Why is Android System taking up 60% of my battery?!?!

hey folks,
i need some direction with a particular problem...
check out the attached screenshots. why is the "android system" percentage so high?? i'm still in my learning stages, so i'm not sure how i can get rid of some of the processes, which i know are seriously harping on my battery life (which is great, but it can be much better, ya know?)..
any help would be appreciated!

It's so high because you were probably using your phone for the two minutes it was unplugged. Therefore, android system took up the majority of the battery used so far (which might be next to nothing since it was only two minutes).

Get a good task manger. You can exclude apps you want running and kill ones you don't. Also, there's a lot of battery optimization in rooted roms.

well, unplugged, it's usually 30-40% anyway. that's waaaay too high, especially since i keep hearing it being 2-3% here on the forums.

i don't really like to have a task manager. i'm wondering what kind of processes are useless. or maybe it's my dc rom that's letting them run?

Is it doing it all the time or just once in a while?

well, right now, it's at 4%, but i haven't touched it to use it, and it's unplugged. but, yesterday, i was at work, and i only used it a few times to text, respond to emails, check twitter (cyanogen stalking lol), and check time. it was at 30-40% at those times.

im new with android operating system so this might not be the entirely correct .. from my experience once you use the phone for multitasking and not closing the applications .. thats when that happens.
it also seems to happen when your batteries critically low and u click on the battery usage prompt that comes up.. hope that helps..

Battery life, android OS at 40% normal?

Sorry if this is the wrong section, but it seems like the only section specific to the Captivate Glide.
My wife's Glide is stock, very few widgets (google voice, battery, stock clock) and Android OS shows up at 40% when the phone is idle overnight and during the day during use. She has fb set up on socialhub with only contacts synced, 2 gmail accounts, and Touch(used to be pingchat). wifi is enabled and connected for most of the day. bluetooth is on too, but only connected when in the car.
I don't think it's Touch since I have it on my Atrix and Android OS is at 2-3% for me.
Any ideas?

do you have apps that can access your location? (weather apps, maps etc.) If yes, you may wanna go settings > location and security > and then uncheck "Use wireless network" in case you have not done it yet.

I don't think that's it. I have location enabled on my phone and have a weather widget. The wifes phone does not have a weather widget.

She might have some app that is are using way too much cpu, try doing a factory reset and check the usage, mine is currently %17.
Also the facebook app is a notorious battery thief. Battery usage percentage isn't standard for different people, if she's not using much features, the majority of her battery will be used by the OS since there is nothing else to use it.

Wouldn't phone idle be the max usage? For my Atrix phone idle is at 70% or so when I barely use the phone and Android OS is 3%. I can try disabling facebook overnight to see if the Android OS usage goes down.
The battery life for this phone is ok. It hits ~30% or so in the early evening, meaning we need to charge the phone if she goes out that evening. For my Atrix the battery doesn't hit 30% until midnight under light usage conditions (no games).
Is there an app or logcat keyword to filter to break down exactly which thread/process is using up the CPU?
edit: nm, going to read through this first

From looking at the wakelocks with BetterBatteryStats the likely culprit for the battery usage is the facebook chat portion of the fb app. The wife has many contacts in the chat, so it's probably polling quite a bit. For me the wakelock count for fb chat is fairly low. fb chat is a must for the wife so I can't disable it.
Also in the process screen I see several kworkers with high usage...not sure exactly what's causing that.

so for whatever reason the battery drain is now more acceptable even though the Android OS usage is still at ~50%. Could be the fb update, but the good battery performance occurred before the fb update.

my infuse 4g has a battery drain because of fb.....it's always the next thing that is draining the battery (i hope to get screenies). I just force close fb (or set refresh interval to "never") when I am done using it....
I can't say that this is same as yours but it may be a thing to look up.

From the betterbatterystats output, I'm pretty sure the high Android OS usage is software related and specific to the stock ROM. The radio and wifi battery usage are normal.
I have no clue what the kworker processes are doing when the phone is supposed to be idle. Overnight my Atrix is 68% idle, 12% cell standby...android OS is 2%.

Idk you could try when putting it idle turn of Bluetooth and wifi and the data network this could help see

BT is already off. I could turn off both wifi and data network and if it turns out that is what is causing the battery drain (does not seem like it)...then what? Don't use wifi and the data network? It seems like there's little we can do as an average user to fix the high Android OS usage when idle. It does not seem like high kworker process usage can be fixed by TiBu or other simple fixes from a user.
Another update from Samsung, custom ROMs, and other dev fixes on xda seem to be the only options.

You need to find the source to find a rom that will repair this sometimes an launcher can make your battery die faster I know that Facebook and the browser use a ton of ram I have a stock app on my phone called application manager and I can stop apps that are using my ram

are you using a custom ROM? I'm kinda new to Samsung devices, but I know HTC's Sense was a battery hog, so I'm sure Touchwiz is the same.
Try installing CM9 or AOKP build 37.
I have AOKP Build 37 installed and my battery lasts the whole day.

Wrong section by the way. It should be in Q and A, not general.

Try a different rom, tfe16 has been the best yet for me and agat has an updated version coming soon. Also dont use 4g, wifi, gps etc unless you need them. Solid black background and lockscreen, inverted apps and dark settings. Ditch facebook twitter and crap like that that updates and burns battery.

Basically if you don't use your phone, your battery is awesome...

Go outside and play instead of sitting on your phone youtube'in

Whatever guys that stuff applies to any mobile device. Turn off stuff you arent using, ditch the live wallpapers, worthless apps, and status updates and you get more battery life. You want to surf, download, stream then by all means toggle wifi or 4g on but no reason to leave it on while you are doing nothing. Same goes with gps and bluetooth.

With the exact same setup I have now, I get 20-30 hours on gingerbread. On cm9... I get five.
I don't leave wifi on. Don't leave 4G on. Usually have a minimal screen on time of around thirty freaking minutes.
Don't tell me that I need to cripple my phone (i use it for business). Because there is something clearly wrong. I suspect it is the kernel. I don't have unnecessary apps installed (aside from ones that work great with gb). Don't use a live wallpaper. I do however, refuse to disable auto syncing.
There is clearly an issue with ICS.
I'm not going to turn my smartphone into a paperweight like you suggest.

Not using stuff you don't need is hardly crippling your phone its smart use. I never said anything about turning off auto sync either but you should be selective what you sync. Google plus, drive, picasa all sync pics and other crap in the background without telling you and it kills your battery especially if you are in a bad signal area. Figure out whats draining your battery by using better battery stats and apps like system panel lite http://forum.xda-developers.com/showthread.php?t=1179809
Honestly though try another rom and do a clean install. If you get 80% less battery life no amount of tweaks will fix it and the ics leaks are good now. Several months ago the battery life was half of gb and now they are about the same.

Trust me, I've done all this. I have the same battery life with ICS now that I did a couple months ago. Going to stock, it is wonderful. Had my battery tested by sprint yesterday, it's fine. So, i'm just waiting for a real kernel and hoping for the best.
Sent from my SPH-D710 using xda premium

Turn off LED notifications they're a known issue for wake-lock.

I get terrible battery life on alpha 5. Change to a stock kernel might help.

Kobridge's tweaks http://forum.xda-developers.com/showthread.php?t=1668853 along with Badass Battery and CPU Spy have helped me trace battery drainers. Also wholeheartedly agree turning off apk's and functions that are of specious value helps greatly ie.( auto rotate, auto brightness, dialing back on sync; etc.)
Good luck

Possible ATT JB update battery drain fix - root only

I had been getting some higher battery drain with JB than I was with ICS, both were on rooted stock ATT roms. Early on I had posted that it was about the same as ICS, but after more and more use, I was starting to find that it really wasn't. I was consuming about 5-8% per hour idle and 10+ while actually using it. The idle bothered me the most because, obviously, using a phone will drain the battery
Two things have stood out as the high consumers: Media Scanner and poor signal.
To address the media scan drain, there have been suggestions to change CWM settings to backup as .tar rather than default .dup. This ONLY works if you re-do each nandroid that was a .dup as a .tar, delete the .dup backups, and clear the unused backup data through CWM. This removes the blobs folder files which will be in the thousands.
To address the poor signal drain, I flashed the UCLH9 modem (see modems thread in the development forum). Better Battery Stats is not showing any drain caused by poor signal, and this is also reflected by actual usage, the signal is simply... better.
Consumption is marginally higher than on ICS but not nearly as high as I was experiencing. If this has already been covered, my apologies for eating up server space...

Could you alternatively put a .nomedia file into the clockworkmod folder on the device? Would that prevent it from scanning that folder?

Well I'm bone stock and not rooted, I have no backups and the media is eating my battery like mad since the update. I've killed the process several times but it starts back up on its own. The only way I know to fix it will require root.

I have all the att and Samsung bloat frozen via TiBu.

Trust me, something is there. I never had the chance to figure out exactly which app it was though. I have a feeling that it may have something to do with a Samsung app.
I would suggest using OS Monitor from the Play Store. Make it show all system processes and see if you can dig deeper into it.
Edit: Also, here is my humble opinion too. People keep wanting new and better features. Well, that always comes at a cost. Just remember that. The iPhone boys are learning that the hard way too.

I agree with that sentiment... I'm considering reverting back to ICS but the smoothness of jelly beans is too enticing.
after making these changes yesterday I got a 40% battery consumption over 9 hours with average use which IMHO is plenty.

Solution is to reboot the phone OR unmount by going into settings, storage and unmount the USB there instead of from the notification bar. I think this solution works but have not tried it myself.

rebooting whenever the os gets out of hand, or unmounting the SD card, is not a viable option IMHO.
my post was directed toward root users who have cwm installed and are experiencing the media drain because of the blob files. the modem change I tried because all the reliable jelly bean ports seem to use the H9 modem. a weak mobile signal is detrimental to battery life, as is a weak or intermittent WiFi signal.
believe me, on my rooted phone, these two changes made a real and noticeable improvement in battery life in JB. I've gone half the day today on ICS and half the day on JB. battery consumption is now within the range I had on ICS.
one the one hand, I believe that some increase in consumption is due to the "omg I has the jelly beans and I'm going to use the bejeasus out of my phone" factor. I also believe that a good number of fixes and patches are simply a placebo effect. BUT, my phone had been getting hot and tearing up the battery due to signal searching in areas where it had been fine prior to the update. heck, we have an att tower within 100 ft if my office, I typically pull 69-70mbps at work. on the k3 modem I was regularly dropping data or losing LTE. not anymore.

Un mounting then re mounting seems to have worked for me the process can now be killed!

[q] at my breaking point with battery drain

I know this horse has been beat to death, I'm just hoping I can get maybe one bit of info that will help me resolve this issue before I just swap out to another phone. I really don't want to, but I'm just so sick of being chained to a charging cord all day. My phone should be able to hold a charge for at least 1 day, I don't even use it that much!
So with my little tirade out of the way, let me give you the facts I've got a Samsung Galaxy S II/SPH-D710, and the battery just drains down so fast, and the phone's barely 6 months old. I've downloaded numerous process monitoring apps, designed to see what's going on, and they all point at WiFi being the culprit. The phone never hits deep sleep because the wireless is keeping it awake. Sure enough if I turn WiFi off and I go 3G/4G all day my battery is fine. Problem is I can't get to that next level and find out what program or process is causing the WiFi to be on all the time. Even more frustrating, every time there's an upgrade like FI27 or FL24 which I'm on now, the battery works fine for a day or two. Then something kicks in and destroys the battery. My thought is it's got to be an app, I just don't know which one.
So before I kick this piece of **** out the window, I was hoping someone could please help me figure out what app/process is the cause of my battery drain.

Get DS Battery Saver. It will force all of your stuff off when you turn off the screen so that it will go into deep sleep.
Sent from my SPH-D710 using xda app-developers app

Get a new battery?

Apps, batteries, ics vodoo it's a host of things that can solve your battery drain issue. Being that your phone is 6 months old I have to rule out the battery. The fact that your on ics is going to be main culprit, stock ics was not the best at managing battery use. There's something revving the crap out of your Wi-Fi, while Wi-Fi is on even while your screen is off there are processes going on in the background that are using Wi-Fi to send receive, update, sync, you name it and all you need to do is pinpoint these processes.
Some apps in the play store can help, but some of these apps can consume battery also, so it's best to delete it after troubleshooting.
If your phone is working properly and your not a social media junkie while it sleeps it should not be using any battery at all, just enough to keep your processor awake.
I keep notifications are sync off on my phone, while I'm out and about I'll check email or do a quick sync if I want to check for some incoming whatever. Most of the time I want info on my terms, not every minute with chimes beeps or lights flashing.
If you use google maps disable background location reporting, location services just use "location and search " disable Wi-Fi and GPS usage for location services.
This is a start, but I recommend Jb ga10 stock/rooted to give your phone a stable os.
I run stock/rooted Jb de-bloated with minimal apps, no games (all the games I like are on my Galaxy Tab 10.1) I use my phone for calls........... navigation and media player while driving. I get 16 to 20 hrs on a charge.

I get about 20 hours on the Vanilla RootBox JB ROM. YMMV. I also had terrible battery life on the stock ROM and every other one I tried. This is the first ROM that's bested 10 hours. Again, YMMV.

what rom are you on? tw? cm?

Have you used Better Battery Stats? Or the JB release candidate GB08?

Not to raise the dead, I've just been busy, but this is still an issue for me. I upgraded to JB GB27, and I love the GUI, it’s such a step up from ICS. But I’m still getting **** for battery life. Yes if I use DS Battery Saver it works and I get good battery life. However all those programs cause flaky restart issues. The phone will just restart for no reason. More importantly it’s not getting at the root of the problem.
IRL I’m a computer tech and I can’t just let this go, as previously stated I’m tired of being shackled to the phone charger. I’ve swapped in a new battery, it’s not the battery. I even turned on the setting “Keep WiFi On > Only when plugged in”. That did improve the battery a little, but I still can’t make it through the day without being charged. I’m on the phone maybe combined 30min of phone calls, 30 min checking email, and an hour or so of miscellaneous watching video etc. I know heavy users that are on their phones all day, or let their kids watch Disney movies all night. I’m not that guy, I’ve had numerous cell phones and never have I had one that couldn’t hold a charge all day.
I will be diligent in monitoring this thread, please give me your troubleshooting tips and I’ll report back with the results.

Ive noticed no better or worse battery between being rooted/custom rom and stock not rooted. However my phone gets about 16 hours on average. My friend has an epic as well and gets only 10 hours. I feel as though it depends on the user and apps. Facebook is a silent killer. As is any app that uses backround. Best setup ive had so far is billgeryans Quattro Rom with ds and greenify. I pulled a whopping 25 hour minimal use before charge and 13 hour heavy use day.....

With titanium backup. You can also install greenify. It puts your apps in hibernation when your screen is off. So basically it's like freezing and unfreezing. Tbh I think it's better using greenify.

titanium can and you can create a widget to do it easily per app.
or
app-quarantine in playstore
or what I do:
shell commands usind connectbot widgets with a command like this:
pm disable-user com.facebook.katana
pm enable com.facebook.katana

so my 2 cents:
1) get a second battery and charger.
2) betterbatterystats to identify "bad" apps and either get rid of them or deal with them.
3) "autostarts" app to stop crap from auto starting on boot that you don't need running as a service.
4) dim screen! huge huge savings. keep it dim enough to use the phone.

Battery issues well I have a solution that won't solve but greatly helps. It's called greenify. It puts all running apps in hibernate mode. It's not like a task killer that just screws things up. U can choose what u want to hibernate and all that jazzy stuff. It's worth a shot. All in all if you want a bada$$ battery efficient rom go with wcx stock rooted rom. It's simply amazing. Hope I was at help

Check out greenify if you're rooted. It removes all currently unused apps and processes from memory, essentially putting them into deep sleep. That combined with ds battery saver and watching your wake locks will drastically improve battery life:beer:

Okay so does Greenify do this freeze automatically, the interface is a little clumsy. I appreciate all the help guys.
