My attain has overheated a few times when charging. So hot that it melted my ZAGG© screan protector! I checked the temp with a temp gun and the battery was a whopping 168°F!!! The screen was a tish cooler @ 154°F and the phone was STILL ON AND CHARGING! now im no expert on battery temps but DAMN, aint that hott?? By the way its happened atleast 4 other times with one or two times getting hotter it seemed but didnt get a temp reading. And yes, my attain still works 110%. Im posting this reply from it now... It overheated like that when i was either sleeping or away from it and it was at a completely idle state. Infact i almost always reboot at night before plugging in to charge while i sleep. Stock samsung charger/cable as well. I kill all background apps or anything running thats not neccessary too. When the overheating happens i check to see if an app re-opened itself and sucked down the cpu/battery but no such luck. I am stumped with this issue and have came to a "troubleshooters deadend". Any thoughts/comments/questions/concerns/backlashes?? :-D
