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.

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:

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.
The HandleMediaEvent sub service of Android System is randomly causing solid bar wakelocks for me. Rebooting the device usually fixes the issue temporarily. The only thing I could find after some googling on the issue was this older thread on a GS4 http://forum.xda-developers.com/showthread.php?t=2483630
it seemed to think the issue could be caused by bluetooth devices. I Have a Moto 360, and use bluetooth earbuds almost everyday. But, I'd think there would be more reports of this problem if it was caused by that

i have the exact same problem anyone got an advice?
I found out what causes it, but not a solution. using a button on a bluetooth device to pause/play/skip/voulme etc, can sometimes cause the wakelock.

I also checked out my battery behaviour this night and was very disappointed. Although my phone was in flight mode and every peripherals and services shut down, today morning my phone was crying for energy. So I made a quick investigation in my power diagram and found out, that "Android OS" requested a wakelock during the whole power-on time. So I installed "CPU Spy" to check in which states the phone was really over the whole charging period. I couldn't believe my eyes. Although the kernel should do it's job good, cause most of the CPU times are in lower freqeuncy states, the deep sleep mode was never activated.
Therefore I installed an app called "Wakelock Detector" to check out which apps could cause that. I found out, that S Health had a big amount of wakelocks and also active-time, so the first thing was to disable S Health. After some minutes I checked back, but nevertheless still no deep sleep time in "CPU Spy".
So I searched around and found another one arguing about the wakelocks and that they could be the products of some programming issues concerning WiFi. The should be gone, after turning off WiFi and rebooting yout phone. And it seems that he was right. I waited some time and hooray, "CPU Spy" listed the phone state "Deep Sleep" the first time as an active state and also with the major active-time. So at least that was some step ahead. (I have to remark, that S Health was already unfrozen at this time, so S Health should not be responsible in any way.)
The next step was to reactivate WiFi, leave it on and set the phone on standby. After some time I checked back again the phone showed even more deep sleep time. So that was an improvement. I reactivated everything and waited some time... Deep Sleep all over the time. Can't figure out for now, if it was S Health, WiFi, or anything else that caused the wakelock for sure. At least the reboot helped. I'll check that out on a long-term test, maybe I get some further conclusions.
I was losing no more than 1% per night until three nights ago. I have also tried wiping the cache partition (yesterday) to no avail. "Android OS" is listed as the top resource hog, and it looks like it is not letting the phone sleep.
It looks like "keep awake" under the Android OS entry in the battery is going for the entire time the phone is on.
Suggestions?

Something isn't letting your phone sleep/doze.
You need the check which applications are running.
WiFi scanning is on perhaps?
Exchange services? That was my issue. I had to give up on using gmail for my exchange account and download Microsoft outlook for android.
Thanks I will check those. Wifi scanning is likely on, but that has been on for months now... not sure why the sudden change. May have to just wipe the phone and see what happens. Google maps, when giving directions on my car Bluetooth, has also started cutting off the last 30% or so of the voice guidance every time. Maybe a wipe will fix that, too.

Impossible to tell what's causing the wakelocks with root. Best you can do is educated guess.
something was holding your device awake literally the entire time

Well I ended up doing a factory reset. All was good at least for the first night. I will update and troubleshoot more if needed.
Bluetooth on?
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.
My battery lately has been draining really fast from doing minor tasks. 2-3 months ago I upgraded to the latest MIUI 11.0.4 and noticed a slight increase in drainage but nothing too concerning. For the past few days though, it has become really bad. An example is how today I charged my phone to 100 percent and within 8 hours it is now already down to 75 as I am writing this post.
What I did:
Charged it.
Left it idle for 4 hours
Browsed some Facebook feed for around 15 minutes
Watched YouTube videos for a total of 15-20 minutes
Left idle again for another 2 hours
Just now spent another 20 browsing some Reddit posts
I usually keep my mobile data as well as the WiFi connection turned off all the time and only turn them on when I need to use the phone. I don't have any IM apps running in the background all the time syncing messages except Kik and Snapchat for whom I've set a battery saving modes to close whenever not in use but again, like I said my internet connection is always switched off. I keep my screen brightness low all the time as well btw.
I usually charge it as soon as it goes down to 30-40%
Pretty sure tomorrow after a whole day of work having it sit idle and then doing some minor internet browsing its gonna drop to 30-40.
Here's a screenshot of my battery stats:

Not sure if this is normal as I remember it draining way slower than it does nowadays. I know that this phone is known for having a good battery life. Any suggestions on what I should do? Is there warranty for the battery in case it turns out to be faulty? I've been using this phone for a little over 6 months now.
I have terrible wakelock on 11.0.4.0.
Non rooted and I want to keep it like this.
Is it a common issue and should I go back to MIUI 10?

Hi, bro!
I had this wakelock in all versions (Android 8 or 9) I tried several times to find out which app does this, installing monitors made for it and so far nothing ... But yesterday I reset my RN7 and the wakelock didn't come back. I imagine it is an app that has not yet performed the initial configuration.
switch aosp(no gapps recommended)
i get 12 hours plus sot

Multiple apps. Of course I tried to fix it by deleting a couple of apps such as restricting the background activity in the most of the rest but I only succeeded to reduce the wakelock from 98% to 50%. The bad thing is, that if You do hard reset it's a temporary solution. Wakelock will return in maximum one month. So what is the solution? Returning to Miui 10 or AOSP rom if You want to run latest Android version?
