Tips for improving battery performance
Before using your phone, fully charge the battery.
The following functions may drain the battery more quickly:
•Backlighting is frequently on. (To adjust backlighting, select Menu 3 Settings 3 Display 3 Backlighting, then select an option such as 10 seconds or 30 seconds.)
•The phone is frequently used in
analog mode. If 
is not visible on your home screen, you are in analog
mode. (To set your phone to operate in different modes, see “To select digital or analog mode” on page 20).
•You are far away from a base station or cell site when in digital mode.
•Data cables or accessories are connected to the phone.
•Service is not available or is available intermittently. The phone requires
more power to acquire service than to maintain service.
•The earpiece and ringer volume settings are high. To adjust the earpiece volume, see “To adjust the volume” on page 6. To adjust the ringer volume, select Menu 3 Settings
3 Sounds 3 Ringer Volume, and press
left to lower the volume.
•Check how often voicemail notifications, pages, and text messages are received, and how quickly they are acknowledged. To use power most efficiently, acknowledge notifications and messages immediately.
