Amazon's help and customer service features online Amazon device support. The support includes Kindle troubleshooting for Fire TV, Fire phone, Echo, Kindle Fire, Kindle e-readers, and Kindle reading applications.
The Amazon Kindle troubleshooting suggests restarting a Kindle to attempt to solve most issues including frozen screens or trouble with downloading. For more advanced problems such as issues with syncing, connecting to Wi-Fi, or maintaining battery charge there are individual troubleshooting pages.
If a Kindle device has difficulty maintaining a battery charge, Amazon suggests conserving battery by either turning the device to sleep mode or turning off the wireless Internet when the Kindle is not in use. If the troubleshooting guide is not useful, it is possible to contact Amazon for further help.
