Tips for improving battery performance
Before using your phone, fully charge the battery.
The following functions drain the battery more quickly, and adversely affect
talk and standby times:
• Backlighting is frequently on. (To adjust backlighting, see page 63.)
• The phone is frequently used in analog mode. If is not visible on the
home screen, the phone is in analog mode. (To set your phone to operate
in different modes, see “Roam Option” on page 73).
• You are far away from a base station or cell site when in digital mode.
• Data cables or accessories, such as the Hands-free headset, are connected
to the phone.
• No service is available, or service is available intermittently. The phone
requires more power to acquire service than to maintain consistent
service.
