How long does it take to fully recharge a battery?
iPod fast charges the battery to 80 percent of capacity in an hour. However, it can take 4 hours to fully recharge a battery. Even in sleep, iPod uses a small amount of current, and the battery slowly empties. Stored at optimal storage temperature, the battery will empty in 14 to 28 days. If you want to get the most out of your battery’s life, make sure that you do not charge iPod while it is in a carrying case or cover. Also, you should charge iPod when it has fully discharged even if it won’t be used right away.
