Video: Optimize your Surface for battery life
This video is available in English only.
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.
|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
Use the power supply that came with your Surface to charge the battery. 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.
Your Surface is designed to work best with the power supply it came with. Using a third-party power supply might slow down the charging speed.
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, Windows won’t start, or the battery won’t charge.
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.
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. When both batteries are at 20%, the clipboard will charge to 85%, and then both batteries will charge to 100%.
Having battery or power problems?
Power supplies with a USB charging port (Surface Book and Surface Pro only)
If the power supply that came with your Surface has 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 transferring data from a device to your Surface.
For more info, see Connect a USB mouse, printer, and more.
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.

Adjust other settings
There are a few settings you can adjust to save battery power:
- Turn on the Save me power when my device knows I’m away setting.
- Adjust the When my PC is asleep and on battery power, disconnect from the network setting (choose Always or When I close the lid instead of Never).

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.
