My opinion
We understand about iPhone safety standard that use IEC 60950-1 UL 60950-1 in the United States, CSA 60950-01 in Canada, EN60950-1 in Europe and more.

Hot and stops automatically. If viewing angle is also good to stop working before the injured from the battery. But must be other ways to solve problems and investigate. For example, a number of problems with how Represents? The number of times often?

And the rate of problem Acceptable?

I think the problem of high heat will not be caused by the use of movie music video viewing online play. But from experience with the phone device GPS. Phone is very hot when used in conjunction with GPS. Maybe the problem may be caused by this section.
