Is there any Android Apps that i can get from the market to help deal with the battery life and data useage. I kept my phone on over night to see how much battery or data it uses. And it turns out that in an 8 hour 30 min period the battery drains about 10 percent and uses about 2.5 data. Is there anyway to get an app to deal with this. Such as close apps and make the phone use the battery more efficiently.
