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 aren’t using. If you aren’t using Wi-Fi, Bluetooth, or GPRS,
use the Setting application to turn them off.
Turn down screen brightness and set a shorter screen timeout.
If you don’t need them, turn off automatic syncing for Gmail, Calendar, Contacts,
and other applications.
Note: On the Home screen, press Menu icon and touch Settings > About phone > Battery use.
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’re currently connected to one, how long you were running on battery power before you
connected to a charger. Then 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.
