Is there anyway to reduce the amount of battery the Android OS uses? It is currently using 61% of my battery, which is quite a bit much. On my previous phone, the Android OS would only use about 10%. Are there any solutions to fix this? On my other phone I shut off the "Back Up My Data" setting and it solved it, but on this phone, it doesn't help. Any help is much appreciated
Have you tried the fast dormancy disable app in the apps section?
I don't even know what that is Lol Is that pre-installed on the phone?
Look in themes and apps in these forums there's a thread. Install the app disable fast dormancy
Isn't there a way to naturally stop it? I mean, the Androis OS shouldn't be using that much battery. it must be something in the setting, right?

It's a BUG.
This fixes it for most people.
Android OS has always been/will be high on this phone with ICS. It's really old news.

This worked well and lowered my OS from the 70% range to 40%-50% range. Still sucks to have it so high.

my wife's is around 30% and her standby time is obnoxiously good. 48+ hrs between charges
There were some funky reporting bugs in ICS on the SGS2... they didn't really hurt battery life though, there. Are you seeing fairly decent life, or not? Can you, for instance, get 18 hours off charger with 3 hours combined screen on/calls? If so it's probably just reporting errors.
I was seeing high numbers like that on stock ICS on the LGOG, but was also getting zero deep sleep. I just went to JB to fix both that bug and fast dormancy problems... not sure if those 2 were related or not, but got them both gone.

I'm not seeing bad battery life. The phone will go 20-30 hours on the battery. I just know that the OS isn't supposed to be that high on the battery usage, so I was just wondering if maybe I'm not getting the battery life I could be getting. Maybe it is just a reporting bug.
That is a well known reporting error with ICS. Android OS isn't really using that percentage of battery.

Today I woke up and the battery was at 26% after unplugging it at around 11:30 pm. I usually wake up with around 93%. The Android OS had used up 91% of the battery for whatever reason -.- I finally installed that fast dormancy thing. Hopefully it helps.
When the phone has higher than normal OS %, it's because of wakelocks that is preventing your phone from going into Deep Sleep State (CPU). Install Better Battery Stats to see if what is keeping your phone away under Partial wakelocks and/or Kernel wakelocks and also what other alarms might be affecting your phone. You can also use the same app to see how much time your phone is at each CPU State.
Yeah. If your phone is draining by 70% over night that's a bigger problem than just Android OS

When I was on stock 4.1, I was using around 15-20% overnight then I flashed CM stable 10, happily saw the overnight usage drop to 3-6%, then I flashed to CM 10.1 M and now losing 11-16% overnight. Running "deep sleep better battery pro" in slumber mode with little success. Have had issues with that but that's another story. Still in experimentation mode. Starting to use "best battery stats" in hopes of getting more info.

if you install snowjb it already comes with fast dormancy fix. on that rom, android system doesnt use much battery at all. here's a pic to show what i mean.
I think what we are seeing is that kernel wakelocks -- which can be caused by apps -- get lumped in under Android OS.
For example, I was seeing about 9% sns_async_ev or something wakelocks that went away when I froze Smart Wifi Toggler. This made no sense to me but it turns out they were caused by the app accessing the barometer, and turning that feature off virtually made them go away. Overall this was just a small amount of time awake, but all of these add up in that category. It would have been nice to see that under the app itself but there's no way to differentiate that.

I've seen other people post that the OS is using 30%-40% along with the screen using up some power but I'm just curious, is there something wrong with my phone if it says 93% of the battery is being used by the OS and only 3% is being used by cell standby when the screen is off?
Sometimes I forget to charge my phone overnight and I see 25%-35% of the battery gone and the main culprit is always displayed as Android OS using 90%+ of the battery life consumed.
Let me guess..... You're running the official at&t ics release?
Hell no there's no way I'd ever use official builds again after flashing/using custom roms. At this moment I'm using the latest AOKP build along with Siyah Kernel 3.4.3.
Some apps u may use may disguise themselves as android OS. Better Battery Stats could help you determine what's draining it

Alright well I installed the app and let my phone run on it's battery for a couple hours. The app showed that my phone was never in deep sleep.

I'm not really sure what that means but regardless my battery life did improve quite substantially after installing the app so thanks!

lol, BetterBatteryStats shouldn't really be improving your battery life, but who am I to judge. Check to see under Settings > Backup & Restore see if the box for "Backup this phone with my Google account" is checked. That could be causing your drain issue.

Right. BBS does nothing on its own; it merely provides information. Seeing better battery life is a result of the random nature of that wakeup. When I had the issue, I don't think I ended up finding a solution. Unchecking Google backup had no effect, but I leave it unchecked nonetheless.
Well I don't know what happened but obviously something must have if I see 30% increase

Did you recently connect to Kies because I was having probs with my SGS2 getting really hot and losing power as a result of Kies/a dodgy USB lead?
A factory reset solved it however ( remember to back up ) but sometimes just removing your battery for 90 seconds to reset the values works.
Good luck.

Turn off Google backup, face awake, try that for starters
First of all, switch off your phone for a while to see if there is problem in battery or its the apps you are running. If you think it is a stupid step,
Then try using some software like JuiceDefender or something.
In app manager, kill apps that are useless.
Also turn off features like bluetooth, gps etc. if on.
Reduce phone's brightness, recommended to set it to "auto".
Turn off useless vibrations and LED notifications.
You should now see significant improvemance in battery life.
Hope this helps
I have taken all these steps gone ahead to remove live wall paper, auto sync disabled, brightness is set at auto. And its still the same. I don't want to tow the line of hard reset because am not sure that would solve the problem coupled with the time it would take to get my sgs3 to suite me

okay so i thought i had a battery problem before i tried putting my phone aside (meaning no games, no internet browsing and no video streaming nothing, just using whatsapp and leaving facebook connected. I also have lots of apps and games installed over 15 or something)
If you decreasing screen time you will notice a HUGE difference (24hrs in my case), its basically down to usage, I have tried over 10 different roms and kernels as well as the v6 supercharger script, i dont ever notice the difference, EVER. unless of course i use a minimalistic rom with almost nothing to play around with, but if thats how u like it then go for that. Id say following all the fundamental steps will take you a long way
my final advice:
less screen time
when on the screen use the least brightness available
decrease stock brightness even more if you can
less app usage
if your not one to constantly play with your phone and customize stuff on it try installing a minimal rom like
|ROM|XXBLG8| IOIDroid Super Slim Edition | Buttery Smooth | V1.0.0 LIVE !! |
or
[ROM][4.0.4] Slim ICS (SGS3) - Clean, Simple & Fast (63MB)
i dont know if this is a placebo of not, but sometimes i notice improvements when i undervolt, underclock and limit to only dual core. believe it or not sometimes it has little or the adverse effect of saving battery
good luck man

So here is my experience. Have been using android for years, have had an hd2 so I know how to get good battery life results. For some reason I easily lost 15-20% overnight with just the gsm 2g radio on. No matter what I did it drained fast even though deep sleep was fine, all extras sync and etc were off. 3hrs screen on time in 14 hours and it was dead.
I kept waiting for an update to solve this and it never came even though I was force checking it.
I ended up factory resetting the phone and as soon as it booted up an ota update popped up. Since then I am having nearly 6hrs screen on time in 40hrs,which is amazing.

Greetings, I have seen a similar problem back in our hox forums. I have come here in peace to help, though. Recently, someone suggested bump charging, it's like a natural way of making your battery recalibrate itself without wiping battery stats or stuff like that.
First off, charge the battery until it says 100% while the device is on.
Then remove the charger, turn off the power, and charge again.
Remove the charger again when it says full while the device is off.
Turn it on again, then when it's properly booted, charge again, but don't use the device until it says it's fully charged already.
Mind you, we're not sure if it's just a placebo or not. Some claims to have had better battery life after doing this for once a month. I haven't tried it yet, but I thought I could share it here too.

Just to offer two cents from my experience with this phone.
I recently got a replacement for my s3.. the details of that are for another post, but this relates to battery:
when I first got the phone i started using it right away. I did not charge the battery until I got to the office and charged the phone while using it the first day.
when I got the second replacement phone I already had a second battery.
This battery was fully charged and immediately used that in the new phone. fully charged the samsung battery before I used it.
I noticed significantly better performance with the second phone. I think it was because of the way i treated the battery strait out of the box.
any one agree, or have a similar experience?

After the newest update i also notice that it has a high % drain even if i turn 3g off, gps and everything nothing unusual runs in the background that can explain high drain yet it does.. and i didnt notice that before the latest update and i havent installed any weird apps. I also have all my weather and news on manual update so i dont get what can drain the battery with internet off overnight.. its frustrating a bit.
Anyone else experiencing horrible batter drain? Android OS is taking up 50-60% on average and it just eats it up while idle. I'm thinking about a return, this is my second handset, and with a locked bootloader, im losing faith in a quick solution. Any ideas?
Minimal use and quick setup with two to three app dowloads, and my 40% charged new device was down to zero in 2 hours.
I've noticed some battery quirks so far. My percentage drops 3% simply by locking and unlocking my phone within a few minutes. I've also seen it jump up in percentage once so not sure. Maybe there is something in the OS that isn't optimized that's causing the battery drain and quirks? I dunno. Be great to hear from some other people on this issue.

Hi give it a couple of charge cycles it will definitely improve.
Yes, I've got the same problem. The OS takes most of the battery. Idle is fine, but with any use battery drops very fast and gets extremely hot, as well.

Keep in mind that these are new phones with NEW BATTERIES. With that being said, you need to "cycle" (charge to 100% then discharge to 0% <repeat 3-5x's) the battery before we judge and jump into conclusions. Just sayin

For the record, I'm also having pretty lousy battery life. OS taking up 55%+. Last night I charged it to 100%, played with it until it was about 93% and then went to bed. Woke up this morning and it was at 65% with zero deep sleep and 80% OS usage.
Something's funky. I like the phone but can't be dealing with this constantly.
A:
EDIT: Turns out the extreme drain was from the radio. I had switched off LTE in the hidden menu and apparently that causes a ton of wakelocks and prevents deep sleep. As soon as I turned LTE back on, deep sleep came back. So that's somewhat encouraging.
I'll have to look at that. I'm getting a day with light use out of my second phone after a few charges, but it gets a little scary when im using it. I'm staying optimistic, my s3 was just phenomenal with battery life after rom kernel additions.
Can you explain how you turned off/on lte and the menu path?
I dont see an apn option other than the stock one (which im assuming is lte enabled). I'd like to see if it makes a difference. Thanks.
you need to enable network menu in the build.prop and a menu will appear where apn is

This is really disappointing. Physically, this phone is fantastic. It looks great and the specs are terrific but it's crippled by absolutely horrid software which I suspect is the reason for the abysmal battery life.
After my first day with the phone yielded less than 10 hours I decided to do a factory reset and set the phone to Eco Mode. That improved things slightly... I managed to get 14 hours but that was with limited usage. In fact, the only significant difference in results was that, in Eco Mode, Android OS shows that it is consuming 80% of the battery vs 53% the previous day.
There is something seriously wrong with these things... the fact that some people are saying that they aren't seeing the problem has me worried that it may be some sort of hardware-related issue.

I would guess those people that aren't seeing this are not looking at the battery stats, I have never seen Android take up this % of battery on any device and I have been using android since the Hero... about a good 15 devices or more ago I have lost count. Come next Thursday I am going to go switch out for something else if the boot loader is not unlocked yet.

yes i know its a bug but battery life is still good i can use it for 7 hours screen on and still last me a day this lasted me almost 2 days.
i like to keep my gs3 connected to wifi and muted while i'm sleeping but when i wake up i always get 8-10% battery drain (in 8 hours app), i come from a motorola atrix which in the same conditions i get no more than 2% drain over night.
i've tried many roms (omega, foxhound, ultimarom...), many kernels (stock, galaxsih, siyah, phenomenal medium and extreme...), and also some basebands (modem, radio) but i keep sticking with the XXLH1 'cause i get less drain with this one. but in any combination i always get 8-10% battery drain during night.

seems v good for battery life so far. i know your pain though. its non usage time i want to be high batterylife. id expect 2-3 days from the phone when not playing games etc... im hoping this is gonna fix that now. most reports are good about battery so heres hoping.
in a few days will know more
How is it sleeping overnight? check settings > battery and check how much it's awake when the screen is off, then check better battery stats to see what is waking it up, I would probably say you have too much synced.
you're right, i have too much synced, 3 google accounts, plus facebook, twitter, whatsapp, skype and others but those are the same settings i had on my old motorola atrix and even there i got 1-2% drain, although i was on gingerbread.
i will install some battery stats application to see in details whats draining it so much, 'cause under settings it only says that idle and standby time are the draining reasons.
gonna try the leaked 4.1.2 to see if i get better results, thanks!.

Better battery stats is the best, but that is a lot to sync, I would imagine it's not sleeping well because whenever an app decides to sync it will wake the phone up, and let's not forget the S3 has a 1.4GHz quad core CPU, if it wakes and uses all cores it will drain the battery faster than a single or dual core CPU. I notice the Atrix has a 1GHz dual core, so you should expect a lot more drain especially with that much synced, honestly you shouldn't need Skype syncing unless you always want your skype contacts to be up to date in the contacts app, and Twitter just syncs to pull the latest tweets through, you can just do that manually every time you open the app.

does that mean that jelly bean is making you experience worse battery life?.
maybe it's because the atrix has 2 cores but if the gs3 uses all 4 cores to fetch or sync some data, that would mean it's not very well optimized for simple tasks, thanks anyway i'll try better battery stats

Android doesn't fully support multi-core CPUs yet, which is the main problem, all you can try if you need all the apps syncing is download a custom kernel and change the CPU governor this will change how the system uses the CPU and it can help.
Well for starters, Google Now should be disabled if you are concerned about battery life. Also check for and disable latitude and location reported from maps (they are getting activated by google now) Even if data/sync/gps are off google now constantly polling for updates thus draining battery.
With my HD2 running GB/Froyo for over 2 years, and methodical testing to achieve the lowest battery drain in standby (testing for 8hrs at night) the best I could do in AP mode was .35% per hour which is less than 3% over 8hrs.
I have owned and tested my S3 for 4 months and usually get 1% per hr and in AP mode....I get similar to the HD2 above at .35% per hour but I haven't tested to crazily.
I find it hard to believe and would love to be convinced, that any S3 owner can get less than 3% per hour drain without going into AP mode. Please prove me wrong and state your methods for all to learn.
Finally, I do not find the battery drain to be Linear. I am guessing that a battery charged to 100% sometimes may actually be a bit stronger than 100%. So doing a random single test may result in low drain numbers but that may be misleading. That same test performed at 20% level, may yield worse results if in fact my theory that the battery does not drain linearly...is true. But for consistency, I always perform the test at 100% battery and let it sit in the charger for an extra 2hrs before unplugging it. This way, at least the test is more consistent and more directly comparable.
I now have Green Power app installed and it is able to automatically turn off wifi/data in standby under conditions set by me, the user. I am performing some nightly drain tests. I would be thrilled if I could get between .35-.75% per hour. My first 2 nightly tests failed thanks to Slacker Radio....which held a Wakelock even though I bloody killed it!
I think this could be due to fast dormacy
http://www.androidnz.net/2012/06/at-your-own-risk-how-to-disable-fast.html?m=1 there is an app to disable this.
Read this link first though

A bit off topic but just reminds me of my old Nokia N95 because whenever I was in a network dead spot or just have no signal for whatever reason (Gif fgaff) the battery would completely run dry within maybe 6 hours, and you'd think because it has no signal it should last longer than the few days standby I normally got.
And I've never had a SIM in any of my Android phones that lost service for long so has anyone seen this happen on an Android or is it just a Symbian thing?

When a phone has no signal it has to scan all frequencies for a signal, this constant switching of frequencies drains a lot of battery, it also increases the power to the mobile networks chip to try to pick up even a weak signal, which also drains the battery faster, it happens on all phones.

Which I am running but 3% over 11 hours?
Any e-mail accouunts? What do you have enabled/disabled? What is syncing?
The best I have ever managed was about 1%per hour and that was with everything off apart from the cell.

Read the link I posted above about fast dormacy and if this is your problem then get the app fast dormacy from play store
If you're worried about wifi while sleeping also have sync turned off and location in settings and disable notifications from play store and disable notifications from apps also

Will give it a try but I have never seen it show up in BBS in the past hence never tried it (I was aware of it) and as far as I am aware O2 (UK) does support Fast Dormancy.
It is not that I an dubious about the 3% drop over 11 hours I just want to get to the same level!
EDIT: To get the 3% drop do you disable everything you mention above? I use Tasker to disable everything including sync, wifi etc...except the cell. But I do not disable play store notifications seperately.

This is what I have come to expect. 1% per hour is reasonable and typical. 3% over 11hrs...hmmm...I don't believe it.

I have messed with this before without positive results. But anyway, since it seems like you have it working...what is your typical % drain over 8hrs?

I usually turn mine off overnight but if I do want it left on I turn my location settings off and everything that requires wifi and don't lose much.
I'd suggest trying better battery stats from play store then after leaving your phone off overnight dump your results (in settings) and then go here http://forum.xda-developers.com/showthread.php?t=1179809 to ask about your results

After doing a complete wipe install of mean bean, my battery is still draining about 2%/minute. Now, I realize there is more than likely some other issue, that installing mean bean uncovered or removed the block before.
Questions;
1) is it normal for the screen to be using 60% of the battery power?
2) Is there actually an app that controls the battery usage, and truly kills apps?
- I have tested several, with no noticeable difference in power usage.
Thanks for any advice, for a somewhat novice rooter.
yup
The 60 normal if screens been on a lot. The 2% deal sounds whacked. Have u gone into settings/apps/running to see whats running?
Fixed, I think

I'm not sure what I changed, I limited the processes to only 4 running, that might have helped. The battery still drains faster than before when the screen is on, but not as it was before. I am giving "Easy Battery Saver" a try see if that tells me anything useful, it at least keeps the settings that are applied. With any luck it will keep working until I break it again, lol.

I was having bad drain issues and read some post about location tracking with Google maps. I disabled that and my battery life on MB 3.09 is back to normal which is great.
Funny thing is this happened seemly out of no where but I think there was a recent update to maps. My location tracking has always been on and never seemed to affect battery life before. Go figure.
