Optimizing battery life

Extend the life of your battery
- extend your battery’s life between charges by turning off features that you don’t need.
  Turn off radios that you aren’t using. If you aren’t using Wi-Fi, Bluetooth, or GPS, use the Settings
  application to turn them off. See Wireless & networks and Location & security settings.
- 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.
- Use the Power Control widget to check and control the status of radios, the display brightness, and syncing.
- If you know you won’t be near a mobile or Wi-Fi network for a while, switch to Airplane mode.
  Your phone uses extra power to search for mobile networks.

Check the battery charge level
On the Home screen, press Menu and touch Settings > About phone > Status.
The battery status (charging, discharging) and level (as a percentage of fully charged) are displayed at the top of the screen.

Monitor and control what uses the battery
The Battery Use screen shows which applications consume the most battery power. You can also use it to turn off applications that you’ve downloaded, if they are consuming too much power.
