So, it's been happening for about a week now. The battery does not go down, it stays green the whole time and even when it dies, I turn it back on, and it still shows green, even though it's really only like 5 percent charged. Is there any way to fix this? It's not a huge problem since I am getting a new iPhone 4 this year but I am planning on selling this to one of my friends since it is in fairly good condition. Any help is appreciated, thanks!
