    A great idea for an app! - Battery juice is always running out too fast!

    Access your home PC from your Android device by using the 2X client App from
    also has client for iOS. Voted 20th overall best Android App!

    This is truly a great app.

    But I have a very different solution to my battery drain issue: since I like to have a number of apps going simultaneously, I always carry around a fully charged spare battery which takes no longer than a minuite to install (including restart). That way I needn't concern myself with either battery drain or apps which prevent it.
