hold charge as it did when it was new. When the battery life becomes 
noticeably shorter than usual after being charged properly, replace the 
battery with a new one of the same type.

temperature and the age of the battery.

message. When the battery power is almost exhausted, your phone will 
power off automatically.

connect, and how you use your mobile phone.
Try the following to conserve battery power:
•  When you do not need 3G services, set your phone to connect to a 2G 
network.
•  When your mobile phone is not in use, turn off the screen backlight.
•  Reduce the time it takes for your screen backlight to turn off when your 
phone is idle.
•  Lower the screen brightness.

visible to other Bluetooth devices when you need to establish a Bluetooth
