Battery use
The following topics explain how to insert and remove your phone’s battery.
Battery cautions
• Storage: Avoid storing or leaving the battery with no charge remaining.
Saved information and settings may become lost or changed, or the
battery may become unusable. Charge once every six months if storing
or leaving unused for a long period.
• Bulges: Depending on use, bulges may appear near the end of battery
life. This does not affect safety.
• Replacement: The battery is a consumable item. It needs to be replaced
if operating time shortens noticeably.
• Cleaning: Clean soiled terminals between the battery and phone with a
clean, dry cotton swab. Soiled terminals can result in a poor connection
and prevent charging, etc.
14
Insert the battery
Follow these instructions to insert your phone’s battery safely and properly.
1. Remove the battery cover by gently lifting up in the direction shown. There
is a notch located on the bottom left hand corner of the phone to help lift
the back cover up.
2. Insert the battery by aligning the gold contacts of the battery with the con-
tacts in the phone, and gently press the battery down into place.
15
3. Attach the battery cover. Make sure that all the tabs are secure and there
are no gaps around the cover.
Remove the battery
Follow these instructions to remove your phone’s battery. Always power the
phone off before removing the battery.
1. Gently remove the battery cover via the notch at the bottom left corner.
16
2. Remove the battery via the notch under the right bottom edge of the bat-
te r y.
3. Lift upward gently as shown.
Charge the battery
1. Connect one end of the data cable to the USB port. This is located on the
lower left side of your phone.
17
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 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.
