2.2.4 Important Information About the Battery

• If the battery has not been used for a long period of time, you may not be able to
power on your mobile phone immediately after you begin charging the battery.
Allow the battery to charge for a few minutes with the phone powered off before
attempting to power on the phone.
• The battery will not hold a charge the way 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.
• Using data services increases demand on the battery and will reduce the length
of time it can hold a charge.
• The time required to charge the battery depends on the ambient temperature
and the age of the battery.
• When the battery is low on power, the phone plays an alert and displays a
prompt. When battery power is almost exhausted, your phone will power off
automatically.

2.2.5 Battery Saving Tips

The longevity of battery power depends on the network that you connect to, 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, switch off the screen.
• Reset the backlight timeout.
• Lower the screen brightness.
