I get tired of talking about this issue after updating my S7 to android Nougat.
My screen-off draining too much battery. I've deleted cache partition and reset app preferences but i don't see any changes.
I've checked with GSam and it shows that Comibined App CPU used battery a lot (about 80%).
I wonder if you could help me on this issue

Hi mate
That information is not enough to solve the problem you need an app like BBS to find out who is the culprit....let it run for a few hours and check the logs....from there we can take action
i am also having the same problem. combined app cpu 80-90% also my download manager and mtp host, media manager are draining battery. when i disabled those, it helps but the i cant access Google play or anything on sd card.

My screen battery percentage is around 70%. I am wondering if that is normal because on a screenshot I saw in another thread, the person's screen % was in the 40s. If it isn't normal, can someone help me with bring the the battery usage of the screen down? (My battery is being drained and I was wondering if it was the issue with the screen .) And sorry if I seem very noobie >_<.
The higher your screen percentage the better it is because it tells nothing else is draining your battery significantly. At 40%, there are other things that are running your battery dry aside from screen.
You could post a screen shot for others to see and advice.

Ohhh, I didn't know that. Thank you for telling me! However, now I wonder what is causing my battery to drain... especially when I am web browsing. Here is a screenshot of the battery usage on my system.

If you're rooted you can always clear battery stats in CWM. Some devices appear to perform better. Also check what's running in the background (processes). Disabling things like GPS can save battery. If you use TiBu, freezing unneeded apps can free up power and resources. If you venture into that, I would suggest doing one at a time to avoid freezing apps that your tab needs running. Google/search forum as I'm sure others have posted their experiences.
Just a few random thoughts....

I notice android media process consume your android battery. I am also wondering about android media and server process in my GT- 6800 with paranoid 2.55. Here are the process that help me out
try to delete all you music or picture files and back it up to you pc
unistall the game and try to install game one by one to see which game will consume your android media process
using terminal emulator to disable android process media. I refer to this site; http://code.google.com/p/android/issues/detail?id=37199
1) have Android SDK installed on your laptop
2) enable debugging on your *rooted* device
3) connect it to you laptop via USB
4) adb shell
5) su
6) pm disable com.android.providers.media/com.android.providers.media.MediaScannerReceiver
It works for me and now I have no media process in system and media server consume reasonable memory. Thanks

My tablet is rooted, but I don't know how to clear battery stats. However, I am currently using Battery Monitor Widget Pro and I see the calibration tab. Once again, I have no idea how to use the calibration thing on this app. And I disable GPS all the time, unless I really need to use it, which is hardly ever. As for TiBu, I don't know what that is. Is that Titanium Backup?

If you have CWM installed then there is an option (from the menu) to clear your battery stats. If you don't have CWM then please download from the "development" section.

Poke around in CWM. I believe it's under Advanced. And yes, TiBu is Titanium Backup.
"Android System" keeping phone awake 24/7, draining battery life- T-Mobile Z3
I startes noticing that even after quite a few charge cycles, I'm still getting 4-5 hours of SoT over less than 24 hours. The phone is awake 24/7, and Android System seems to be the cause, but no idea why. Does anybody have any suggestions? I've attached some screenshots.
Factory reset?
Sent from my Z3
Maybe you have some apps causing wakelocks, showing through Android system? My dad had massive data usage from Youtube which confused me until I uninstalled an app that used YouTube.
Yes something that you have installed is causing the Android System to run for extended periods.
I would first try, disabling some apps in the settings menu, to see if that helps. (like throw, bluetooth, NFC, wifi, hotspot) see if any of those help
I would factory reset, and be very careful about what you install back onto the phone initially.
Or instead of reset try, clearing out all apps and re-install one by one untill you hit a bad one. If that does not work I guess reset.

In Settings>Power Management, there is a selection called "App power consumption". Have you checked there? There could be an app listed that drains the battery.
I had checked app power consumption, and unfortunately it didn't give me any further information. Better Battery Stats is also almost completely useless without root, but I did try it and saw Performance Manager or something to that effect was what was keeping it awake (in Kernel Wakelocks). I ended up doing a factory reset, and it seems like it's working fine now with the same combination of apps.
I think I disabled something I shouldn't have using pm block (package), since after some searching it seems like the phone might have been constantly searching for a blocked package, keeping it awake. It's working fine now, thanks everyone for your suggestions!
I have a Samsung Galaxy S7 and the battery was doing fine. A few weeks ago the phone started getting quite slow and the battery life went way down. I had installed a few apps around then, so I removed them and still battery life was bad. I tried restarting the phone and that didn't help. At the time I was running Marshmellow and I was using OSMonitor to watch the system. I was finding that Android OS was taking most of my battery and 30% of the CPU all of the time. Not long after that Nougat became available and I upgraded thinking that might help. It didn't help and OSMonitor no longer worked. I switched to GSam Battery Monitor and used adb to give it the permissions to see all app information. I'm still finding that the Kernel is taking 28% of my battery and Android System is taking 37% of my battery and I can't figure out why. I would rather not need to do a full reset and install all of my apps and settings again, so I'm asking if anyone out there has ideas on things to try and fix this. This is a non-rooted phone running the stock image from Samsung/Verizon.
Thanks for any help.
try activate the Battery Saving option and use it for a day and see if helps
I've had this happen to me before. The phone was getting seriously hot while it was happening too. I decided to do all I can without doing a factory reset (I was on vacation at the time, so no access to something to backup my data).
I cleared the cache of all apps. Then I disabled all of the stock apps I didn't need (like Gear VR). I also shuttered apps running in the background to about a max of 3 apps open at any given time. That stopped the insane heat issue, but Android System was still sucking 30% of the battery. I turned off Always On Display, that got me down to about 25%. A factory reset got the phone down to around 10%, and I never saw the issue again.
Before you do that I would recommend checking out this thread below as there does appear to be a bunch of other possible solutions provided by others.

But then my background syncing is turned off too...
I didn't need this before, so wondering why I should need it now.
I had same issues and was able to fix it. See the following thread for details.

Try this , it helped me a lot .
Download from the XDA forums the Kernel named : "Apollo Kernel" v7
Just flash it , and when you install it , if you dont use your phone for high end games or hard work,that requires high end specs , then you can underclock the cpu/gpu .
It s a battery life saver, plus , your components will be much better in terms of thermals/life
Let me start off by saying I was so happy with this phone and its battery life but the past couple of days I've seen it drain more than usual. Upon checking I see that Google account manager is responsible for this.
Anyone have an idea what caused this? and how to fix it?
i noticed the same on my chinese mate 9 however the % is below 40 still, from what I can see on my case is the google photos app causing all the noise I had disable synching over cellular data but haven't seen any improvement so far. I did that 2 days ago
Same here on my P10.
How many Google Accounts do you guys have linked? I currently have 4.

Thx for your replies guys!
Meanwhile I accidentally found out that this might be the process what is on other phones the Google Play Services.
I tapped on the Google Account Manager entry and scrolled down to the bottom of the next view and there it is..
Still I haven't seen the "Googl Account Manager" process ever before I assume that Huawei handles or at least displays the processes differently than others (at least Samsung) do.
For me it's a good thing since I see way more processes sucking battery than my SGS7 showed me.
Remembering the battery drain on my SGS7 the Google Play Services had pretty similar battery drain like the "mother process" Google Account Manager has on my P10.
So I think that's it
What do you guys think?
I have the same problem, lot's of times it's a Google calendar fail sync or Google fit fail sync because the system close it and when Google account has do a sync that's impossible because the apps are closed so I'm testing to not force closing Google apps. I will tell you my results

its normal for android OS or android system to use battery
android OS is in respect to the kernel however.

Still shouldn't use that much. Literally it's the most used one. One hour of screen use today and I'm down 25%
My Huawei watch is the only thing connected. No autosync no nothing. Used it minimally. My note 5 after last update and a reset lost maybe 6% all day. Android OS n kernel aren't an option. It's not on 7.0 tho
Does anyone have a solution for this? It is horrible since a few weeks (no update in the meantime, no other apps installed): Google Play Services (Google Account Manager) are very active, device gets hot, reboot helps for a short time, but almost every day I have a huge battery drain. Before the last weeks, this was not a problem at all, battery usage was super.

Do you have developer options enabled?
I've had the same problem, after diasabling developer options it seems to be somewhat better but not really cured.
I also enabled in settings the automatic memory and data cleanup as I've found that cleaning all app caches helped for a short period of time.
I fixed my by doing factory reset. Now everything is back to normal.
Also before I had a problem that whatsapp didn't show messages if I didn't open up the app. This issue also got fixed the same time.
I'm suddenly having high consumption by media server - have no idea what it means and the phone is quite hot.

mediaserver can be due to listening or streaming music, or indexing music.
its fairly normal, however if your rooted you can disable it in an init.d script.
stop mediaserver works.
or
su -c pm disable mediaserver

Thanks, I've been listening to music all day. I'm not rooted so I guess I'll have to keep on with it.
Shut down for a while then restarted the phone and it's no more getting hot.

ive still got issues with android os using the most power. i only get 6-7 hours max screen time. i use my huawei watch via BT. latest update for the USA 183
Seems to be getting worse. Now I'm slated max 27 hours. WTF
in reality battery life never gets better. The constant discharge, and charge rates only put wear and tear on the battery. It would great to have the ability to swap batteries on the fly.

I have a stock tmobile s7. It's running the latest OTA no root. Using cpuz, I identified that my CPU has been running at 90-100 percent non stop. It's making my phone warm all the time, killing my 7300 mha zerolemon battery in less then 2 hours because of how much energy it's using. I don't have the issue in safe mode. I know the phone gets super cold when running in safe mode. I haven't been able to find what process is causing this issue. Most cpu task managers no longer currently work in Nougat according to what i've seen due to a bug that prevents apps from seeing other app's usage. If I don't have another option. I'll just factory reset tomorrow and start from scratch completely. I started removing a ton of apps but still no luck. I've attached a screenshot of cpuz.
There's a "Show CPU usage" option under the monitoring section of the developer options.

That option is also broken by the 7.0 bug. It only shows the system process which is low cpu usage but won't show all running apps. (https://code.google.com/p/android/issues/detail?id=213571) According to google, they have already fixed the bug internally and it's pending a public release. That feature would have definitely helped me pin point the cpu heavy process.

Search xda for better battery stats, without root you need to give it a permission via adb
