I have an IPhone 4, So when I had updated to iOS 7 my IPhone's battery level was normal it would go to 1% and turn off but now my phone goes to either 69% or 80% and turn off and it would say it's completely dead, and tell me to plug it into a charger. I do that and it starts to turn on and when it turns on it will sometimes say 5% and I will leave it there for 3 minutes and it says 100% ? Or sometimes it will start back at 60% what should I do to stop this problem? Help because my phone won't last a whole day without it turning off
