I have an iPod Touch, 3rd generation, and I've had it for about 2-3 years. Just last year, it went completely dead. But last night overnight, I charged it and when I turned it on, it said it had 20% battery. I tried it again for a couple more hours and it said the same thing, 20% battery. Not fully charged. I had tried using a wall charger, a laptop, and many other chargers to try and fix this problem but it's always 20%. This has to be a battery problem and not an iPod problem, right? I've already taken it into a store but they gave it back to me, unfixed.
