How long does it take for an ipod nano to charge?

if you want to quick charge it (about 50%-80%) then its around 1-1.5 hours

if you want to fully charge it(100%) then its about 3 hours

HINT: i have seen a lot of people leave their iPod on while listening to music (what i mean by leaving on is the screen is on) and that wastes about 50% of your battery so if you want have longer battery life then try having the screen off
