Some common problems with the iPod Nano include its inability to power up properly, its battery draining too fast, and its display becoming unresponsive and not being able to recognize input once the Apple logo appears on the screen. Other problems include issues regarding content synchronization between an iPod Nano and a computer and headphones not producing any sound during audio playback.
If your iPod Nano fails to power on, connect the device to a power source using the charging cable, and wait at least 10 minutes before disconnecting it. If this fails, reset the device by holding the Sleep and Home buttons for six seconds until the Apple logo shows up on the screen. After this, connect the iPod Nano to your computer, start iTunes, and check whether it recognizes the device and whether it’s able to play music from it.
Resetting the device also resolves issues regarding unresponsiveness, whereas removing the protective sheet and cleaning the screen with a microfiber cloth typically handles input-related problems. If an iPod Nano app becomes unresponsive, reset the device, or restore it to the default state by syncing the iPod Nano with iTunes and using the Restore option. For connectivity issues, clean the connectors on the Lightning cable, and connect the device to a USB 2.0 or USB 3.0 port on your computer without using a USB hub. If this fails, restart your computer, or restore the iPod Nano software.
