Re: Application permissions in Android runtime
the only issue I can see with a monitoring app is it will also be running.
Problems with LI batteries are known. If you allow the phone to discharge below about 30 to 25 % the recovery is generally not to 100%. The battery will show 100% but I reality it is not at 100%. It looses ability to fully recharge and eventually will need replacement.
