Your Fire phone is not fully charged when you receive it. Note: For more information, view the Amazon Fire Phone video: Charging and Battery Life.
Your Fire phone comes with a micro-USB cable and power adapter to charge your phone. Using the power adapter, your phone will charge in under five hours. Note: Important: Charge your phone with the USB cable and power adapter that came with your device. Using another power adapter or USB cable, or charging from the USB port on your computer, will increase charging time.
To charge the battery, insert the microUSB end of the charging cable into the microUSB port on the bottom of the device. Note: When your phone is charging, a lightning bolt appears in the battery indicator. If you don't see a lightning bolt, your phone is not charging. To view the battery percentage and charging status, hold your phone at a slight angle to the left or right, or peek, to view the status bar at the top. If you'd like to display the battery percentage and charging status continuously, open the Quick Actions panel, and then tap Settings > Display > Show status bar.
Insert the USB end of the charging cable into the Wall adapter.
Insert the Wall adapter into an outlet to begin charging.
