Default [Q] GPE 4.4.4 Offline Charging behavior

HI,
I've flashed the last 4.4.4 GPE update, but when I turn off my phone to charge it off, the phone shows the icon, and then the icon start to charge, but after that, íthe screen does not turn off completely! The screen goes all black! If i press the button the battery icon shows again. but again... íThe screen does not turn off completely!

I want to know if this behavior is normal
Who else have this behavior
If you don't have this behavior, how it should be
