[Galaxy S II General] Sleepycat3:
Your usage is quite good when the screen is on. Usually when the screen is on, you can see the graph dip down. Have you tried signing out of Latitude in the Maps application too?
[Galaxy S II General] Vahooli:
yeah bcz i dont use latitude ever... the bad thing loose 5% per hour when i didnt use my phone (sleeping ) ...
[Galaxy S II General] Vahooli:
what is android system process? its 30% ...
[Galaxy S II General] Pfeffernuss:
It's a keylogger service running in the background continuously tracking your every move and what you do with the phone. Twice a day the data will be uploaded to a server in China. Better keep an eye on your bank account as they can also detect your username and password from every app/account on your phone. I think you installed a rogue app and would personally be very very afraid to use the phone right now.
[Galaxy S II General] mrbusy24:
True, it's malicious software. You can kill the process by opening a terminal on your mobile, type:sudo kill -1 and press Enter
[Galaxy S II General] daraj:
Definitely deserves a Thanks for this thorough description. :cool::cool:
[Galaxy S II General] Vahooli:
hey thanks all for answers.i get whts problem ! all problem relate to dr battery widget!! i delete it and my usage get better.

but my Android System is about 12 % . is it normal ? whats this ?
[Galaxy S II General] Pfeffernuss:
Maybe it's worthwhile to read this topic. A lot of things are explained. The level of usefulness at the very end is rather limited though. The quality of the posts drops rapidly.
[Galaxy S II General] jp.salminen:
I've got 29% for the Android OS process and Android System process is at 20%. Guessing it's about right.. Very light usage and idling most of the time (on holiday atm :D). Battery holds up little over 2 days :) And using Juice Defender Ultimate (2,19 multiplier atm :cool:).
[Galaxy S II General] Vahooli:
thanx for ur guide.but first post in this topic is about android OS and my question is about android System. anyway thnx.

[Galaxy S II General] iwang:
My display takes off 70%..the rest including aos is less than 10% each...but still my battery drains pretty fast..10% per hour..is it because the phone is brand new? display set at auto.
[Galaxy S II General] Disfected:
The display will eat most of your battery if used the most, especially if you use auto brightness.
[Galaxy S II General] iwang:
Yeah I tried to go minimum now..my dell streak stays on auto, but stay longer on battery...strange..

Is it because I root the galaxy with cwm yesterday? Maybe wrong kernel? Still on stock rom.

[Galaxy S II General] chiggah:
Hi guys

I am on Cognition 1.5.1 with Speedmod T40 and experiencing high Android OS usage which is chewing up my battery. The phone was pretty much on idle/light use, but I do turn on and off the display often though (not power up/down). I do not have many applications installed - just basic ones like Facebook, Watchdog, betterbatterystats, battery monitor widget, imgur, Skype, Talkbox, Viber, Whatsapp.

I have also just calibrated the battery by charging full, calibrated with app and now discharging

Anyone able to help? Something is definitely going on and im unsure what it is. Please let me know if you require more screenshots

Last resort is to switch to VR 2.5 with speedmod or ninphetamine
[Galaxy S II General] rdy2go:
Nothing like this happens on my new galaxy tab 10.1, galaxy s and s2 are the only devices with such behavior I.e. High android os
[Galaxy S II General] Neo.:
Its a software issue not hardware
[Galaxy S II General] Shafty:
Desperately need some help on this please. I'm experiencing the android os bug big time. Had phone repaired by Samsung over a different issue and since they returned it my android os has gone through the roof. To try and resolve the issue I rooted the phone again and installed the Miui rom as this had previously given outstanding battery life. However, despite wiping everything as per the instructions, the android os bug is still very much present. Anybody have any ideas?

These images are from a 5 minute period. Please help.

CPU spy :
[Galaxy S II General] AndreiLux:
You'll have to wait for Samsung to fix it.
[Galaxy S II General] Shafty:
Check this out! Look at these battery charts. No CPU access at all when plugged into a charger and I've been using stuff during the flat period too. What does this mean? Anyone?
[Galaxy S II General] Shafty:
Don't want to hijack the thread but these are taken about 15 minutes after unplugging the phone. During this period I didn't even touch the phone, the screen was off and it was just sitting there. Yet android os has gone crazy again. Why?!? Anybody help me? Please?
[Galaxy S II General] Molitro:
Yesterday, tired as I am of my S2 eating twice the battery my S drained while idle, I wiped and flashed the stock KI3.

I didn't configure anything and left it the night. The Android OS high drain wasn't there.

Now I configured the gmail account (and did nothing more), and puff... Android OS at 50% within a few minutes.

I'm gonna deactivate auto-sync to see what it does, but samsung better fix this...

Edit: Nothing. Android OS still going up even without auto-sync.
[Galaxy S II General] Shafty:
I've just done a full wipe and reinstalled a rom but to no avail. This problem is transcending roms so it must lie deeper. What else can I format in cwm without bricking my phone?
[Galaxy S II General] AndreiLux:
Stop wasting your time, you can't fix it. I'll write a new thread on everything we've learned from these past few months in a moment.

Hello,

can I get this chart with a Samsung Rom, too or is that exclusive in the MIUI Rom?

[Galaxy S II General] samH4Sung:
i reboot my phone once a week or mainly when the RAM bar goes around 500~600MB/837MB so i just reboot it and its back down to 200~400MB/837MB.

Also make sure you stop UNIMPORTANT APPS from running in the background. Those will surely eat your battery life
[Galaxy S II General] Amritttt:
Same here I have to charge my phone twice a day.
[Galaxy S II General] harvey007:
Possibly this will *solve* the problem...

Hi, first of all, I am not using a GS II, I have a Droid Razr but I am experiencing similar problems where Android OS goes way up to 40 - 50% usage without me doing anything at all. I did several factory resets and tried to pinpoint the problem, and *I think* I was able to isolate the problem. I am not 100% sure, but you guys can try it as well. Try turning off the location services from the following:

Settings --> Location & Security --> Use wireless networks (uncheck this)

Turning this off brought down android os almost immediately. Seems that the location service is constantly using the networks to triangulate and identify your location.

I hope this helps :)
[Galaxy S II General] wcg707:
Add this to the cause of battery drain. Dlink DIR-655 will kill your battery within hours. Whether you on Stock or Mod rom, it doesn;t matter. As long as you are running android, then it will kill your battery unless your wifi is off.
[Galaxy S II General] cc999:
OS usage

I have notices a few things:

1 - DEFINATLY the Dlink routers suck the power, I have a DIR-855 and Netgear 4000 and I see a big difference.

2 - Firmware also affects the OS bug. I finally found the optimum combination:

PDA: I9100XWKK2

PHONE: I9100XXKL1

CSC: I9100XENJ1

Tried the KK5 and GPS lock was terrible.

With above I am getting stellar battery life. OS settles at around 9-11%.

[Galaxy S II General] buzzboy:
Insanity Rom has been awesome so far with regards to battery life. Wifi is my biggest drain, but I'm always using it, and is set to always on. But overall, I'm very impressed.

Using the rom with Siyah 2.4.2 and the 2nd core App, which is a marvelous combo.

Regards
[Galaxy S II General] zkyevolved:
I'm starting to have this issue, I'm at 40% Android OS, 26% Display, Android System at 11, Cell Standby 6%... The rest is soooo little.

What can Android OS be!?!?!?!?! In 16 hours it has 2h8min12s. Widgets? What type of background processes can this be?
[Galaxy S II General] borchgrevink:
First things first: I have this issue myself. Just wondeing, could this just be another way of showing real battery consumption?
[Galaxy S II General] Gnarfsan:
My battery usage went crazy today. The Android process was eating 1% every 10 minutes. It turned out to be my case holding down one of the buttons because it wasn't aligned properly. Sometimes it's not faulty software...
[Galaxy S II General] Manitax:
I will give it a try.

Edit: Seems to be good now.

Thanks!
[Galaxy S II General] DaKlown:
I have noticed this to but nobody seems to believe that the issue might be something with google accounts. I can do a soft reset and side load as many apps as i want and android os sits below 5% and I get great idle battery. Even if I add other syncing apps such as facebook and twitter without adding a google account my android os never goes above that range. As soon as I ad a google account android os skyrockets into the 30s and 40s. I have reproduced this a number of times but I cant figure out what in my google account can cause this...

There is a lot of useful info in this thread but one problem that this thread does not mention is the fact that if you use a custom kernel instead of stock the android os problem is masked somehow and most of your battery usage in stats then is attributed to the display. Also apps no longer show up in battery stats unless they use a lot of battery. Its almost as if the info is garbled up and distributed among the top stats....
[Galaxy S II General] swiftden:
I only have high AOS if my data is on. If it is turned off its very low.
[Galaxy S II General] mchu6am4:
Didn't know this thread existed but mine is around 70%.... There's lots of pages/discussion on the issue but has anyone found a solution and if so it would be great if the first post is updated accordingly please...

Btw, I'm running miui ROM
[Galaxy S II General] tarpek:
Use siyah kernel...
[Galaxy S II General] mchu6am4:
I am...using latest version and it's still at 60%
[Galaxy S II General] Pixiewave:
I went into settings -wireless networks - mobile networks -

toggled mobile data (unchecking it and then checking it again),

toggled roaming (checking it and then unchecking it again)

I came from draining 7%/hour to 2%/hour.

Maybe this can be a solution for many of you to.
[Galaxy S II General] send2toonie:
I'm getting about 8 hours.
[Galaxy S II General] tonynz:
Wow, 8 hours is rubbish.

My newish battery will get about 24 hours with moderate usage, wifi, exchange sync, gmail sync, weather sync, twitter and facebook sync.

Best to get that looked at.
[Galaxy S II General] tameracingdriver:
24 hours is fine, I'm talking about standby time... Ie not using it at all... Mine will drain in less than 6 hours standby when at its worst ; you should be able to get a week or more of standby time.
[Galaxy S II General] send2toonie:
Yeah I know!

Has anyone tried removing any of the samsung apps? Or does anyone know which samsung apps are ok to remove?

I want to try to remove them all using titanium backup and see if that helps.
[Galaxy S II General] ccrows:
I've been reading some of today's ICS comments. It blows my mind that people already want quad-core, when it's currently a struggle with the bugs of a dual-core.

http://phandroid.com/2011/05/10/andy-rubin-confirms-a-new-nexus-is-coming/

*sigh* Hopefully Samsung actually does something about this instead of ignoring it like they did with the GPS bug of the Galaxy S... :(
[Galaxy S II General] ccrows:
I'm guessing you did the factory reset already?... :confused:
[Galaxy S II General] snelz:
unrooted at the moment

had noticed my os was running at 80 percent and battery was draining pretty quickly to for about 3 days, from 100 percent at 9am in the morning was down to 20 percent by 1 - 2 pm. with medium heavy use, just reading xda bit of wordfued, bit of browsing, and messing around with my phone desktop. i did notice tho that only 3 process was showing in the battery usage.

got my gf the same phone and her os was only 10 - 15 percent. but had about 10 procceses in the battery usage.

i turned the phone off when i went to sleep, charged it via usb port from pc, rebooted in the morning.

in manage applications in the running section i stopped accu weather, fring, qik video, social hub x 2, yahoo finance and the wifi sharing + manager, as i dont use those apps, ( although some of those automatically restart)

today by 1pm my battery was on 68 percent, and only 10 - 15 % on the android os, massive improvement, and also that in the battery usage stats i now also had 10 or so processes showing.

hadnt installed or removed any new apps,

just thought i'd share my experiences
[Galaxy S II General] DocRambone:
Todays test, unrooted phone, 6 h battery time with light use. SGS 2 has serious problems...
[Galaxy S II General] pigglett:
Yes it does seem to have dire problems with battery

Was the phone rushed out you think :confused::confused:
[Galaxy S II General] tameracingdriver:
Samsung, rush out a phone? Never! :p

Seriously though, the issue seems to have affected the Galaxy S (1), as well as the Nexus S and Nexus One... so to me it seems like a Gingerbread issue but I'm no expert.

I am using an Incredible S with Froyo at the moment, and on the IS forum they're all complaining they have not had the GB 2.3.3 update yet... well I for one don't want it until I am absolutely sure it won't kill the battery on that - wouldn't be much good for me to have my backup phone have the same problem now would it?! :D

It is intensely frustrating that I have a brand new phone that is sitting back in its box unused though....
[Galaxy S II General] BoostedSR20:
I was using Gingerbread on my captivate, no battery problems. Typical day would be 14-16hrs. Sgs2 setup the same I'm lucky to get 8hrs.
[Galaxy S II General] slyydrr:
For what it's worth, I'm guinea pigging the XEKE1 firmware from samfirmware and my current Android OS usage since about 10AM EST (it's 3PM EST right now, so about 5 hours) is 12%. Before doing this and running XWKDD, it was sitting at about 40-45%. Granted, this could just be a temporary phase and it could pick back up, but so far it seems promising. I'll report back w/ my results/findings tomorrow after I've had 24 hours to run with it.
[Galaxy S II General] Leggenda:
Is there a wifi sharing bug? For now...
[Galaxy S II General] SBS_:
What is your definition of light use?

I had my SGSII going for 12 hours on the battery today with the following use:

-Streaming Sky.fm-radio over 3G with a pretty bad signal for 3 hours

-Had the screen on for 1 hour

-Played with a navigation program with GPS on for 10 mins (probably not a big impact on battery)

-15 minutes of phonecalls

-Twidroyd, Facebook via Pure Messaging Widget, Beautiful Widget, Engadget widget, News Republic and CNN widget syncing/updating every 15 mins

-TV Show favs widget updating

-Gmail on push-notification

-Played some games and surfed the web for the majority of the 1 hour my screen was on, brightness at 100%

-Wifi on for about 2 hours of this time

With this use the battery went from 100% to 15% over the course of those 12 hours afterwhich I put the phone in the charger at around 19:30. Android system is at 20% and Android OS at 16%.

This is with the phone stock and not rooted. Haven't stopped any services etc.

Is this radically different from the battery time you get? I ask because we might have a different definition of light usage :)
[Galaxy S II General] BoostedSR20:
Yeah if I did that I would be lucky to get 6hrs. To me that's heavy use. (Compared to what I'm doing now)
[Galaxy S II General] DocRambone:
Your use is heavy use.... 6 h almost at idle battery 98 -> 10%
[Galaxy S II General] BoostedSR20:
Right now I'm at 2hrs on battery, down to 70%. So far just used it to read some emails, txt a handfull of times and these xda posts. Screen is 50% brightness. Android OS is on top of my battery list @ 52%.
[Galaxy S II General] SBS_:
Weird that there is such a big difference in battery consumption. I think I have 3%/hour if the phone is idling while still having all the syncing/updating going on. Was thinking of rooting the phone to remove some of the Samsung bloat a few days back, but I guess I'll just leave it for now.

Hopefully it's a bug that Samsung can fix for those having issues.
[Galaxy S II General] slyydrr:
I'm not sure. I do know that Wifi sharing in itself seems to take up a chunk of battery life but I'm not sure if that's just the nature of the app, or if it's a bug. Regardless, I have it frozen, along with a number of other apps.

One thing worth noting: When I was running XWKDD, I had the same apps frozen that I do on XEKE1, and the Android OS usage has as of right now dropped 2/3. Unless something crazy happens, it would appear as though the newer firmwares seem to help with Android OS usage.

I'll chime back in tomorrow and Friday to comment on whether these results remain consistent.
[Galaxy S II General] rdy2go:
Xeke1 seems not to have this bug anymore.
[Galaxy S II General] tameracingdriver:
Keep us posted. In fairness, even with the stock original ROM, mine seemed OK for about 3 days before the problems materialised.
[Galaxy S II General] walda:
thats good news.

i think we can wait for a new XWK.. firmware without this problem.

no need to flash the russian one, or?

sent from my SGSII via T*patalk
[Galaxy S II General] rdy2go:
All the locales are available in this multi csc rom.
[Galaxy S II General] airwater9:
Do people understand that this is a percentage - the more your screen is on, the less other processes will consume RELATIVELY. The less the screen is on the more the processes will consume RELATIVELY.
[Galaxy S II General] slyydrr:
Understandable. The only thing I can say from what I've experienced is that I have seen the Android OS consumption issue from day 1 with the original firmware. We'll just have to wait and see :)

Someone else in another thread is testing the XWKDF firmware and from the beginning is seeing promising results, so we'll see!
[Galaxy S II General] slyydrr:
While that makes sense, I think the main thing to point out is that people are practicing their same usage habits on this device, yet the Android OS usage for their usage habits is relatively higher in comparison to prior devices. I know for sure that this is the case for me. On my Nexus One (running 2.3.3), I don't even see Android OS on the list for battery usage yet with XWKDD, it was 45% (and the screen was on for over 4 hours of that time period).
[Galaxy S II General] tameracingdriver:
Indeed - in fact, I checked my Incredible S today and an "Android OS" process does not even seem to exist in my battery usage list!

I tell a lie, its showing 2% now!
[Galaxy S II General] airwater9:
One option is that people contact Samsung technical support either by email or by phone to let them know the issues. Generally getting in their face will prompt them to escalate the issue to their software developers.
[Galaxy S II General] fracmo2000:
I had some serious battery problems when I first got my sgs2, I had formatted my sd card in win7 and wasnt getting a full day out the phone. Yeah, it was new and I was beastin it...but still.

Current Widget would install, but the widget wouldnt update...somebody mentioned power tutor...that works well (no widget however). I then formatted my sd card using android and done a hard reset(4th day)...then the phone was fine. I always charge the phone fully and use it will its about to run out...but I dont know if it was the sdcard, hardrest or just using the battery a few times (not sure if the last option is really feasible?) Also started using Launcher pro (my phone is stock...waiting for a rom)

Im now sitting at 26% after 37 hours...using it a lot for voice, internet and mailing. Really impressed recently, just weird
[Galaxy S II General] BoostedSR20:
Same for my Captivate. Android OS didn't even make it on the list. So same exact setup, same exact usage, and its at 52% right now, higher than my display. On my Captivate NOTHING got higher than my display, ever.
[Galaxy S II General] robstunner:
My Nexus is sitting at 4% android os use with %55 battery remaining and display on at 1hr 15 min. Would freezing the social hub and likewise in titanium backup do anything?
[Galaxy S II General] slyydrr:
Hard to know for sure, but if you're not using it, freezing won't hurt!
[Galaxy S II General] BoostedSR20:
I froze that a couple days ago..
[Galaxy S II General] RogerPodacter:
yeah i am looking at my nexus one right now. Android OS is showing 2%, at the very bottom. the Display is at the top, with 2.5 hours screen on time.

the phone is running on battery for 9 hours and 30 minutes, and just hit 50% battery left.

my point is the usage was rather medium to heavy, yet android OS still shows 2%.

n1 running 2.3.3.
[Galaxy S II General] dwarfhero:
Hi, first post, i've been a lurker a long time now and wanted to add my input.

My phone also had 90% android os at times. Having read around. My battery usage for android os has been around 5% or less. What I did was charge my battery to full, unplus from mains. Turned my phone off. Pulled battery out for about 30 secs, Then turned device back on. Seems for now to have semi fixed this issue. Whether its permanent, im not so sure. Running for a day now since this morning, no issues. Hope it helps if it works for anyone else.
[Galaxy S II General] ccrows:
Never really worked with the GPS issue on the last phone. Devs around here did a much better job...
[Galaxy S II General] BoostedSR20:
Actually pulling the battery is about the only thing I haven't tried... I thought about recalibrating the battery (since I'm rooted) but I can't imagine it would be off from the factory, and that still wouldn't solve the Android OS problem. I'm right at 50% now, and its been on battery for 4.75hrs. Thats with minimal usage.
[Galaxy S II General] sohanlon07:
Mine has about 15% Android usage. Medium to heavy use today with a quick charge to boost in work earlier from the pc, battery finally pooped its clogs about 20 minutes ago. Gonna do a proper run with it tomorrow and see how it lasts.
