[Q] Android System using 72%...

Hi... I've had a LOT of battery issues after installing CM 7.0 RC3 or whatever that last one was. As the Nightly builds got higher - battery got worse. I have the latest radio for this Phone, and I've even replaced it. Battery life is horrible lately. I have two batteries (thought it was my battery) - I've cycled both of them a few times, and it still acts odd. I've wiped / reloaded, same thing. When I changed the radio from Euro to US, it seemed to be a bit better. But I'll be walking around my office with 99% battery, go out, smoke, talk to two people (20-30m) and it'll drop to 88% like it's nothing.
After changing the radio to US, the Cell Standby lowered, but Android System has crept up. I have TweetDeck set for 15m refresh, Google+ is set to push sync or w/e, I have two email accounts and I've disabled the FB/Twitter apps. I'm not overclocked at all either.
Anyone have any insight on this? I'm currently on Build 153. It seems like when I play Music it dies insanely fast. I used to get 12-24 hours on this, even playing music.
Screen shot coming.
Screenshot:
And I haven't done anything today. Sent a few texts, few G+ posts, and talked on the phone for like an hour... And I charged today from 0% to full (6 hours) when I was sleeping. No music, no games.

I have noticed weird activity from "android system" lately too. I run the latest build of MIUI... but I don't notice any crazy battery drain. I'm only down to 90% with it being unplugged for 5 hours, texting a bit, figured out a route with google maps, and some minor XDA browsing.

I agree. The latest miui build is great on battery life even with the optimized ui.
I text from morning until night, every 5 minutes or so a reply is sent. Also wifi is on and using the xda app every now and then.
I woke up at 9 EST and it is now 12 EST. I haven't reached 50% yet.
I have brightness turned all the way down, screen timeout to minimum, and kill apps once they are closed.
It's all about the rom and how you use it really.

You may want to install something like watchdog and have it monitor phone processes. I had something like this happen on stock froyo and it turned out to be the media scan process.
I cleared out my media dirs on the sdcard, and things went back to normal.

+1 on watchdog. I love that app. Its not a blatant task killer, it just gives you good information on your processes and alerts when one regularly comes above your set threshold.

guys, people have reported that updating google maps drains battery. try uninstall the updates, or temporarily remove google maps, then report another day of battery. even if gmaps isnt even showing there, its said to drain battery recently.

Battery drain all of a sudden. It's killing me!

Recently my phone has been dying really fast. I checked battery stats and Android system is what's killing it. I've tried everything to make it stop and nothing works. Does anyone else have this problem? Any idea on how to stop this? PLEASE HELP.

Boot into recovery then do clear cache partition. Should clear out whatever is causing this issue unless that app is still in there

Clearing cache could and probably will get rid of it. But I bought an app called Better Battery Stats, (id link it but im new) which tells you exactly what is waking up your phone while its off. Chances are you have a rouge app, that is just destroying your battery, as opposed to a system-wide problem. That app will tell you what it is.

Ignore the battery charging cycle. I'm just showing you what I have to go through also and somewhat fixed the problem.
I have and still have %50 android os usage. Before I did this mod, the android os was the highest usage and showed awake time as well. It was killing my battery from a full charge it drained down to zero in 12 hours with 1hr screen time and the phone never being in a deep sleep. It was aggravating because I wiped my phone so many times, tried different roms, took sim card out, no wifi, wiped cache, and wiped phone with nothing installed. Still the high android still persist and no deep sleep. I'm thinking it has to be Verizon doing something or Google that is waking up the phone.
Some how I fixed it or maybe the OTA fixed it. I odin mj7 and updated to the newest version and flashed beans. From the screen shot it shows my android os still high... but with no awake time. So my phone is actually in deep sleep mode now. It's weird but I semi - fixed it. I'm still clueless on why it's so high when previously screen time usually trumps as the number one usage spot. I still have no answer to this reason but I hope it helps a bit to fix this issue.

HEY same exact thing here. Android OS usage going nuts here. I personally think its related to certain wifi / router setups.
When im on 3g/4g all day, it doesnt happen. On the days that I am stuck at home on wifi, the android OS usage starts again.
Ive already Odin'd back to MI7, took ota to MJE, rerooted, installed beans b5 and its still happening.
I think its a bug with samsung / verizon wifi. Many times I will wake up my screen and see my GPS / Wifi being used for no apparent reason even with all location services turned off. I also notice my wifi indicators being on when i turn my screen on. Then after i turn my screen on and sit at my home screen for a few seconds. It all magically stops.
Mind you, this is with no apps installed other than what is in beans stock and nova launcher.
You guys should monitor while off wifi and see what happens. It was the first thing that struck me when i was on a road trip for 12 hours. My battery life was exceptional. If it is the wifi causing problems, i wonder what it is specifically.

Simply clearing the cache fixes this for me every time. I usually do it once every few weeks.
Settings..storage..tap on cached data and hit clear.

[Q] I9505 4.4.2 android system battery usage

Hi,
Ever since I upgraded my I9505 to 4.4.2 I've noticed that one of my key battery consumers was Android System (not so on 4.3 or 4.2.2, or whatever I was running before). Right now I'm on the latest DBT ROM, but still the same issue. I've been reading numerous threads on this, tried lots of things even formatting my SD card from within the phone, but still same story. I have Google location services disabled (major issue before), Google Now hot word detection is off, S Voice voice activation is off - nada. I am running stock so getting a wakelock report is a no go. I get decent time on the phone (up to 18 hours per charge), but still want to figure out why Android System is using so much battery (it seems to be CPU time related anyway - phone is properly entering deep sleep when it should). Below is a screenshot of what my battery graph looks like about 2 hours after unplugging the phone from the charger with normal usage. Thanks for ideas!

Any ideas? In the meantime I've done a factory reset, disabled Samsung's bundled apps (e.g. S Voice), tried disabling location services altogether - still same story nothing seems to help. In OS monitor I see a constant Android system activity between 1-9%. Average is around 2-3% but it never stops.... Sadly with the KitKat permissions being what they are I can't get more details.
Here's a graph from today 3 hours after a full charge with minimal phone usage:
Clearly something is going wrong here...

Hi ,
With this information is hard to tell what is going on , you need an app like Better Battery Stats
http://forum.xda-developers.com/showthread.php?t=1179809
Let it run for 3 to 4 hours at least and then see who is running wild
Review you settings , location , mail , FB......

Thanks. As I am running non-rooted 4.4.2 I can only see kernel wakelocks which look normal to me:

33 min is not enough time to see what is going on let it run for 3 or 4 hours ...

Upgraded to I9505XXUGNK4 (DBT) today and it looks like it helps!

For posterity's sake - the firmware didn't fix the problem. My Android System, and to some extent Android OS, usage was still pretty bad. After hours of trying various things I've got it though - in my case I had to disable Samsung's Unified Daemon (EUR) and now once more my top consumers are Screen and phone idle! Hope this helps folks.

When phone is in Doze mode should i be seeing any wakelocks in the battery graph?

Hello i have posted this over on Reddit but thought that i may get more info on the problem on this site.
Sorry for the long post.
I am trying to find out what is causing my battery to drain 10-15% over night.
i have tried a factory reset 3 times and nothing has fixed it but 3 hours ago i done one again for the 4th time and so far it is still at 100% and i haven't hardly touched the phone so i am not sure if the reset has finally worked ( this time i did uninstall whatsapp too)
My question is, in this 3 hours of hardly touching the phone it is still at 100% but it is still showing being awake quite a few times in the battery graph and i was wondering if that means it hasn't entered doze because it still shows wakelocks? i hope this makes sense

People on reddit think it may be a wifi wakelock issue and have told me to try it on 4g to see if i still get any wakelocks which i will try for the next few hours.
Also after doing a factory reset does the phone need a few days or cycles to get the battery to working properly?
I should also note that for the past 3 or so days i have been trying different tests in the night when i am sleeping to see if it is an app causing the battery problem. I only have 3 3rd party apps on my phone which are reddit relay, whatsapp and tapatalk.
1. The first night when i noticed the drain and all 3 were on the phone it dropped about 10-15%.
2. The second night i only had the apps that came with the phone (they all updated first but no apps were opened like chrome so i dont know if they were set up and i was signed in) and it dropped 2%
3. the third night i removed tapatalk and kept relay and whatsapp and it dropped 10%
4. Today 3 hours ago i have removed whatsapp and the battery stayed at 100% for just over 3 hours until i picked it up and started using reddit and chrome so it seemed to not drain as fast but i still have all those wake locks.
Do you guys think it is the wifi wakelock problem or maybe an app? if it is the wifi problem will a new phone fix it as reboots and restarts with this phone doesn't seem to or if i get a new phone will it happen to that one and its actually a problem with my wifi?
Again sorry for the very long post, i am just looking to see if i can get to the bottom of this before my 15 days are up to get a refund from google.

Sorry to hear about the battery issues. Lots of complaints since the update from 6 to 6.01.
I think you have until January 22nd to return the phone, if you purchased it recently from the Google store.

Not sure if you are rooted or not, but if you are then I highly suggest downloading the Wakelock Detector app. If you are not rooted then I suggest rooting because it is the fastest way to get down to the root cause of the problem (pun intended). It will show you each process/app that wakes the phone from most to least.
Without downloading that you will just be playing a guessing game of uninstalling 1 app at a time, which could take forever. So save yourself the trouble and download Wakelock Detector. I think it is pretty safe to say most of the wake locks are from apps, so please do not return the phone because of that. I do not think a hardware issue could affect software wakelocks, and if it was a stock software bug, most or all people would be experiencing it. Good luck, feel free to report back to let us know what you found with it if you do root and download it.

Huge battery consumption, help needed

Hi all,
I am very satisfied with my device except for the battery life. I always had like 3-4 hours SOT. I was not happy but it was OK.
Lately I started charging the device every day after work (I would come home with dead phone after only 8-9 hours of it being unplugged).
So I thought the battery is defective, I must change it... and I did change it yesterday. The thing is that even the new battery behaves almost the same. It approved somewhat and now I will return home with 10% battery instead of dead phone 1 hour ago. But still the battery is terrible...
Can anyone help me, share some advice on how to improve it? I have disabled many software (even facebook), disabled location... did everything I could think of.
I am thinking some app is drawing the juice but cannot put my finger on any of them.
Some screenshots are attached that might help with your tips/advices.
Thanks!

Are you rooted? On nougat? If so get background restrictor APK here on XDA and kill background apps and tasks so they can't run if you do not open them. Lower screen brightness. Install kernel auditor and shut off cores 4 and 8.

uninstall chrome. Then try accubattery (better bcause after android 7, they join all in android system to mask each app consumption. If after this you still can't find out where's the problem, start the phone in "safe mode". Even the consumption is better in this mode you must do a full wipe in recovery mode (vol up+power+home) and after this, reinstall one app each time and see after reinstall the second one and so on until you find out in which app is draining the battery
If you want you can starting by disabling background data in settings but I think isn't the clearer way to find out

This is going to surprise you.
I've had this phone for years and I've tried everything - and the BEST result is when you DON'T DO ANYTHING except disable Facebook and Instagram, and any Google Apps you don't use.
Do not tamper with anything else.
I figure that Samsung tunes this phone so tightly that if you leave it alone it operates as it should.
Anytime I disabled anything else, battery life suddenly and drastically reduced.
The phones runtime software kicks in and if you have disabled something it checks routinely, it will keep the phone awake constantly looking for a ping back from that process.
I just went through the whole process again meticulously, App by App.
Also DO NOT enhanced messaging OR the device antivirus. If you have, you must reset and then train yourself not to engage these too regardless of how hard The phone tries to persuade you!
Then - the battery life becomes like a normal phone which means you'll still need to charge everyday but it will take you through a full heavy day... And this is fantastic!
Honestly try it and you'll see what I mean. The S6 edge plus is so finely tuned, anything you block will start a feedback loop.

I had similiar problems , the way i fixed it, i disabled/uninstalled all samsung applications what i dont use, i disabled/uninstalled all google applications what i dont use. Cold weather (like -20C) will affect the battery life too.
Disable / uninstall apps you dont need. That helped me a lot and got even more battery life while at stock nougat rom with all updates installed.
try wiping cache from recovery and reboot your phone.
I hope this helps you
