iPhone 4S gets hot without any reason.
I have a problem with my iPhone 4S. Suddenly three days ago it gets hot without any reason.
After some tests I can tell you that it gets hot when
- the screen is on (even with iphone in airplane mode)
- the iPhone is charging (and screen is off).
Note that the warm side is the motherboard side.
When not charging and screen off , it is OK (cold).
To be sure that it is a hardware problem, I restored the iphone with the latest iOS (from 7.1.2 to 8.3) and the behavior is the same. It doesnt seem to be a software problem.
Have you any idea about this issue ?
Is this a good question?
