Why does my iPhone keep overheating?

My iphone 4 keeps saying that it needs to cool down yet its not even hot.It'll work for about 5 minutes then go back to the temparure screen. Turning it off and on helps but only for about 5 minutes.

It is 90 degrees outside today (at least where I'm) and using it would heat it up even if you can't feel it. I suggest turning up the air conditioner or using it someplace with a lower room temperature.

  • Why is my iPhone 5 overheating? It's also killing my battery. I've barely used my phone today. I charged it overnight and started using it at 7 and its now 12:20 and I only have 14% plush phone is super hot. Why is it doing this?
  • Why is my iPhone 4 overheating? It always says iPhone to hot get out of sun and shuts down, where I live it's 45F and cloudy, WTF!
  • Why does my apple iPhone charger keep overheating? Whenever I plug my phone in, I worry about whether it's going to die because I plug it in around 5% and a lot of the time my charger will overheat and stop charging even though its plugged in. So I'd have to unplug it for a bit and wait for it to cool down while my phone is dying. When I touch the charger it's always super warm. How do I fix this? Or is it just broken?
  • Overheating iPhone 5 after throwing it? I was very stressed out this morning (my roommate was defacing my property as a "joke") and in a moment of anger, I tried to throw my iPhone against my pillow, but I missed and hit the wall. Now it is overheating, losing battery life, and it is continually searching for a cellular signal. Any ideas how to fix it, or do I need to buy a new phone? *By the way, I know throwing the phone was stupid and wrong. I just need to find a solution to the problem at hand.
