ipod nano 4th gen works only when plugged in
Ive had my ipod nano 4th gen for a while now, more than 5 years, and it hasnt been charged in a long time and i found it and decided to plug it in and charge it and when i do it turns on and shows the screen that its charging, the only problem is that the only way i can use it is if its plugged in, and as soon as its unplugged it dies. how can i fix this?
iPod nano, iOS 1.x, owned for over 5 years
