3. Connect the power adapter to an electrical outlet to fully charge your
phone.
• Use the power adapter that comes with your phone; using other adapt-
ers may damage your phone.
• Charging your phone through a USB cable that is attached to a laptop
takes more time than charging it with the power adapter.
• The phone will power off automatically when the battery is too low.
Charge the battery if this happens. When the battery is critically low, the
charging status may not be displayed immediately (i.e. you must wait
before it is displayed). Using the phone to play games or perform other
activities during the charging process may cause the phone to power
off due to low battery.
• The battery will gradually discharge if it is left unused for a long period
of time. Before using the battery again, you must recharge it in order to
power on and use your phone normally.
