmware reflash, you really got to let the phone 'settle' ie, sync your emails, photos and what not cloud services you sync with. When mediaserver usage decreases in battery usage you should be fine for next step
Delete all apps cache
Optional, if you have root/recovery mode you might be able to delete system cache
Optional, disable location scanning
Calibrate battery (you really gotta do this periodically)
I would add, as some sort of maintenance procedure, don't let your phone become too hot as that not only drains the battery faster but can permanently damage the battery, ie reduce its life/capacity.
There are also other ideas that I am currently trying, however as I am not sure they help or even cause problems of their own, will mention them later on when I'll have tested it more thoroughly: it's about debloating, usage access and others

Some apps might not very well compatible with MM and draining. After a clean flashed I managed to get a good battery but after installed all apps the battery is a bit worse now.
Same observations here. Not a quality update for the moment. Having some problems with fingerprint unlocking. With lollipop I didn't encounter this kind of problem.

This is how to improve battery thread so don't start the crap about what you don't like in MM.
I think trickle charge might be an issue for some. When it's been charging for some time and at 100% unplug and plug the charger back in a few times

@sajithsajan, are you retarted? Quoting whole first post? Really?
Going to give that a try, but, what was your screen brightness
I could get five hours with the brightness slider at zero.
Pretty much useless if I'm not in dark room all day.

The post says brightness halfway brightness slider (with adaptive display).
It's been a while since this post and a couple MM builds. I think that the battery calibration is still a good procedure towards experiencing better battery life, so I'd do that every month or so. Otherwise, look for more obvious issues. Just the other day I noticed a new --and very well rated-- social app I used for a few moments then, half an hour later it didn't let go of the location, even in background, exited with back button.
Did you notice a worsening in battery life on 6.0.1?

Without having timed it precisely, my ballpark numbers put it within same previous battery performance.
IMO, z5 is good enough for light to moderate usage, even some gaming although not expert on that.
It is good also for standby time (I keep on all location scanning that you might have, google now active etc), music listening ,etc.
What depletes the battery pretty fast though are any camera-related action/video recording, hangouts videochat. The camera also overheats quite rapidly so there's that.

android system eating up my battery

This problem started a few days ago randomly. I never installed a new app or changed any settings. Started out while I was on a custom ROM. I tried another ROM and same thing. Tried fully erasing everything my phone and still no luck. Fully unrooted and went back to complete stock and Android system is still eating away. When I went back to stock I started the phone as new. Did not restore any apps. This is very frustrating cause it started out of nowhere and it doesn't want to go away no matter what I do. My phone is dying halfway through my day with Android system having double the % that my screen on time has
Thankzz.

Go into settings/accounts and see if anything is having a problem syncing. You should also turn off Bluetooth and set location to battery saving if you aren't using Bluetooth devices or GPS. Which build of Android are you using? Is the high battery drain when the phone is idle? In use? Both? Presumably you wiped the system cache after going back to stock?

Accounts are all synced good. I have wifi and Bluetooth scanning off. Location is on battery saving. And I'm on latest vendor 7.1.1 and usually it's when I'm using the phone. Idle drains some too but not that much of a difference.

Did you wipe the system cache? The only obvious thing that might drain your phone when in use is having the screen brightness set very high, but that shouldn't make a huge difference. You said the problem began when you were on a custom ROM but now you are fully stock? That's odd. Poor network connection can also cause high battery drain. I think if you reset your network settings it will force your phone to look for the closest available cell tower. Do you have GSM or CDMA service?

When battery is run down, what is displayed under battery>>android system>>use details? Please paste those details here. Are you in an area of extremely poor LTE signal? Have you ever used Better Battery Stats? Install it and run it for a full battery cycle. Your problem will likely be solved by a factory reset from the stock recovery.

Wouldn't high screen brightness go under the screen category and not Android system? I will reset my network settings and see if it makes a difference. I would assume flashing back to stop and erasing all data on the phone would do that and wipe all system cache as well.

I have BBS installed but without root I don't think it's much help? I will post screenshots when my battery goes down to about 15%
Some people have reported that the following works, although I don't understand why it would. Go into settings/battery/battery optimization/all apps/reset app preferences.
A factory reset shouldn't be necessary if you did a completely clean stock install but it also couldn't hurt.

I never use root even with custom Roms. I feel like I have no need for it. I did what was mentioned earlier and reset my network settings and also I disabled chrome and started using a different browser and so far Android system is the same percentage as screen. Not good but way better than before. BSS is also showing 2 hours "awake (screen off)" which is kinda alarming

You didn't see anything odd when you went into accounts and looked at syncing? For Google you clicked on the account and looked at each individual thing that gets synced under Google? If you were rooted you could try the Naptime app. I hated it but it has many fans. Basically it puts your phone in an extreme Doze state when you aren't using it, which might fix your problem. But if you want anything to work with the screen off you have to exempt it from Doze. Screen off in Naptime kills pretty much everything.
Same here. Everything stock. Just checked accounts settings and everything is good.
right now my top 5 is:
Screen 13% (2h:52min SOT)
Android System 10%
Android OS 9%
Facebook 8%
WhatsApp 5%
and in overall I've been around 40 min on Facebook, and you know that this **** consumes a lot, so go figure out how the hell is Android System and OS above it.

They are components shared by applications so that's rather normal to have them high.
I don't care about Android architecture much so only look at my SOT (which is nominal).
Those interested in why system and OS are high, should read the battery stats source code to see what's grouped under these and how it's being calculated.
I locked my bootloader last night and did a factory reset from settings. Right now Android system is at 5% and screen at 4%
I'm about to completely just give up

Android System tally is the sum total of a number of components. That it is "high" is not necessarily a big deal. The real question is: what are each of those components using? When your battery is run down, what is displayed under battery>>android system>>use details? Those usage details may help you find a problem if you even have one. Short of rooting and running a dedicated battery usage/wakelock app, these details may be the best you will get.
Decided to run purenexus and exkernel with root to get better stats. Battery is a little better but still not even close to how it used to be. Here are screenshots of everything . Woke up with 100% around 5:30 am. Went to work and the gym and wat he'd some YouTube.
The only way I found to fix this issue was to implement aggressive doze as soon as screen is off.
If you're on MM this can be done using apps like ForceDoze
And on Nougat using NapTime
Furthermore , I also implemented ElementalX kernel with Hawktail governor.
Since these changes my Screen is on top of the list in battery and maximizes my screen on time. Nothing else works for me.
The phone tends to stay awake needlessly without all these tweaks.

I really don't see anything wrong here, except awake time and maybe SOT. 4 hours SOT is very good for stock and you are at what 3.3 hours? I use the Hawk Tail governor profile in EX as well and it gives me just a small amount of improvement over stock settings. I use the stock rom, rooted with EX and get 4-5 hours SOT.

I think the 2 hours awake screen off is normal unless you use an App like Naptime to put your phone in Doze as soon as the screen is off. If you are really concerned with idle battery life you might want to try Naptime, but you may need to play with the settings so the phone works like you want, Naptime by default turns off everything that isn't excluded from Doze when the screen goes off. That includes music players and the fingerprint sensor.

Standby drain 8.1 OPM1

I seem to be losing between 8-10% overnight since clean flashing OPM1. Anyone else seeing this? I can't peg it on a particular app and accubattery reports anywhere from 0.8-1.2% loss with screen off. If I just tap the power button to see accubattery stats, the current drain without going into anything ranges from 54mah to sometimes as high as 150mah. I may try a factory reset to resolve but curious to what others numbers are.
I'm using latest stock 8.1 and find it has the best standby I've ever seen. Either your battery is over year or two and starting to degrade. Or you need to do some spring cleaning when was the last time you backed everything up and wiped internal. You'd be amazed the wonders that does with rogue apps and missfunctioning features after completing wiping and installing fresh copy of stock.

Just bought a new OEM battery that is reporting 101% capacity so that's not it. Also, clean flashed 8.1 when I loaded it although I restored from my cloud backup. I just factory reset today but honestly, I felt it was worse so I completely blew everything out again, redownloaded 8.1 and flashed again. This time I chose to set up as a new device without using the cloud backup. The only thing I manually backed up and restored was text using a 3rd party app. I am adding my apps back a few at a time but it seems to be a little better as of now but will have to give it a couple days to settle down. Not rooted yet either.
Some are reporting that "mobile data always active" is enabled by default in developer options on 8.1. Have you tried disabling this?
To compare this with op, I got 84% battery health and a drain over night of 4%. Stock 8.1, Nova launcher beta, SuperSU beta, mobile data always active is off. May an app is responsible for your 10% draining ? Any social stuff like fb ???
I turned off mobile data always active and when I clean flashed the second time, I did not put any social media apps on the phone but saw no difference. I ended up putting fb, messenger lite and Instagram back on and they aren't impacting negatively. It's only been 2 days and have only rebooted a couple times.. battery is still reporting 101% capacity. I'll give it a another day or 2 to settle down bc at some points it seems to be very efficient while others it doesn't but that's better than before the 2nd clean flash.
Looking at my accubattery stats, I'm still losing about 1.1% battery per hour with the screen off. I also noticed that so far in the ~7 hours my phone has been off the charger today, it's only been in deep sleep about 51% of the time that the screen has been off. What happened to the built in wakelock detector that was highlighted in https://www.phonearena.com/news/Android-8.1-Oreo-wakelocks-battery-draining-apps_id99715? Does anyone see this actually working or is this yet another "Pixel exclusive". I cannot figure this out so I guess I'll have to download a 3rd party wakelock detector but the reality is, even if I do find the culprit, it's usually not anything that is easily identifiable or fixable. Am I really the only one having this issue??

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.
