Optimizing battery life
You can extend your battery’s life between charges by turning off features that you don’t 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:
1.
Turn off radios that you aren’t using. If you aren’t using Wi-Fi, Bluetooth, use the Setting application to turn them off.
2.
Turn down screen brightness and set a shorter screen timeout.
3.
If you don’t need them, turn off automatic syncing for Gmail, Calendar, Contacts, and other applications.
4.
Long Press of the central button will kill the Apps running in the background.
Note: On the Home screen, press Settings > Scroll to 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’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. Scroll and select an application or Service from the list. Once
selected, press the central button to learn details about its power consumption. Different applications offer different kinds of information.
