Optimizing battery life
You can extend your battery’s life between charges by turning off features that you do not need. You can also monitor
how applications and system resources consume battery power. To guarantee the optimal performance of your battery,
please stick to the following rules:
Turn off radios that you are not using. If you are not using Wi-Fi, Bluetooth, or GPRS, use the Setting application
to turn them off. Turn down the brightness of the screen and set a shorter screen timeout. Turn off automatic syncing for
Gmail, Calendar, Contacts, and other applications.
Note: On the Home screen, press Menu icon and touch Settings > Device > Battery. The Battery Use screen lists
the applications that have been using the battery, from greatest to least battery use. The top of the screen displays the
time since you were last connected to a charger or, if you are currently connected to one, how long you were running on
battery power before you connected to a charger. Each application or service that used battery power during that time
is displayed, in order of the amount of power they used. Touch an application in the Battery Use screen to learn details
about its power consumption. Different applications offer different kinds of information.
Linking to the Networks and devices
Your phone can connect to a variety of networks and devices, including mobile networks for voice and data transmission,
Wi-Fi data networks, and Bluetooth devices, such as headsets. You can also connect your phone to a computer, to
transfer les from your phone’s SD card and share your phone’s mobile data connection via USB.
