Surface battery and power

Applies to: Surface Devices

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.

Your Surface alerts you when the battery’s getting low. If you don’t recharge the battery when you get this alert, your Surface will eventually save your work and shut down.

Charging your Surface

We strongly recommend that you use only the genuine Microsoft or Microsoft-licensed power supply that came with your Surface or was purchased separately to charge the battery. You can purchase Microsoft-licensed power supplies from the Microsoft Store. You can plug the charging connector into the charging port on your Surface in either direction, except on Surface 3 where the charging connector must be plugged in with cable extending down and the LED indicator facing you.

Is it charging?

While your Surface is charging, a small light appears on the connector to show your Surface is getting power, and the battery status icon will show an electrical plug.

If the light doesn’t appear or the icon doesn’t show that the battery is charging (you don’t see the electrical plug on the icon), see Surface won’t turn on or wake from sleep.

How long does it take to charge Surface?

It can take a few hours to fully charge the battery when it’s empty. It can take longer if you’re using your Surface for power-intensive activities like gaming or video streaming while you’re charging it. To see the estimated time remaining to fully charge the battery, select the battery icon on the right side of the taskbar.

Surface Book

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% charge will be charged first. After both batteries have been charged to 20%, both of them are charged at the same time.

Making your battery last

Choose a Power Mode for the best battery life and performance

On some Surface models you can select a Power Mode, which affects how much battery life and the performance you can get from your Surface.

To switch to a different Power Mode, select the battery icon in the Windows taskbar. If you want to save power to write an email or finish a movie, move the slider to a lower setting, like Recommended or Battery saver. Or, if you need better performance for playing a game or using a Windows Mixed Reality headset, move the slider to a higher setting like Best performance.

General battery tips and tricks

Get the latest Windows and Surface updates

Installing the latest updates will help keep your Surface performing at its best. To see how, go to Install Surface and Windows updates.

To get to these settings, type power & sleep into the search box on the taskbar.

Follow these tips to extend the lifetime of your battery:

  • Keep it cool. 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.
  • Once a month, recharge when it’s 10% or lower. You can recharge the battery whenever you want But, However, it’s best to let the battery run to below 10% at least once per month before you recharge it.

If the battery’s defective, there’s a warranty. For more details, see Surface standard warranty and Microsoft Complete for Surface.
