Why does my Nokia 1520 randomly reboot until plugged in?

Nokia 1520 randomly reboots until plugged in

I was having some issues with my SD CARD (it had to be scanned for errors constantly) so I eventually took it out. About the same time the Phone started to randomly reboot itself over and over until I plugged it in. To be more clear it got stuck in a reboot cycle where it would start to boot and then shut off and then start to boot and then shut off. The only thing I could do to stop it would be to plug it in.

Steps taken:
Took out SD Card
Factory reset

Carrier: AT&T
Windows Phone 8.1 update

When the battery is full or plugged in I can't reproduce the issue, but when it's lower then 60% or so, I can repro the issue by changing between apps or selecting airplane mode and then switching the wifi on. Basic multitasking appears to set it off.

Please help! Has anyone has this issue? If it is an issue with the battery has anyone ever bought a new one? How much did it cost you? I heard we have to take it in to the AT&T store.

Thanks!

You need a new battery. Take it to a care center or Microsoft store if your under warranty. If not its a $50 fix.

I took it in to the AT&T store and they gave me a new one after determining that the phone itself was defective.
