Is there an app that shows what is causing the battery to drain? This morning for example, my phone was completely charged, freshly rebooted, and I was just texting with a friend of mine, on and off. The phone is now 46%! There isn't anything running in the background. I am not asking for advice what to turn off service-wise, I like to know what are good apps that gives me detailed data on the battery itself. Power cycles/battery health/which process is draining it more. I don't need or care to know that I can have 3 hours of standby time left/2 hours of movies left/etc. Is there any such app? App store preferred since there isn't Cydia yet for iOS 7 on iPhone 5. Thanks.
