Battery life appears short
Learn how to conserve battery life.
- Ensure that the latest software is installed on the iPod.
- When charging, use the cable that came with iPod nano (7th generation) and leave the device connected until it is fully charged.
Note: If you are charging using your computer, don't connect iPod nano (7th generation) to your keyboard. Also, the computer must be turned on and not in sleep or standby mode.

When you are done using the iPod nano, verify that:
- The Radio application is off (tap the button)
- Music is paused (tap the button in the iPod application or disconnect the earphones)
- There is no active Pedometer session (tap the Stop button in the Fitness application)

Best Regards.
