IPhone 4 Overheating
My Iphone 4 has recently started overheating and draining the battery at 20X speed than normal. I was on iOS6.1.1 and just updated to iOS6.1.3. I am still experiencing the same issue, my phone is out of apple 1 year warranty. I am not sure what to do at this point as it is difficult to make phone calls with a phone that literally burns your ear. Please provide a possible solution/suggestion ASAP. I am looking forward to hearing from Apple experts.
iPhone 4, iOS 6.1.3
