i think people honestly worry too much about the temps. the temp you see on set cpu and all battery widgets is the battery temp,not processor temp.none of the cpu temp widgets will work on the rezound,as it does not have a cpu temp sensor. if youre having the issue thru 4 phones,have you used the same battery? maybe its actually a battery issue,not a hardware issue. at any rate,the battery is rated to 140*. as long as you have insurance,just let it be hot. might not ever be an issue. you could try some different batteries if you want,and see if that has any affects.
