Maximizing Battery Life
White many Android phones and tablets have respectable battery life right out of the box,
there are steps you can take to extend it. You'll want to do this if you won't be able to charge
the device for a long period, such as a long flight or in a backcountry situation.
Checking Battery Usage
Swipe down from the top of the screen with two fingers to show Quick Settings. Then tap
the Battery icon to show battery drain arranged in order from highest to lowest use. Tap on
any item to show details and suggestions on reducing battery drain. You don't have control
over some apps, such as Android System and Android OS, that are always running. But you
do have some control over others, such as the screen, Wi-Fi, and Bluetooth.
