Mine is a a neglected phone. I spend very little time playing with it and as a result it's almost always just sitting waiting for a call. What I've noticed is that the maps app is one of my top battery hogs and I'm wondering why. This screen shot below shows a good example. I finished charging the phone to 100%, locked the screen and did absolutely nothing with it till capturing this image. The maps app was not even running, so what is it doing that it accounts for 13% of the battery usage?
