Answer to: iPhone 5 front glass panel separating/lifting away from body?Apple will replace the iPhone! I had exactly the same problem this week with my iPhone 5, which is nearly 3 years old. It is out of contract. It got very hot during charging while I was using it. I guess it's been doing this for awhile, but I had not noticed it before. Then I noticed the upper left corner edge had lifted by a small amount. It seemed to get worse after another charge. I don't use an external case. After checking websites, a faulty battery seemed likely. I took it to an Apple Store. They agreed, and a diagnostic test showed the battery was out of the green area. Result: I received an instant replacement with a brand new iPhone 5! Guess upgrade will have to wait a bit.
