Iphone 4 battery drains too fast due to plugging and unplugging alot?

My iphone is still in awesome condition! Sometimes the screen would get really hot when i'm charging it and i don't even know why. And because of accidents or just my idiot friends ( just playing) my phone gets plugged and unplugged a lot.sometimes its not because of accidents, but because of the wall plug that makes it unplug and plug so rapidly… And now if i use my iphone my battery drains pretty fast.can't even last a whole day even if i barely use it. Any help please? I wanna keep this phone in good condition until i get a new iphone 5. Even with the new phone i need to be careful.

I would recommend you to check out the site for problems. I have read some useful tips from there and restored my iPhone when it got dropped in water:-)

There are more than a few suggestions on caring for and extending the life of the battery in your Apple iPhone.

  • New iphone battery still drains super fast? I have an iphone 4, as of last weekend the battery life drained like 2% every two to three minutes. I bought a new battery since then but it's doing the same thing. I was wondering if it was the screen that effecting it because it is badly broken. Parts a chipped off, or maybe something inside the phone that's causing it
