For iOS 6, I used an app called BatteryDoctorPro that tracked the power usage and usage time for each app, making it very easy to see which apps used the most energy. Is there such a tweak or app for iOS 7? My wife tend to get something like 4-5 hours of usage at the most out of her iPhone 5, and having done the usual things (Instruments, restore as new, even used it myself for a few days with my own usage pattern), I've come to the conclusion that the reason must be her usage pattern. There simply is no other logical solution. She got tired of me asking her keep track of which apps she used and for how long a long time ago So I need an app or a tweak to do it for her I've tried searching the net, but my search skills might be lacking because I can't find anything... Can anyone help me?
