when I go to my taskmanager...(right above in the corner)
My lowest usage is 39 %.
Is this normal? or is this high?
I installed dotfred's taskmanager to see what is running @ the background...
the only thing I see when I go to the tab cpu usage is: idle process 85 %
what is this?
And offcourse my taskmanager 15 % but that's something I do understand..
That figure next to the CPU pic in HTC's Quick Menu is the amount of memory being used. 39% is very good! You still have 61% left to abuse.
Your system is ALWAYS doing something -- even when it's doing NOTHING.
Consider the "NOTHING" process as the "Idle Process".
That "Idle Process" means your system is waiting to be used or to be issued commands. Do something on your unit and the Idle Process will go down and give up cycles to something else that needs it.
In theory, if your Idle Process is 100%, it means that nothing is being done on your PPC and that it's raring to go (a good thing).
If your idle process is low, it means that your PPC is busy handing out CPU cycles to the various applications demanding them (in your case, the task manager itself).
I hope this helps!

"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?

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
Hi everyone,
I know battery issues have been discussed a lot, but I see others with on screen times that are far above what I am able to achieve. When I first started using the S7, the battery life was fantastic but I feel that every update has gradually worsened the battery life.
Are there any suggestions to see what is using so much battery? I've attached screenshots that show 23% remaining after less than 2 hours screen on time. I've tried a few battery monitoring apps but they do not provide much more info on "Android System" and "Android OS"...
Thank you!
Wanted to post a new screenshot... battery at 23% at just under 1.5 hours of screen on time (with auto brightness)...
Could try something like GSam battery monitor if you haven't already, seems to be a popular one
https://play.google.com/store/apps/details?id=com.gsamlabs.bbm
Have you cleared the cache from recovery yet?
Obviously last resort would be a factory reset
And if you have upgraded from MM to Nougat and have not factory reset since, that's likely the cause, always advised to reset after a major OS upgrade to prevent things like this happening

Thanks, I will try that battery monitor but I think it will continue to just list "Android System" and "Android OS" rather than the detailed process that is draining so much battery...
I've tried a factory reset after upgrading to Nougat - no difference.
Android System shows only 11% usage on your screens with only 335mAh which is also 11%, so that's not the issue
Screen and Android OS are both using less than 10% each, so at most between those three that's under 30% total battery usage

Good day.
In GSAM you have an option (Enable more stats) in 'more' menu, that gives you the apps that are battery consuming. Try that.
Hi.
I've got a similar experiance on a new S7 bought last week.
It came with Android 7.0 intalled right out of the box, so this should have been a clean install.
My top battery drains are:
Screen: 20% (5h screen on time)
Android OS: 12%
Device standby: 11%
google play services: 10%
android system: 8%
mobile standby: 8%
camera: 7%
I deinstalled several apps, and disabled a lot of automatic syncing and other things like google cast or nearby. The "ususal things" for a better battery life...
I've used a lot of camera, messaging, internet browsing, but none of these apps are on top... it's the "Android OS"...
This is strange, because I never saw this kind of beahaviour on other smartphones.
There's one Samsung app I cannot deactivate: Knox. And it's showing the same percentage of 8% like "Android System" (perhaps because it's a subset of the "system")
I don't want to use Knox, like many other private customers would.
Is there a chance to stop it?
I'm having the same problem. Today was my new low record, 10% battery left with 1h45m SOT.
Wlan has been off, BT off, 4G data on, most used app was Spotify which I used with headphones for about two hours. Before Nougat update I could get 4-5 hrs SOT.
I don't use Facebook or FB Messenger apps, and have actually disabled FB and a lot of other junk with Package Disabler Pro. Using PDP doesn't really have much effect on my battery life.
Is it safe to clear the cache if I'm not planning to do (yet another) factory reset?

System apps aren't measured individually for performance reasons, so you're right, it's a subset of "System" and not necessarily using that amount of battery. Knox is a security feature. You cannot disable it without modifying the firmware and voiding the warranty. It genuinely doesn't do much if you don't use it though (but might get annoying if you're rooted).
Hello everyone, I'm in trouble.
22 Ultra is simply eating battery at indescribable levels. Yesterday we went on a trip from work, I left my home with 100%. During the day I did not touch the phone, a bit of a camera but beyond that really nothing. My battery was about 40% after about 3 hours, with no screen use at all! On the other hand, a friend at work with Xiaomi came out with 100% and after 3 hours was on 85, and he did touch the phone here and there.
I don't know how that makes sense, and it's no longer clear to me what to do to solve the problem. I debloat, deleted and disabled a number of irrelevant apps but still, the battery is being eaten. How can I solve it? Please help me!
Draining battery so fast, 20% per hour while idle is not normal, so you definitely have a problem.
It looks that there are two possibilities here:
- Battery malfunction
- Some active process in the background that is using lots of processor power constantly.
If battery is damaged / not working properly, the only solution is to replace it. Still, this doesn't look like a case of duying battery.
If you have some persistent process running in the background that you can't get rid of by debloating, it can't be stopped by restarting the phone, and its not visible in the battery usage section, i would say that factory reset is the most effective option here, since you stated that you tried to deal with it in a various ways already.
You could also wait a bit until you get chance to update to OneUI 5 / Android 13, which should solve your problem, if it's software related.
Hope that you will find solution soon

I want to keep the factory reset as the last option....
Every single app that I don't need at the background I disabled from running in background.

Try to wipe your system cache.....it won't do a factory reset but might solve the issue while keeping your phone as it is.
Volume UP button along with the power button until you see Android screen
Scroll down with volume down until you reach wipe system cache and reboot
sometimes, it won't show up while you press the buttons....in that case, connect your phone to your PC/Laptop with any USB C cable and then do it.
Second solution, you can try Samsungs App Booster.....get an apk from the net. It generally helps as well.
