Activate the Android Power Strip

An important feature in Android is its built-in power tune-up widget. Here, you're able to quickly disconnect all the phone's battery-destroying features, like Wi-Fi, Bluetooth and the Great Batter Killer that is GPS.

To install it, long-press on the screen and choose widgets.  Look for "Power Tune-Up" and choose a widget to add to your apps.  Once installed, you will have quick access to some important power settings.
