Q: Tips on charging the iPod battery
When do you usually charge your iPod? Is it whenever you see the red light or do you still wait until your iPod is fully drained? Is it OK to leave it plugged over night? Or is it better to unplug it as soon as the light goes green? What do you think?

It's perfectly fine to use your device while it's charging.
Yes, it's perfectly find to leave it plugged in overnight.
