    Exclamation How To Fix ICS Battery Drain Bug

    Guys, this issue seems to be caused by the "Auto-Rotate screen" setting being enabled under the Display settings.

    Some proof of this is by viewing CPU usage using OS Monitor. With "Auto-Rotate screen" enabled and the phone idle, CPU usage of "Android System" will remain anywhere between 25% to 30% (while the phone is idle) and apparently prevents the Nexus S from going into a deep sleep, which of course will be draining the battery faster. By disabling "Auto-Rotate screen", the CPU usage of "Android System" drops to between 0% and 4%. Re-enabling "Auto-Rotate screen" caused "Android System" to consistently jump between 25% and 30%. So I keep "Auto-Rotate screen" disabled now. Try this out as I had the same issue and my battery now lasts longer with it disabled. Download "OS Monitor" and see for yourselves. It MUST be a bug that is hopefully fixed in 4.1.1.

    I hope this works for you! Please let me know

    Cheers!

    Thats weird on my nexus the cpu sits around 2% when just running os monitor. Disabling auto-rotate didn't really change it. Maybe you have another process sucking the cpu?

    Do you have the Galaxy Nexus or the Nexus S?

    I am running 4.0.4 on Nexus S.

    It's tough trying to identify the battery drain issue as so many people seem to be experiencing it...

    And it is definitely 100% the "Android System" process consistently running between 25% to 30% even when idle, but ONLY when "Auto-Rotate screen" is enabled. With it disabled, it goes straight down to between 0% and 4%.

    I've got a Photon Q. I noticed my battery goes 92% to my screen. I tried your trick. I'll report back if it works!

    People say the ram is there to be used but this will surely use more battery. I find uccw will sometimes be a hogger so dont know why some apps seem to randomly have been using battery in standby or how accurate a stock battery monitor is .Anyway, i have same problem as After ICS update with phone taking 55 seconds to shutdown. This cant be good - what is running that cant stop on shutdown?
    I think cache cleaner messed things up some how.

    I have heard of others complaining about battery drain with ICS, others that have the same hardware I do (Samsung Galaxy Tab 8.9). I find that the app I am running has more effect on battery usage than any sort of system housekeeping. After nearly 12 hours since I last charged my device, I still have 87% of the battery capacity. The screen has been the heavy user with 64% usage.

    When I play a graphic intensive game like Bubble Shoot, I'll see my battery power go fairly quickly but that is more a factor of my playing the game for an extended period of time, I find it very addictive.

    I tried OS Monitor on my SG3 with screen rotate on/off and it does not change my CPU usage which sits around 3% for Android system.

    My Android system sits around 3-5% with auto-rotate screen enabled (Galaxy S2 Skyrocket).
