Hey there,so i have an HTC One M8,anyways i have it sent it to repair not in the warranty tho,it came back with the bottom speaker having high distortion,i replaced it,still same thing,thought it was some problem the the two pin connecter,still same,after a day the main motherboard was getting super hot,and eating the battery,i turned if off "the phone is still warm" and after ine hour,no more battery,i concluded that the motherboard DRAINS from the battery even when the phone is off,bought a new battery,this time left the phone open so i can see whats going on,it still eats from the battery until it kills it,and the motherboard stops getting warm until i can confirm the battery is dead,im trying to identify is this a short circuit ? And how can i fix it ?

Thanks.
