Android System High Usage

Hi guys,
Anyone have an idea what would cause my battery stats to have very high "Android System" usage all of a sudden. No new apps installed.
Thanks

I'm seeing this get pretty high as well. Starting to wonder... TW really limits the information in the Battery Status dialog. Hopefully we'll get ROMs soon that have more detailed information like I had in MikG.

Did you recently start seeing this? Or has it been from the beginning?

It has always been a bit higher than I am used to. I just grabbed the new version of betterbatterystats from here: http://forum.xda-developers.com/showthread.php?t=1179809
Hopefully I can use this to figure it out.

Please keep me posted if you find anything

System Panel works really well for me I found. Paid version is totally worth it, too.

Just another thought/question...
I am assuming since it is "Android System" causing such high usage ( I have 5% battery left and android system is 30%), that it cant be an app I installed causing the issue.
It has to be something that is either part of the stock ROM (I am stock, not rooted) or something core to the android operating system. PLease let me know if you agree with my logic that it cant be an installed app.
Just trying to find the root cause at this point or determine if I have to hard reset which I dont feel like doing.
Thanks again

The original SGS2 has an issue similar to this.
http://forum.xda-developers.com/showthread.php?t=1290020
They discovered with it that the processor has to ramp back up to 800MHz to do its pre-deep sleep tasks, in addition to taking longer than normal to do those tasks. So with a phone that woke up often to sync, even limiting the processor to 200 MHz with the screen off, it still spends a considerable amount of time at 800 MHz. I don't think they have a fix, but you can work around by limiting the amount of syncing the phone does while sleeping.
Don't know if this is related, since TMO SGS2 doesn't use the Exynos.

Thanks for the reply. My problem is that the battery usage for android system used to be 5% or less and now out of the blue is 25-30%.

Did you change any sync settings? Setting up an email account or maybe a widget to sync could do it. The phone has to do a bunch of system related tasks when it wakes up and goes to sleep, and those fall under "Android OS", so even if it is waking up to sync for an app, the system still has to do stuff, and more than usual when coming out of sleep. Like the other thread said, the original SGSII does all these things at a far higher clock speed than it needs to, and takes longer than most phones do.
I myself don't have the phone yet, nor do I have an original SGS2, but you could look up much of the same information the gentleman who wrote up the OP in that thread I linked to see if the issue is related.

I was so annoyed with this issue that I decided to do a factory reset. I dont think it helped.
So far after being off the charger for 2 hours....I sent 5 texts, browsed web for about 5 minutes. I am down to 87%. Display time is 46%, used for 18 min and android system is 17% with stay awake time at 3 minutes, and there are other items taking up battery at 5% or less like cell standby, android os, market
Does this seem normal, I never rememver android system taking up over 5% even with little usage. I am actually pissed because I would have thought that a factory reset would have helped for sure.
BTW, I am only syncing one acct, Google

I've been watching with betterbatterystats for a couple days now. I've got Skype running in the background so I expect that to use some battery and cause some wake ups.
But it has turned out that location services and updates have been doing a lot more, as much as 7000 in one day. They show up as something related to Maps, but I think that it might be Latitude. So I have disabled that location tracking. We'll see if it helps, there isn't much more using my battery. It is just something keeping it from deep sleeping.
If this doesn't work I'll look at other location apps like weather and such. I already uninstalled Accuweather after reading about how they transfer your location tracking information over the Internet unencrypted!

How can I track down my battery drain?

Leaving my OP in place, but I have rewritten the description with much more detail and pics here
http://forum.xda-developers.com/showthread.php?p=25401417#post25401417
I suggest skipping to there.
I am looking for general tips here. E.g., not asking you to diagnose my specific problem so much as give me ideas of what else to check or try.
Lately I have had unexplained (to me) battery drain. Yesterday I lost about 25 percent in an hour while the phone idled. It is not a constant thing, though. I can go an hour and loose 1 percent then loose massive amounts in the next hour.
Now, i have searched, but I have not found anything that applies to me.
I have:
Tried a different radio
Tried a different kernel
Reflashed my rom
Phone is entering deep sleep according to cpu spy
There are no unusual or excessive wake locks according to better battery stats
No apps are using a lot of battery.
I am in a low signal area at work, but putting the phone in airplane mode and dissabling background syn does not stop the drain.
Ideas?

might be your phone is loosing signal? i would check the battery stats in the settings menu to see if you have a poor mobile signal.

So I don't think I can blame it on that.

Do you have any exchange sync on your phone?

I do, and on reflection it is a possible culprit since I added it recently.
Didn't occur to me since it was producing no wakelocks and the battery stats did not showing as using much battery.
I shall turn it off for a bit and see if that helps. (unless there is some other way to test if it is the problem first.) I am off to the search button!

This is from yesterday when i set it down unused for about 90 minutes. The amount of wakes seems liek a lot, but it is similar to what i see when i have far far less drain, so I don't think that is the problem. I didn't get the app list screen, but out should screen as the only major drain with about 2 minutes.
I know it is shows poor signal strength, so immediately after that shot I put it in airplane mode, turned of sync, and rebooted. The battery continued to drain and graph had the exact same slope under those conditions. (Forget to get a pic though.)
Sent from my jitterbug using tapatalk.

System panel paid version with monitoring enabled is the best for tracking apps using CPU.

OK, still working on this.
To recap:
When the screen is off, and no apps are running I sometimes get inexplicable battery drain. This is occurring under conditions when I should be experiencing little or no drain at all. I say this becuase:
The screen is of and no bakground apps are running
the phone is NOT awake and IS entering deep sleep (as confirmed by cpuspy)
there are no unusual kernel or partial wake locks
there are no apps listed as using unexpected ammounts of battery
This is not a universal problem. The phone *often* behaves as expected. I can leave the phone off for an hour and see a 1% or 2% drain, and I am happy with that. However, sometimes, randomly, it goes nuts on my.
This graph from a few weeks ago shows what I mean. Look in the green box. The phone is sleeping, and the screen is off. The graph starts as a flatline, then, all of a sudden, it begins to drop precipitously.
Here is a graph that shows the battery dropping at the same rate whether the phone is awake or sleeping:
I have gone the following to try and narrow the problem down:
Done a completely fresh install of my Rom including a system wipe.
Tried two kernels (the aokp default and several relases of Franco's
Tried a different radio
Activated and installed a new sim card
I have come to suspect that the problem is network related. When the problem starts, sometimes going into airplane mode and back and/or toggling 2g only temporarily fixes the problem.
I suspect that something is happening with my connection to T-Mobile that keeps the network running and draining power. This is pure speculation, but it is all I can think of.
I installed juice defender (which I had not been previously running) and noticed the that, sometimes, it didn't turn of data when it should have. I also noticed the following two things happen:
I do not believe it is a rom problem, since if so, someone else would be reporting this. It might be an app problem, but if so the app is draining battery without a wake lock and while the phone is in deep sleep.
It is not exchange (as was suggested in this thread) since it continues when I ev my exchange account.
I have no idea what else to do or try.
Since it happens at random and takes a while to identify, uninstalling one app at a time to test for that could easily take months to narrow down a misbehaving app.
I know it is not a hardware issue since last month I got this:
That was with AOKP and Franco (earlier versions obviously)
I have google searched till my fingers bleed.
I am a long way form being an expert, and I suspect I may have overlooked something obvious.
Please, any thoughts??

Damn you definitely have a major issue and I don't know what it could be. But when my phone sleeps itstays dead flat with no awake bars, and drops 1% every 3 hours.

1. Calibrate battery
2. If you really wanna find the problem, install the rom with no mods or apps and run it and see if it still happens. Then add back each mod/app one at a time

While I appreciate your effort, this is remarkable unhelpful for the following reasons:
1. "calibrating" the battery is a myth and doesn't actually do something. Even if it did, it would not explain the symptoms I have described. I have been around xda long enough to know it is the knee-jerk reaction to any battery question, but it is not relevant here.
2. Since the problem occurs at random, and sometimes takes hours to show up, (For instance, last night I charged to full and tried to catch it happening. For 4 hours nothing happened, it behaved perfectly. Then I went to bed and it immediately started to fall and was dead by morning) and since I have over 100 apps, your suggestion could easily take *over a year* to follow. Believe me, I have thought about it, but I started this thread hoping for ideas that would allow me to avoid it.
Here is that chart for last night.
I had about 1 hour and 30 minutes screen on time with 65% left when I went to bed. When I woke up, phone was dead.

Mine often does that. But sometimes it doesn't. It is the fact that it happens seemingly at random that makes it so annoying and hard to track down.

I would replace the battery
One thing you haven't rulled out is that the battery itself is bad.
Have a friend you could swap with for a day, or at least long enough to see if the problem follows? If your battery drops on their phone that is also a good indication.

The thought has occurred to me, but unfortunately, no, I don't have a friend I can swap with. And really, since I have had the phone less than 3 months, the battery *shouldn't* be bad, but yeah, defective products happen.
If I cannot find any other cause I will likely order a new battery and see if that fixes it.

1. yes battery calibration does make a difference.
2. ok, so an app can't run a process at random? especially when you have "over 100 apps"? Run the rom stock and see if it still happens, or even run the stock rom/kernel. if you don't want to try this then why are you asking for suggestions? christ

You are incorrect. But, in any case, I DID calibrate the battery just to cover bases in the case that I was wrong.

We'll of course it can. That is kinda my point. If I go one app at a time waiting for it to "run a process at random" I am talking literally MONTHS of testing. I would have to wait many hours, if not days after installing or uninstalling an app to be sure whether or not it made a difference, then move on the the next. This is simply not an option. I started this thread in hopes that a realistic and doable solution might exist that I was unaware of.

I am asking because there may be a solution that I am unaware of that doesn't require me to put my entire life on hold for months. It is possible that there is no such solution, but I asked in case there was one.
Sorry to have put you out so much.

You mentioned you recently installed exchange sync. Did turning off sync remedy this or have you not tried disabling all sync features?
One other thing to check is the background data usage of your apps. You'd find this under 'data usage' and make sure you enable the wifi tab so you can see data usage on wifi.

My battery also drains at a rate similar to yours however I'm on the CDMA version. Hopefully you can figure out what's going on with yours.

Battery life gone from 2 days + to less than 1 day.

Hi, about 4 days ago the battery life in my phone vastly dropped, with no 'actual' cause. Previously it had been lasting a good 2 days with an hour or two of usage each day, and now it drops 30% in the matter of hours without any use. It's becoming unusable, as by the time i take it off charge at night then go to sleep, it will then be almost dead again by the morning.
I've tried restoring it to an earlier point where it didn't have this problem but that hasn't made a difference. I've also got two batteries and they both have the same problem.
Main battery usage -
Android OS - 44%
Screen - 11%
Voice calls - 8%
Android System - 7%
Has anyone got any ideas?
Thanks in advance

Android OS - 44% ???
If it was my phone I would suspect that there is something running on the background.
Did you have the OS around 44% before this problem?

Agreed.. and I was the same until I discovered that the App "Android System WebView" was killing my battery, just uninstall / Disable it.. reboot your phone and it should be fine. The downside is.. Webview app is a part of Chrome, so youll probably have to change your G3 browser... I switched to Firefox.. and Its great now
Are you uising a Stock Rom or are you Rooted.. what have you been downloading lately.. Sadly, the latest "Google Play Services" updates, are pretty heavy, although I dont know why.
Another thing to check .. Open Settings > General > Smart Cleaning > Emty any Temp files > Reboot.
As a last resort.. depending on its age... your battery could be dying, theyre about £15 ($20) on eBay.
Hope this helps, but others may have better suggestions than me..

No, it has always been around 20 percent i think, maybe a bit lower. I can't remember for sure though.
Also I forgot to add that I'm using Android 4.4.2

My phone has been rooted and has CloudyG3 installed.
I Haven't really installed anything recently, I've only just updated apps.
The Battery shouldn't be dead as I've got two of them and they both have the same problem.
And finally - There weren't any temp files or cached files to be emptied.

Sorry to say because I use my G3 as my daily driver for work then I can only speak from using a stock rom. Never used CloudyG3, but does it use Play Services or WebView. You could ask this question in the Development thread, but I dont know enough about Cloudy to help.

Crazy Android System ?!

About 3 days ago the battery drain on my Nexus 5X went crazy. I found out that the "app" Android System do not let the phone sleep and keeps it awake all the time. That is why the phone can not even get into doze mode and drains about 8% per hour when the screen is off. I tried restarting the device and also force stopping the Android System. Both without any succes. Do anybody knows what to do with it? Or should I just wait if it will go back to normal? I do have screenshots, but the XDA will not let me post outside links...

Interested about that.
Ur screenshot may be useful, host them in a site like imgur and replace dots by other letters.

Well just delete the two underscores and the "dot" thing

I am having the same problem. It occurs randomly, most often when I have just charged the phone and removed the cable. If i am correct, a wakelock under the name *backup* is holding the phone awake, it might be the same in ur case. I've done a research on this, turned out this is unfixable unless you have some sort of wakeblocker, which my current rom lacks of. I tried using xposed with its modules, but it gave me a ton of bootloops and i gave up on it. The only temporary fix for me is to reboot the phone. Until it happens again. No clean flash nor anything i have tried seemed to have helped. I even tried disabling all services and receivers from Android System, no luck again. That is one hefty problem

I have exactly same problem with wakelock. It happens only after charging. Everything is OK after restart.

It has happened to me sometimes on my old HTC One X and I think it happened also once on this 5X, but it was just for about a day or so. It disappeared itself with time, I didn't do anything with it then. Now it's been 6 days, I have to charge the phone twice as frequently and neither the reboot nor the force stopping everything works. I really don't know what to do in this case. Also this phone isn't rooted yet, so I can't just flash the system again as on my old HTC... I'm still hoping it will disappear by itself asap
But do you anybody have any other ideas what can I try to do to stop that crazy system app?

same problem here...
had the phone about 350 hours with no restart and i thought i would give it a reboot..
same think happened...android system was going from 2% to 20% in a matter of hours..
installed an app called GSam Battery monitor..showed me the phone was not going in deep sleep (Doze mode) at all...
here is an attachment if anyone can understand better than me..

I posted a similar thing in the battery life thread. Very odd really as I've had the phone a few months now but it also only started with me a few weeks ago. Really can't think of a trigger for it... I doubt the April update would have been significant enough to create an issue, but who knows.

Exactly. After about 4 months of working excellently and about 400 hours without restarting, after charging it's immediately goes into this "mode" when the Android System won't let the phone sleep. Even restart didn't help me, but now after 3 restarts it goes to normal. One bad thing... after every single one charging, every time I put the phone on the charger it goes crazy again and I have to restart the phone after every cutting of of the charger... it makes me really angry when the phone is only 4 months old and even the "okay" battery life isn't that good on this phone... God I just need to find a solution, that's insane...

THIS!!!!
the phones battery life was a big "ok i can just play a bit less so i can get through the day and IF anything happens i know it has fast charge so ok"
nowadays i have to reboot after EVERY charge....
p.s.
anyone that faces the same problem but WITH mai's security update? do we have any hope that it will fix that problem?

Not sure if it's a one-off, but I decided to uninstall the game "8 Ball Pool" by miniclip as it appeared on my battery usage stats when I'd not opened it in days. Since then, even after a recharge, the phone seems to be going to sleep as normal.
I'll monitor to see how things go but perhaps it could genuinely be a rogue app. It's a little disappointing that doze wouldn't block the keep awake requests - I thought that was one of the main purposes of it.

The same issue occurs for my Nexus 5X: after device disconnected from a charger, Android System process starts to keep device awake until next restart. As I understand from comments above factory reset does not help to solve a problem. Has anybody met the similar problem with custom ROMs/kernels?

It started with the latest update I think. It hasn't happened once ever before. I hope they already know what's happening and with the May update it will be gone. I don't think there's any other solution when you don't want to flash custom ROM and stay on stock... :/ we have to wait.. :/

Hmmm, sorry for offtopic clarification... as of now I'm little bit confused about Android versioning, especially it's unclear for me: whether you mean as latest update: 6.0.1 or april security patch or model build number (like MHC19Q, which is currently on my device)?

I guess it must be April security patch. Some kind of problem in the Android System app that comes with the security patch. I don't really know in this case, but as I've said, it hasn't happened once before the April patch

I rolled back to MHC 19J. The April MTC19T Build cut my battery life in half. Android system being the top culprit. Deep sleep never going over 80%. Horrible idle drain. Would drain 15% over night while i slept. Exact same setup as before, no new apps. SOT went from about 5 hours to not even 3.

MTC19T is May update. I've updated my device to it yesterday and the issue hasn't been fixed yet: a device is still kept awake by Android System after disconnecting from a charger. @ScumDroid, could you please confirm there is no such issue on MTC19J after rolling back?

Same issue. After running it for few months flawlessly, the Android System is keeping the device awake and only restarting it solving the problem temporarily. Charging the phone again starts the wake lock..
Most disappointing is it's the 'Android System' that causing the problem. If any app/game is linked to this, it should have been appeared as the culprit but unfortunately it's that 'System'.
Waiting for solution.

Samsung users are having the same problem.
I have found something on my Samsung Galaxy S6 in regards to 'Android OS' killing the battery. It might be the same for Nexus users, I've confirmed this on a Moto G 2015 running the latest MM update and on a Samsung Galaxy S6 Edge. By latest update, I mean the April security patch.
Check this and this.

MTC19T is May update. I've updated my device to it yesterday and the issue hasn't been fixed yet: a device is still kept awake by Android System after disconnecting from a charger. @ScumDroid, could you please confirm there is no such issue on MTC19J after rolling back?

Android 11 update - serious battery drain issue

Hello,
2 weeks after Android 11 update, my pixel 2 xl started to feel hot and the battery was discharging quickly. On Google help, many people were in my case, and many of them mentioned about unstalling Tunein. Which I did, then my phone stopped to be warm but this didn't stop the drain issue. What I have noticed is that if I don't touch my phone, the battery acts as normal, slow discharge, but when I use it, meaning when the screen is on, the battery just discharges at a crazy speed. It was not like that just before the Android 11 update. Anyone got this problem and found the reason / a fix ?
Thanks

I am having the same issue. An have not found a solution as of yet. I thought it may be the Pixel Launcher. So I changed it to Nova Launcher with no change.

Yes, strange. Mine gets a serious battery drain from 100% to 50% in a short time, even when I don't use it. Then below 50% it is very stable as long as I don't use it. Never experienced this before.

I have the same problem. before that, I was calmly getting 4-6h SOT After updating to Android 11 as lucky as I get 4h SOT. Mostly, however, I have 2.5-3.5 hours. The standby time seems ok, Only during use the battery disappears very fast. ? In my free time I will try the factory reset.

I think i got it...
Hello gentlemen, i got this problem with october update in particular.
So, digging in a google forum i found a user who recommended to install an updated version of Android System Webview (maybe you should download it from apkpure or apkmirror) , Carrier Services and.... uninstall Tune-in (yep... the radio app)
I don't know which one did the trick... but it just did..
I hope it helps!

Can you comment which versions of carrier services and webview you installed?

Sure, i installed webview 86.04240 and (there was a mistake in my prev post) Device Health Services 1.17.0.331553323.
Anyway, i got 2 webview updates since then... so, just install the last one... if you got auto-updates enable you should have your problem fixed by now (i guess that happened to the op).

thanks for the info, unfortunately I checked and I have exactly the same version of the application installed. the problem with the battery remains. the strangest thing is that I have no problem with idle drain, but when used with the screen on, the phone uses almost twice as much energy as before ?

I have the same problem, idle drain is ok, but whenever I use the phone, the battery drains very fast.

finally someone with the same problem. did you do factory reset before updating to Android 11? Because I don't, and I think I'll try to do it.

NO, i didn't do a factory reset because I have seen a lot of people (online) doing it without success. You can see this thread here on Google support, over than 580 comments today...https://support.google.com/pixelphone/thread/70445129?hl=en
But apparently some people fixed the problem with a factory reset...

I had the same problem and it was a new (at least to me) Google program called "Digital Wellbeing". I had to turn it off, which wasn't a straight forward proposition. I even "uninstalled" which just uninstalled the updates and they came back.
I don't recall exactly all the steps I took, but I now have my trusty Pixel 2 XL back to it's previous battery usage. Which is excellent for a three year old device.
Anyway, turn it off, take away all it's permissions, and do everything you can to shut it down. I was almost ready to root my device just to really get rid of it.

I disabled digital wellbeing, stopped the permissions, and uninstalled the update on the play store, but it didn't fix the battery drain...

A few days have passed and I can see a significant improvement. Honestly, I don't know what actually helped. some app update or maybe something I did, but there's a significant improvement.
In general, I would like to remind that from the update to android 11 my battery was tragic but only when using it, there was no problem with standby.
I was barely able to get 4 SOT hours. Now I can safely exceed 6 hours.
The only modifications I made were:
- leave beta program of digital welbing and its complete shutdown app
- disabled wifi scanning
- disabled Location service for emergency calls ELS
Since then, battery consumption with the screen on has dropped from 25-30%/ h to 12-16%/h. The phone is like new again. In addition, everything works very quickly and smoothly. ??
