The battery that comes with your phone can be charged
whenever you wish without affecting its performance. You
can also charge the battery when the phone is off.

pressing any of the volume keys in standby mode. You can
move downwards in the menu by pressing d. The
remaining standby and talk times depend on the type of bat-
