Surface Pro battery and power

Surface Pro, Surface Pro 2 and Surface Pro 3 use an internal lithium-ion battery designed to go everywhere you go. The amount of time your battery lasts varies depending on the kinds of things you do with your Surface and your power plan.


How much battery charge is left?

The battery status appears in a few places:

Lock screen: When you wake Surface, the battery status appears on the lock screen (bottom-left corner).

Charms: When you swipe in from the right edge of the screen, the battery status appears in the bottom-left corner of the screen.

Desktop taskbar: Battery status appears in the bottom-right in the taskbar. Tap or click the battery icon for info about the charging and battery status, including the percent remaining.

To learn more about battery status, see Battery: Frequently asked questions.

Windows alerts you when the battery starts to get low. When you’re alerted, be sure to attach the power supply. If you don’t recharge the battery, Surface will eventually save your work and shut down.

Charging Surface

When the battery is low, charge your Surface using the included power supply. Here’s how:

Step 1:  Connect the two parts of the power cable.
Step 2:  Insert the plug into an electrical outlet or power strip.
Step 3:  Connect the power cord securely to the charging port on your Surface.

Once connected, a small light appears at the end of the connector to show that Surface is getting power. If the light doesn’t appear, see Surface battery won’t charge.

To make sure your Surface is charging, swipe in from the right edge of the screen and look in the lower-left corner for the battery status. When charging, the battery icon appears with an electrical plug. Once the battery is fully charged, you can remove the power cord from the charging port.

How long does it take to charge Surface?

It takes 2-4 hours to fully charge your Surface Pro, Surface Pro 2 or Surface Pro 3 battery from an empty state.

USB charging port

The power supply that comes with Surface Pro models includes a USB port. You can use it to charge other devices, like a phone, while your Surface charges.

The USB port on the power supply is for charging only, not for data transfer. Devices connected to the USB port aren’t recognised by Surface. If you want to use a USB device, plug it into the USB port on Surface. For more info, see Connect a USB mouse, printer and more.

On, off, sleep, restart

If you don’t use your Surface for a while, the screen may dim or Surface Pro may go into a power-saving sleep state to preserve battery life. You can change the settings for when the screen dims and turns off.

Change when the display dims and turns off

You can change when the screen dims or turns off. Here’s how:

Step 1:  Swipe in from the right edge of the screen, then tap Settings.
(If you're using a mouse, point to the bottom-right corner of the screen, move the mouse pointer up, then click Settings.)
Step 2:  Tap or click Change PC settings, then tap or click PC and devices.
Step 3: Tap or click Power and sleep, then, under Screen, select when you want to dim the display when Surface is running on battery and when it’s plugged in.
Note
A power plan is a collection of hardware and system settings that control how your Surface uses power. For more info about power plans, see Power Plans: Frequently asked questions.

Turn off Surface

Step 1:  Swipe in from the right edge of the screen, and then tap Settings.
(If you're using a mouse, point to the bottom-right corner of the screen, move the mouse pointer up, then click Settings.)
Step 2:  Tap or click Power, and then tap or click Shut down.

Battery: Making 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, then move the slider. The brighter the screen, the more power it uses.
  • 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, then slide Wi-Fi to Off.
  • Turn on Airplane mode. If you don’t need Wi-Fi and Bluetooth for a while, this is another action you can take to conserve battery life. Open the Settings charm, tap or click the wireless network icon, then slide Airplane mode to On.
  • Turn off or remove devices that you aren't using. Many USB devices use power just by being connected, so you might want to unplug these devices when you're not using them.
  • Choose a power plan that saves power. A power plan is a collection of settings that control how your Surface uses power. To learn about power plans, see Power plans: Frequently asked questions.

Battery care

  • Operating temperature. Surface is designed to work between 32°F and 95°F (or 0°C to 35°C). Lithium-ion batteries are sensitive to high temperatures, so keep your Surface out of the sun and don’t leave it in a hot car.
  • Recharge anytime. The battery doesn’t need to be empty or low before you recharge. You can recharge the battery whenever you’d like. However, it’s best to let the battery run to below 10 percent at least once per month before you recharge it.
  • Battery warranty. If your Surface battery is found to be defective during the warranty period, it is covered under the standard Surface Warranty. For more details about the Surface Warranty or for extended warranty coverage, see Surface standard warranty and Microsoft Complete for Surface.
