Battery use
The following topics explain how to care for your phone’s non-removable
battery.
Battery cautions
Storage: Avoid storing or leaving the phone with no charge remaining.
Saved information and settings may become lost or changed, or the battery
may become unusable. Charge once every six months before storing or
leaving unused for a long period of time.
Charge the battery
Follow these instructions to charge your phone’s battery using either the
included AC adapter or via USB connection on your computer.
Charge using the AC adapter
1. Connect one end of the data cable to
the USB port located on the bottom of
your phone.
2. Connect the other end to the
power adapter.
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 adapters
may damage your phone.
• Charging your phone with a USB cable connected to a laptop will take
longer than 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
phone may need a few minutes to build a charge before turning back
on. Playing games or performing other activities while charging may drain
the battery and cause it to power off.
• 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.
