Battery: Make it last

Here are some ways you can help make your battery last longer:

 Reduce the screen brightness. Open the Settings charm, tap or click Screen, and then adjust the slider.

The brighter the screen, the more power it uses.

 Choose a power plan that saves power. A power plan is a collection of settings that control how your

Surface uses power. To learn more about power plans, see Power plans: Frequently asked questions on

Windows.com.

 Turn off or remove devices that you aren't using. Many USB devices use power when connected, so

you might want to unplug devices that you're not using.

 Turn off Wi-Fi. If you don’t need Wi-Fi for a while, you can turn it off to conserve battery life. To do this,

open the Settings charm, tap the wireless network icon, and turn on Airplane mode.
