Surface battery and power

Your Surface uses 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.


How much battery charge is left?

The battery status appears in a few places:
  • Lock screen. When you wake your Surface, the battery status appears in the bottom-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 per cent remaining.
Battery icon in the taskbar

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 Surface

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

Important
Your Surface is designed to work best with the included power supply. Using a third-party power supply may result in slow charging. For more information about how to take care of your power supply, see Surface Safety Information.

Charge your Surface Pro, Surface Pro 2 or Surface Pro 3

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

Surface Pro 3: When your Surface Pro 3 battery is charged fully, it should last for up to nine hours for web browsing.1

1 Testing consisted of full battery discharge while Internet browsing over Wi-Fi. Internet browsing was tested browsing 25 popular webpages. All settings were default except: Wi-Fi was associated with a network, Auto-Brightness was disabled, and the Bluetooth Radio was turned off. Battery life varies with settings, usage and other factors. Games, films and music sold separately.

Charge your 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.

When your Surface 3 battery is charged fully, it should last for up to 10 hours of video playback.2

2 Testing conducted by Microsoft in March 2015 using 128 and 64 GB units with 4 GB RAM. Testing consisted of full battery discharge during video playback. All settings were default except: Wi-Fi was associated with a network and Auto-Brightness disabled. Battery life varies significantly with settings, usage and other factors.

Is it charging?

While your Surface is charging, a small light appears on the connector to show that it 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 bottom-right corner 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 my Surface?

It takes two to four hours to charge the battery fully from an empty state. It can take longer if you’re actively using your Surface for power-intensive activities like gaming or video streaming.

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 Pro models only)

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 only for charging, not for data transfer. Your Surface won’t recognise devices connected to the USB port. 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, 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. 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:  Go to Start Windows logo > 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.
Note

A power plan is a collection of hardware and system settings that control how your Surface uses power.

Turn off your Surface

  • Go to Start Windows logo > Power > Shut down.

Battery: Making it last

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

  • Reduce the screen brightness. Go to Start Windows logo > Settings > System > Display, and 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 Centre Action Centre icon in taskbar on the taskbar, 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. To do this, select the Wi-Fi icon Wi-Fi icon in the taskbar, and select Wi-Fi. When Wi-Fi is off, Wi-Fi is dimmed.
  • Turn on Airplane mode. If you don’t need Wi-Fi and Bluetooth for a while, turn on Airplane mode to conserve battery life. Select Wi-Fi Wi-Fi icon > Airplane mode. When Airplane mode is off, Airplane mode is dimmed.
  • 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.
  • Choose a power plan that saves power. A power plan is a collection of settings that control how your Surface uses power.
  • Turn off mobile broadband. If you have a Surface 3 model with mobile broadband (4G LTE), you can switch off your mobile broadband connection to conserve battery power.
  • 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, 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 look after your power cord:

  • Avoid twisting or pinching your power cord.
  • Don’t wrap your power cord too tightly, especially around the power pack. Instead try to wrap it using loose coils rather than tight angles.
Correct: Cord wrapped loosely
