Every once in a while, my Nexus 7 will claim that "background data is disabled" when I open the play store to get updates. I'm certainly not changing the setting, and if I power cycle the Nexus 7 (rather than digging up the background data setting) it works fine after it reboots. I wouldn't think a reboot would normally change a setting like that, so what is going on that makes it believe background data is disabled? Is the tablet dying and this is an early symptom?
EMUI 8 has a misfeature in which it kills running services when it goes into sleep mode. This is why many apps misbehave under the stock ROM.
You can stop this from occurring by:
Settings / Battery / Launch
You want to turn off "Manage All Automatically". This might entail turning it on and then back off.
Then go into "Manage Batch Manually" and check the three checkboxes at the top of the screen labelled "All".
You can certainly enable this "feature" for some apps if you want the behavior of not having them auto-launched on bootup, not launched by other apps and/or allowing them to run in background, but this should probably be only very sparingly used as the app won't know that you want it to be killed and is likely to misbehave.
This will allow the battery to drain a bit more than it does with the aggressive app killing, so it's a trade-off.
I know of no other manufacturer that does this and I would imagine that Google would frown on what Huawei is doing.
Hope this helps.
Note: New apps added will have to repeat the process. Totally lame!
Hi all,
I seem to get this issue with pretty much every single Android Device I've owned in the last 8 years, particularly Samsung ones, and that's the good old "Android System" battery drain.
I have tried everything over the years, except rooting the device, but nothing has ever worked as a permanent fix.
I have tried:
- resetting device
- clearing cache
- restarting phone
- Shutting down background tasks
- Low battery usage location settings
- Deleting apps
- a million other things
But one way or another, Android System will eventually make its way back to the top of my battery usage stats.
I've come to the conclusion that it's the OS itself that's badly coded which causes this.
Has anyone, anyone, ever figured out a way to get on top of Android System battery drain?

I'm not sure this effects that, but while setting up phone from a factory reset etc, do you Uncheck the fields that pop up such as analytics, wifi scanning (even while off) and all the other ones ?
I uncheck all the crap i can. It's possible if you leave those checked that could be the culprit a bunch of services running in bckgrd....
Just a guess....but if you say this has happened on all your androids....maybe this is why.

Yep I un-ckeck all of those fields. Makes zero difference overall (I have tried both ways).

That sucks, could it be due to social media apps syncing constantly? Sorry I'm out of ideas....

Ibreak, maybe the problem is caused by apps sending reports and analytics via google services, samsung related stuff always sends analytics, even if you do not facebook, the damned thing is always lurking and consuming resources, google app and chrome also are resources-hoarders, I use ccswe to disable all useless firebase, crash, analytics, ad listeners, campaign trackers, components and some boot listeners within many apps

Enable Developer option
then go Settings» Developer options» running services
Here you should see a bunch of services running. A number of them should fall under Android System, close all related to Android System (it is ok to do so)
Then under Google Play services close all (well two of those services are persistent so they will auto start back in a couple seconds, lockscreeen service and Google location service), nothing you can do about this other than to disable Google play services which would then cause a lot of apps to cry like pandora, samsung internet browser, play store, YouTube etc.
Then go settings» apps» 3 dots at upper-right hand corner» show system apps» android system» battery» disable background activity
On each restart Android system background activity will be automatically enabled so just disable it on each restart.
The thing is it could be a number of apps or services that is causing the issue through Android system but a good indicator of which app might be causing your issue is to check Android system memory which is right below background activity, there it should show which app is accessing the memory through it the most. Disable that app or clean its cache/data.

It's in the same place you'd find background activity, but instead of going to battery, go to memory.
settings» apps» 3 dots at upper-right hand corner» show system apps» android system» memory
At the top above average memory usage you should see the app.
I would recommend using a package disabler (ccswe from the play store or package disabler pro from their website)
You can disable a lot of things but DO NOT disable
boot agent (could lock your phone in bootloop)
Android system (could hand your phone on boot up)
One UI (unless you have a different launcher installed and enabled)
IMS is important too
There's one more I can't remember right now, but you get the idea.
If you're not too sure if something can get disabled with no harsh side effects then just post the question
settings» apps» 3 dots at upper-right hand corner» show system apps» android system» mobile data
Shows a list of all the apps that have access to the network through Android system, disable the the ones you're sure you're not using or will use. That should shorten the list of potential battery drainer.
Thanks again.
It just shows an app called "face" under Android System memory. I assume that's for face unlock.
Be careful with disabling OneUI, because it will also disable the task manager and you'll got a really ugly one instead.

Yeah that's for face unlock. I used to use it but since the fingerprint scanner update it has been working really well with my screen protector so I don't really need it anymore so I have it disabled.
If you don't use face.
How i use my phone to maximize my battery is simple. Things I don't use or need I keep them disabled, some I simply disable until I need them like the play store or galaxy store etc. Every other day or so I would check those apps to see if there is an update I might want to install.

I only use the fingerprint sensor, but it's still shows (only) Face there. Any idea?
There's really no fix to Android System drain, it's especially worse when you're on mobile data.
Hello,
I have an issue with my Note 10+ where apps that are running in the background are being killed and they show no notifications.
For example, if I'm downloading an app from the Play Store and I went to home screen or switched to another window, it just stops installing, until you go back to the Play Store then it resumes installing the app. Also, the auto-update for apps is not working at all. I have to go to the Play Store and install the apps manually.
One more example is the Gmail app. I don't get notifications instantly when I receive an email. I get all email notifications when I unlock the phone.
I have tried everything related to cache erasing/disabling battery optimization for the Play Store (and Play Services/Download Manger) and Gmail, making sure that these apps are not in the sleeping apps list, etc. I even tried wiping the phone's cache and resetting to factory settings. Nothing works and the issue persists. I have adaptive battery enabled, and Power Mode sat to "Optimized" (PS: I tried disabling the adaptive battery and setting the Power Mode to "High Performance" with no luck.
My device is Exynos.
Anybody facing the same issues? This is really annoying and frustrating, and I'm thinking of switching the phone because of this issue.
No such issue. I don't use adaptive battery nor anything under app power management; also no auto optimisations or auto restart. And of course no app, God forbid, that clears or otherwise optimises memory.

I am facing the same issue on my Note10+ and S10+ and even with my Pixel. I think this is an Android problem and not manufacturer specific. I have also disabled any app power saving and app optimizations but whenever I manually check the Play Store there will usually be several apps waiting to be updated.
This happens with my Apple devices too. My iPhone XS Max and 11" iPad Pro never auto updates apps.
Is there a way to prevent an app from ever being killed? I have 2 examples:
1) Fitbit app (background sync service, specifically) - when this stops running, some features on my watch quit working until I launch the app and sync manually.
2) Battery monitor app - I've tried AccuBattery (my preferred app), GSam, and BBS, but they all get killed and restart, and therefore give inaccurate information. BBS doesn't die as often as the others, but I don't like it as well. All 3 have persistent notifications, so I can tell when they last restarted.
I've set Battery Optimization to "Don't Optimize" for all of these. I've tried turning off all 3 of the settings under Advanced Optimization (probably unnecessary, no noticeable difference). I've also Locked each of these from recent apps. Are there any other settings I'm missing that could prevent an app from being killed? Possibly something new to Android 11? Fitbit and AccuBattery worked fine on my previous OP7P with Android 10.

I have try to to go to developer mode and go to standby application. go inside and set the app you want to always on to active and remember still set battery to don't Optimize and locked the app. Do not click the clear all button.

Interesting, I haven't seen that before. Thanks for introducing me to something new. All of the apps in question are currently grayed out and say Exempted, so they shouldn't ever be put into standby.
Disable all power management*, Android does fine without it. Address any remaining power hogs individually on a case by case basis.
Power management will cause erratic behavior and can even increase battery usage even after its lame "adjustment" period.
To check if it is fully disabled go to Developer options>Standby apps, all buckets should show to be in their active state (and can't be manually assigned), if not power management is enabled.
Make sure allow background usage isn't disabled on the apps you want to run.
*yeah turn all those optimizing toggles OFF.
Only fast charging should be toggled on if you use it.

How does one disable all power management? I don't see any sort of global switch for that. Turning it off entirely seems drastic, but I agree that power management is generally more trouble than it's worth.
I did verify that the apps in question are allowed to run in the background and use unlimited data.

It seems like you're setting up right. Check the Stand by apps status.
When you first load Accubattery it gives an option to disable task killing in settings, Pro version.
Uninstalling then reinstalling it sometimes works for me; clearing its data does not. I was getting the same error message until I just reinstalled it
Just don't take Accubattery too seriously... it's useful up to a point.
I'm on Pie. Google really screwed up 10 and especially 11... so yeah it could something new as Google insists on changing things even if they're already nearly perfect
If that fails check with Accubattery for guidance with 11. They are responsive to emails.
They may also be punching out an update.
