Android basics 46 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. 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 355 and "Location & security settings" on page 365. (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 "Display settings" on page 364. 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 131. 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 43. S If you know you won't be near a mobile or Wi-Fi network for a while, switch to Airplane mode. You phone uses extra power to search for mobile networks. See "Disable phone calls (Airplane mode)" on page 79. 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. AUG-2.3-103 Android User's Guide
