IPhone 5 keeps restarting / glitchy screen?

This phone is a year old. It's worked great and never had any problems with it. It's been jail broken for 3 months. It's running on 7.0.4 and I haven't updated it due to the jailbreak. Anyway last night the battery died. And when I turned it on today it's been restarting every two or 5 minutes. The screen is flickering on the sides and if I shake the phone it shuts off. It feels like something is loose. It's sounded like this for 4 months now though and has been working fine however when i shake the phone something is shaking around. It might be the battery as we'll cause when it's plugged in the percentage never goes up to indicate that it's charging. I will try a factory reset because nothing else is working. But what could this be?
