Understanding Battery States
When iPod nano isn’t connected to a power source, a battery icon in the top-right
corner of the iPod nano screen shows approximately how much charge is left.
If iPod nano is connected to a power source, the battery icon changes to show that the
battery is charging or fully charged.
You can disconnect and use iPod nano before it’s fully charged.
Note: Rechargeable batteries have a limited number of charge cycles and might
eventually need to be replaced. Battery life and number of charge cycles vary by use
and settings. For information, go to www.apple.com/batteries.
