Skip the Bells and Whistles, Save Your Cell Battery
All the nifty added features of your phone tax the battery. Get days of extra juice by turning off Bluetooth, turning down the screen brightness, and setting the display to dim after five seconds. Also disable any GPS locator (it will still work for 911), and unselect 'Check for Network Time,' setting it manually instead. And if you're out of signal range, turn the phone off, as it'll burn extra power searching for a cell tower.
