IPhone 6 left out in sun I left my iphone 6 in the sun and it stopped working.  It has been a few hours since I cooled it down and it still doesn't work or even take a charge.  Is the battery damaged?  How do I fix this problem?
Let the phone cool down for a couple of hours (place it by a fan), then plug it into your Mac and hold down the iPhone's power button and home button together for 20 seconds for hard reset.

You could try the hard reset first, if you choose.
