S2 Battery Drain Problem - solved for nowSupport

    Hi,

    I finally discovered that it was the Launcherpro that was causing the battery drain in my S2 resulting in the Android OS to be using high level of CPU.

    Using android system info app, I can see there are 2 processes ( android.process.acore) using up to 100% of CPU regularly. The exact file is com.fede.launcher running in the background.

    So, this is what I did:

    1. Go to Launcherpro General settings = disable the Keep in memory
    2. Enter Android system info app again, manually end the task for android.process.acore
    3. This would stop the android os drain

    Please note that, whenever you restart your phone, the same file will reappear and you need to manually kill it. This solution works for me and I'm now able to use S2 for 2.5 days with moderate use of 3G and screen brightness at max.

    I guess this is my best solution until Launcherpro comes up with an update that solve this problem. At least I know it's not Samsung's fault.

    I was using Go Launcher today and had my worst battery life ever, 30% by the, usually in am at 70%+ at that point of the day.
    Killed Go launcher and went back to the. Charge seems to be holding better now.

    Hey,
    I downloaded the Android System Info (ASI) from Android Market.
    Then i opened this app and went to the tab "Tasks".
    There I could see the task -- android.process.acore
    I clicked on the small plus (+) sign next to its name. It showed the option "End Task". I clicked it. The task vanished from the list.
    Then I came out and did some surfing in folders. After 5 min, I checked the "Tasks" in ASI, acore process was there again !!!!!

    How come you prevented it from starting again. If it is starting again then I think it is a system-required task that will start again when u kill it.

    You have to be rooted and install some app for freezing other apps like TitaniumBackup. U can freeze there whatever process or app u want.

    LauncerPro hasn't been updated in a LONG time. I wouldn't recommend using it on a GS 2. It will kill your battery in just a few hours.
