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:
If you are not using the following turn them off:
Radio, Wi-Fi, Bluetooth, or GPRS. Use the Setting application to turn them off. Turn down the brightness of the screen
and set a shorter display sleep time. Turn off automatic syncing for Gmail, Calendar, Contacts, and other applications.
Note: On the Home screen touch Settings >Device > Battery. The Battery Usage screen lists the applications that
have been using the battery, from highest to least battery usage. 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 has been using the battery power during that time is
displayed, in order of the amount of power used. Touch an application in the Battery Usage screen to learn more about
its power consumption. Different applications offer different kind of information.

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.
