Is there an app that outputs the general "use" of the battery?? I kinda wanna monitor the battery and what the ipod touch for. I mean I could use the notes to log when im using the ipod touch, but i believe there is an app which explains how much music you are suppose to get, how much video time, and how much game/intensive/heavy app usage you have. I remember seeing one back when I first had my 3rd gen. Anyone refer me?
