I have had my TP almost two months now. I have never had issue with heating or charging. I make sure I have no prorams running and screen turns off after 1 min. Last night battery was at 21% when plugged into charger and no programs on. After being up for 30 minutes I heard the phone reset, I saw the phone try to boot up but went black. The back was hot so I took out the battery to cool off not so hot it burns your hand. Put back in and phone would not start so plugged back in and phone wheel showing charge state so I pushed power and came bach on the radio turned off.
I am stock rom with radio 1.11f, battery hack, White flip clock, sensitivity hach on screen. I do not thing programs matter since they were off. Any idea from the peanut gallery?
