My battery life (iPhone 5) (iOS7)?

So, i don't know why but my standby time and usage time are the same and that just doesn't make any sense it's just impossible. I don't know how to fix that. Please help me! I've already tried killing my apps running in the background, rebooting even resetting my iPhone and setting it up as a new phone!

Deleted and download the app, it will reduce the chances of crashing/errors.
