Android basics 62 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 extend the life of your battery S 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" on page 309 and "Location & security settings" on page 316. (The GPS receiver is only turned on when you're using an application that makes use of it.) S Turn down screen brightness and set a shorter screen timeout. See "Sound & display settings screen" on page 314. S If you don't need them, turn off automatic syncing for Gmail, Calendar, Contacts, and other applications. See "Configuring account sync and display options" on page 115. S Use the Power Control widget to check and control the status of radios, the display brightness, and syncing. Adding widgets is described in "Customizing the Home screen" on page 58. To check the battery charge level S 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. NOUG-2.1-update1-105 Nexus One User's Guide
