Good, but not the best.

This app is grey, if you are only looking for how charged ur battery is (ONLY)

About Battery, Is a much better app. It hows exactly what percent your battery is every 5 seconds, and also calculates how much video/music/stand by time you have, and its completely free!! It also shows you other features as well. So I suggest you get about battery before it is a paid app.
