    Android developer: What is WakeLock?
    What is WakeLock?

    In order to prolong battery life, over time Android devices will first dim, then turn off the screen,
    before turning off the CPU. WakeLocks are a Power Manager system Service feature, available to your
    applications to control the power state of the host device.
    Wake Locks can be used to keep the CPU running, prevent the screen from dimming, prevent the screen
    from turning off, and prevent the keyboard backlight from turning off.

    Creating and holding Wake Locks can have a dramatic influence on the battery
    drain associated with your application. Its good practice to use Wake Locks only
    when strictly necessary, for as short a time as needed, and to release them as soon
    as possible.

    Since the JB update on ATT S3 last week, I'm having some problems with the media server wakelock.

    Try going Settings - Application Manager, flick across to Running.

    Up the top will be a Show Cached Processes, click on Media, then stop it.

    It will restart again afterwards, but that has cured my battery woes.

    Thanks, Steve. I think I figured out a variation on your suggestion. Battery drain has been less the past couple of hours. We'll see if it holds.
