IPhone Firmware Trouble Any Help?

Did you Jailbreak it?

Ouch, that shouldn’t be happening. You could simply try letting the battery drain, waiting a couple hours, and then fully recharging it. Apple reffers to this as callibrating the battery. Most likely though, you should just go ahead and do a system restore after you sync it with your computer to make sure everything is backed up. That’s all I can think of but good luck getting it to work properly.
