Iphone stuck on charging screen?

My Iphone 4s has been stuck on the red zone charging screen for about an hour. It died pretty fast today and didn't charge completely last night for some reason, It was working perfect this weekend. I even restored it from iTunes and I'm right back where I started and I'm not sure what to do. Is the battery dead completely? I've tried the wall socket and my computer.

Hey you need to change your USb charger because thats the problem.
