My phone discharges overnight if I forget to disable my "map my walk" app. Perhaps you have some app that is using up your battery.
I have found this out as well. Not necessarily with this app but I have some apps that use the location services and they do not always stop this function after you close the app. On my older iphone you can tell is location services is active if you have the little triangle/compass pointer icon active in the phone. If it is it will constantly be looking for and updating your location.
FYI, gasbuddy is one that does not always unhook location services when closed.
