I found problem.
This is bug or normal on IOS 6.1.2.??? Open your setting->general->usage.. Please see "time since last full charge" see "usage" & "standby". On my iphone this is can't showing time. See pict,,
you could try a hard reset,hold down your on/off button and home button together,let go when you see the apple,the phone will reboot,let us know if it works.

I'm seeing this every now and again on both JB iPhone 5's in our house... one on iOS 6.1 and the other on 6.1.2. About once or twice a week... unplug from a full charge... then look later at usage and it's showing that the iPhone has been plugged in since last full charge. Now, I know it hasn't been plugged in. This has only taken place since the JB.
