    Hello all, i'm having the problem where the Android OS is almost at 60%. I'm just wondering did you guys use any kind of app to keep it down?. I'm really confused with the processes that's running, I mean stopped it and few minutes after that it'll be back on. I'm sorry it sound trivial but I'm fairly new to Android OS or for that matter smart phones. Any help is much appreciated, thanks!!

    Yeah graffix has a point here, I'm not sure how valid any of these concerns really are. What we would need are absolute numbers for OS usage which don't really exist AFAIK. Because the task manager shows the OS usage as a percent everything has to add up to 100%. So your OS% may be high, but it just as well may be because you have nothing else running as opposed to there being an actual problem. With nothing else running something has to make up the majority of the 100%, which would most likely be the OS.

    Anyone get to the bottom of this? I'm stock. Tonight I'm at 11h 55m with 54% remaining. good for the stock battery, Is there anything to be concerned about. Am I getting less battery life than I should? Should I exchange my phone? I'm a bit of a novice with this so excuse the dumb questions. Could it have something to do with the display? Those that have high display numbers are you using live wallpapers?
    Nothing wrong with your phone.. your at 50%+ of battery life after 12 hours that great...

    This makes sense because i would be sleeping and when i wake up the next day my os % is high but when the phone is in use during the day it drops ... So if it adds everything to 100 and nothing but the OS is running as low as it my be the % will still be crazy high due to everything else not running...

    so after over 4.5 hours of not really using the phone for more than a minute or two i am still at 97%. my os is at 80 or so. and i have been roaming for most of this time. i think the big thing is also when you are not on wifi to shut it off. i havent found a setting other than in battery saver mode that will shut it off when not in use. but 3% loss after that long is amazing.

    I have also noticed that if i am using the phone constantly and not shutting the screen off the OS stays at about 15% or so. As soon as i shut the screen off and let it sit for a little the OS skyrockets up to 50% or so.

    I think its a combination of the WIFI and the suspend mode.

    This has been my observation as well. If I don't use my phone much, and my screen if off for a long period of time, Android OS always shows at the highest %. As soon as I use my phone for a reasonable period of time, Display jumps to the top as the highest % by far and Android OS drops to high single digit or low double digit percentages.

    When I first got the phone on the 16th, the battery life was amazing. Over the last couple of days it has been awful. Today it was really bad so I un installed a bunch of apps, and restarted the phone. It jumped down from 50ish% to below 10%. Does this make sense?

    all depends on what you are doing. I can get about 30 hours constantly with minimum use. Today was the day i was able to test it out as i would use it normally at work. about 50 text 30 mins thru out the day browsing the web and checking my feeds FB,G+ ect... used GPS and G-music for about 20 mins together and just G-music for 20 mins coming home. about 5 3 min calls... tried to play third blade a few times but would close after a minute or so. unplugged at 6am and got home at 5pm still had around 35% left just plugged it in with 28% left. For what i need it to do and my usage the battery rocks. My Epic would have needed the charger by 1pm at 15% or so...

    I do check task manager a few times a day and clear the cache.

    Guys, if you aren't using the phone that much of course the OS is going to use up the highest percent of the battery... because you're not using anything else!! Try making a few long phone calls or playing some games and see how low your OS % is and how high the other %s are.

    My Evo 3D sits on my desk with all radios on and I havent touched it in about 15 hours and the OS is at 4% and never goes above 10% ever really.

    This is a software bug in the phone. Whether its a bad batch of phones we dont know yet.

    The last thing to talk about with respect to battery life is the infamous “AOS Bug,” where AOS references the Android OS line item in the battery use window. I’ve read just about everything there is I could find on this bug, and believe it to just be related to how Android reports this metric based on CPU time that a process and its children use. Some have speculated this is something which has showed up with dual core SoCs. To be completely honest, I don’t put much stock in the line-item breakdown of battery use to begin with, what I look at is the graph view. Either way, the battery numbers above speak for themselves, and SGS2 battery life is definitely superior to the predecessor, AOS issue or not.
    It isn't a Sprint thing or just limited to the Epic Touch.

    I switched my roaming to Sprint only this morning, and the difference has been huge.

    Great tip.

    I added it to the 30+ Hours Battery Life on the Epic 4G Touch-How Long Can You Go?

    → Try Roaming off: Tap Home > Menu > Wireless and network > Roaming > Roaming mode > Sprint only.

    Yes, just wanted to comment that my battery life went from aboit 10 to 12 hours to 28 to 32 by switching roaming settings. The problem even occurred at my work, where I have full signal. These battery times are similar to my epic 4G in the same environment. My guess is some bug similar to the signal search bug on the original epic where you had to toggle airplane mode to fix it.

    Haha on another note, at home with wifi and poor signal im at about 2 hours off charge and 99% battery still, just turning off roaming... Hopefully they fix this, cause this is a bit ridiculous.

    I just took my epic touch in to the sprint store and told them about the issue (50-75% Android OS usage) i've been having they did a diagnostic on it and the phone failed the signal portion of the diagnostic so they gave me a new device hopefully this one wont have the same issues as the last one.

    I did that all day yesterday and still had the issue. I didn't think that would be the issue tho since I was on wifi most all all day.

    Eveyone must understand we have a radio for voice and a radio for data. So being on wifi covers data then what...

    I really dont think the android os being 50 - 70% is a problem. Mine is 53% now with good battery life. Its either going to be android os or display in most scenarios taking up the majority or the battery... It was high when I had roaming on and it was killing my battery and high when my battery is doing well.
