Operating system:

Surface battery and power

Your Surface uses an internal lithium-ion battery. The amount of time your battery lasts will vary depending on the kinds of things you do with your Surface.

How much battery charge is left?

The battery status appears in several places:
  • Lock screen. When you wake your Surface, the battery status appears in the lower-right corner of the lock screen.
Battery icon on the lock screen
  • Desktop taskbar. Battery status appears at the right side of the taskbar. Select the battery icon for info about the charging and battery status, including the percent remaining.

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, your Surface will eventually save your work and shut down.

Charging your Surface

When the battery is low, charge your Surface using the included power supply.

Your Surface is designed to work best with the included power supply. Using a third-party power supply may result in slow charging.

Charge Surface Pro models and Surface Book

Step 1: Connect the two parts of the power cord.
Step 2: Connect the power cord securely to the charging port on your Surface.
Step 3: Plug the power supply into an electrical outlet.

Charge Surface 3

Step 1: Plug the Micro USB connector into the Micro USB charging port with the power cord extending downward and the light on the connector facing toward you.
Step 2: Plug the full-size USB connector on the other end of the cord into the power supply.
Step 3: Plug the power supply into an electrical outlet.

Is it charging?

While your Surface is charging, a small light appears on the connector to show your Surface is getting power. If the light doesn’t appear, see Surface won’t turn on, Windows won’t start, or the battery won’t charge.

To make sure your Surface is charging, look in the lower-left corner of the taskbar for the battery status. When your Surface is 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 can take a few hours to charge the battery fully from an empty state. It can take longer if you’re using your Surface for power-intensive activities like gaming or video streaming while you’re charging it.

The batteries in Surface Book may also charge at different rates, depending on the power state of each battery. Whichever battery has less than 20 percent remaining charge will be charged first. When both batteries reach this level, the clipboard will charge to 85 percent, and then both batteries will charge to 100 percent.

Having battery or power problems?

If your Surface won’t turn on, the battery isn’t charging, or you see a low-battery warning, see Surface won’t turn on, Windows won’t start, or the battery won’t charge.

USB charging port (Surface Book and Surface Pro models only)

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


The Surface Pro 4 with Core M processor does not have a USB port on the charger.

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

On, off, sleep, and restart

If you don’t use your Surface for a while, the screen may dim or your Surface may go into a power-saving sleep state to preserve battery life. In Settings, you can change when your Surface enters this power-saving state.

Change when the display dims and turns off

Step 1: Go to Start Windows logo, and select Settings > System > Power and sleep.
Step 2: Under Screen, select when you want to dim the display when your Surface is running on battery and when it’s plugged in.

Turn off your Surface

  • Go to Start Windows logo, and select Power > Shut down.

Making your battery last

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

Reduce the screen brightness. Here’s how:

Step 1: Go to Start Windows logo, and select Settings > System > Display.
Step 2: Move the slider under Brightness level. The brighter the screen, the more power it uses.
You can also change the brightness by swiping in from the right edge of your screen or selecting Action Center Action Center icon in taskbar on the taskbar and then selecting Brightness Brightness icon in Notifications

Turn off Wi-Fi. If you don’t need Wi-Fi for a while, you can turn it off to conserve battery life. Here’s how:

Step 1: Go to Start Windows logo, and select Settings > Network & Internet > Wi-Fi.
Step 2: Under Wi-Fi, move the toggle to Off.

Turn on Airplane mode. If you don’t need Wi-Fi and Bluetooth for a while, turn on Airplane mode to conserve battery life. Here’s how:

Step 1: Go to Start Windows logo, and select Settings > Network & Internet > Airplane mode.
Step 2: Under Airplane mode, move the toggle to On.

Turn on Battery saver. If your Surface is running low on power, turn on Battery saver to save energy. Here’s how:

Step 1: Select Battery Windows logo in the lower-left corner of the taskbar.
Step 2: Select Battery saver.

Turn off or remove devices 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.

Use a powered USB hub. Using an unpowered USB device can quickly drain your battery. Plug the accessory into a powered USB hub plugged into an electrical outlet, and then plug the hub into your Surface.

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 any time. The battery doesn’t need to be empty or low before you recharge. You can recharge the battery whenever you 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.

Power cord care

Power cords, like any other metal wire or cable, can be weakened or damaged if repeatedly twisted or bent in the same spot. Here are a few things you can do to keep your power cord from being damaged:

  • Avoid twisting or pinching your power cord.
  • Don’t wrap your power cord too tightly, especially around the power brick. Instead, wrap it using loose coils rather than tight angles.
