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:
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.
