Battery capacity
When the battery becomes low, a warning window is displayed and the unit automatically turns off the LCD. When there are approximately two minutes of talk time left, the phone sounds an audible alert every 30 seconds and then powers down.
Note: Long backlight settings, searching for service, vibrate mode and browser use affect the battery’s talk and standby times.
There is also an internal backup battery that saves all settings in the phone if the regular battery is discharged. An internal backup battery needs an initial charge of 24 hours.
The internal battery maintains data for about four hours. Perform ActiveSync operations or a backup utility frequently to avoid loosing any information in case the battery is fully discharged.
