Very basic

Just a page of basic information telling you how much is left in your battery and how long you can use various applications for (audio, video, web surfing etc.) there's nothing else. If I wanted to upgrade to remove the adds there's no way of doing it. There are three icons at the top of the screen but touching any of them just takes you to a page where you're asked to buy a slot machine game.

Worst battery app EVER!

This is the least helpful of no fewer than 20-30 battery app's. You can't even receive the basic battery saving tips that almost every other battery app offers unless you download a slot machine gaming app first, for that matter you can't get a single fact before the download and I kept looking what I must of been missing after the download because it was such a nothing tool/no help for a download that makes them money. Worst battery app every. Try Battery Doctor HD. IT actually has a diverse set of tools that are amazing, and free too... Don't waste you space, time, or encourage such bad applications to come into reality
