Iphone gets very hot when charging and battery dies fast?

I took it to Apple and the associate told me that the battery is fine and said I needed to restore my phone back to factory settings. I did restore it and of course, it did not work. That wasn't very helpful. It's still getting hot when I charge it and as soon as I take it off the charger it loses battery very fast. Within an hour I'm back at 2% battery life. Does anyone know what else the problem could be?

You should get a replacement iPhone. If urs is under warranty, you get a free new one.

  • Why do I do this? I'm very very very tired yet I don't want to sleep? I want to sleep because I'm practically blinking and bobbing my head side to side like a drunken man but I just don't want to sleep. I watch tv or go on Facebook or play on my iPhone. And I'm starting to get dark circles. And as a guy I don't wear. Concealer or whatever
  • My iPhone 5 gets very hot in my otterbox defender case? Is it just me or does every-time i put my iPhone 5 into a otter box, it gets really hot. All my other cases don't do this but this one it does. Is it just me?
  • My iPhone 4 won't charge and gets very hot? I've had my iPhone 4 for about 2 years, but recently since I went abroad its been having troubles. It won't charge longer than about 40%, but then it looses charge really quickly. It also heats up allot on the back of the phone, and the torch used to be constantly on dimly but that's stopped now. What is the problem and how is it fixed? , thank you
  • IPhone gets hot while charging? Went to grab my iPhone to see if it was through charging and the sides literally singed my fingers. Right nows palm is throbbing because I'm holding it. It should not have to be like this. Should I stop charging it?
