This is an app that should be the first on your device. This is a great app that will show you when you need to charge, how long to charge, and even keeps a log of your charges along with the dates they were recorded. Unlike other battery management apps this one lets you take full control and customize it by changing the themes of it. This great app also offers battery tips, health bar, full help guide that will take you step by step throughout the app along with information on contacting the seller. It has a great settings feature that has a reminder to charge, you can lock your theme, change the sound your alarm makes, trickle charge time, and a status list.
I got this app and followed the guide and I have seen a BIG improvement on my ipod touch battery life. This app will also run in sleep mode keeping up with your charge time. Gamelingo also has a Battery Lite version and a FREE version but I would suggest getting the full version. Overall this is a MUST have app, it is well worth the dollar.
