I had my iPod touch on and plugged into a wall charger, I walk away to eat dinner, and when I come back, my iPod is off, and won't turn back on. After about 5 minutes of pressing the power button on and off, it finally turns back on. I unplug it, 10 minutes later I walk away again, come back and it's just turning back on, even though it was fully charged and on when I left it. It's been working fine since then, although all my apps and my Internet are slow. Anyone expierence something similar to this?
