On the 3rd day, my battery became FIRE HOT and LOST CHARGE QUICKLY

Question

First, I LOVE my iPhone 4, it's amazing, but I did want to at least share what happened to me this week. My iPhone 4 battery started going from 100% charge to 40% in 90-minutes - It was only in standby mode. The phone became VERY HOT, especially around the steel edges. I called Apple Care and they said "Do not use the phone because it could be hazardous" and advised I go to an Apple store. I did, and they exchanged it after verifying it wasn't safe. Apple has the best customer care on Earth. While I was there, someone else was there exchanging their phone for the same reason - They have a secret stash in the back packaged in unmarked small black boxes, just for this reason. Anyway, the phone rep at Apple confirmed to me that there is a battery issue with the new phones. They guy at the Apple store who helped me said he has seen few issues for signal or the yellow screen, but a lot of hot batteries that do not hold a charge.

Answer 1

That's really interesting, my iPhones battery is horrendous, I've just finished reassuring it, powering it back up to see whether I can improve the situation (looses 26% charge in standby at night when I slept for 7 hours. My first comment to my friend was, the iPhone 4 was amazing, but was very warm. Will be interesting to see if my problems over with this reset, or if I too have a battery problem. Thanks for sharing.
