You can use the phone while the battery is charging, but
doing so will require additional charging time.
Note: You must fully charge the battery before using your phone for the
first time. A discharged battery recharges fully in approximately 200
minutes.
1. With the battery installed, plug the connector of the
travel adapter into the jack on the side of the phone.
2. Plug the adapter into a standard AC wall outlet.
3. When charging is finished, unplug the adapter from the
power outlet and disconnect it from the phone.
