My iphone 5 is really hot and i will be very fast empty ?! What can i do and whats Happend?
The iPhone is probably hot because the battery is draining, are you watching videos or playing a game when this happens?
Take a look at this Apple webpage for tips on improving battery life -> Apple - Batteries - iPhone
If the iPhone got too hot, it would shut itself off and show a disabled message.
Take a look at this Apple doc -> Phone, iPad, and iPod touch (4th generation): Keeping device within acceptable operating temperatures
