Here are some tips for extending your battery life when using TweetCaster:
a. Turn off Background Notifications. Tap the menu and select "Settings." Scroll down and tap "Notifications" and then uncheck the box for Background Notifications. With background notifications turned off, you will no longer be notified of new tweets after exiting TweetCaster.
b. Turn off Auto-refresh. Tap the menu and select "Settings." Scroll down and uncheck the box for Auto-refresh. With auto refresh enabled, you will need to manually refresh TweetCaster, but it will save battery life.
NOTE: When Auto-Refresh is disabled, the Notifications item in settings will be grayed out since disabling Auto-refresh automatically disables background notifications.
c. Remove the widget – If you've installed the TweetCaster widget, it will use more battery than having just the app installed.
