my ipod touch 5 dies while on the charger still
I just got an iPod touch 5 for Christmas. When it says less than 20% I put it on the charger, no problem. But, even when it's on the charger, it still dies. I have the brightness down and I'm only using one app at the time. All others are closed. I bought another charger to see if the one I got with the iPod was broke, and it STILL did the same thing. Do I need to replace the battery or what? Thanks for any help!!
iPod touch, iOS 8.1.3
