Charge your Galaxy Book

Just like a phone or tablet, your Galaxy Book needs to be charged to keep its battery going. Use the included charger to give it a charge whenever it needs some juice. We also have some tips for extending the battery life, so it will last and last.

Important: Use only Samsung-approved chargers, batteries, and cables. Samsung accessories are designed to maximize battery life. Using other accessories may invalidate your warranty and cause damage.

Charge the battery

Galaxy Book models use a Samsung USB-C charger. They also all support fast charging! However, the Galaxy Book S comes with a 25W charger instead of 15W. If you ever want another charger, you can buy one from or check out our 45W USB-C charger.

To charge your device, connect the charger's USB cable to the power adapter. Insert the cable into the Galaxy Book's charging port. Next, plug the adapter into a wall socket. After the battery is fully charged, the Power LED will change color. Disconnect your Galaxy Book from the charger.

You can also connect Thunderbolt compatible chargers to the Thunderbolt 4 port on the Galaxy Book Pro and Pro 360.

  • The Battery life extender feature automatically stops your Galaxy Book from charging past 85%. This helps prolong the overall battery life of the device. You can disable Battery life extender if you want to charge the Galaxy Book to 100%.

Battery charging tips and precautions

Here are some things to take into consideration when it comes to charging your Galaxy Book:

  • The Galaxy Book can be used while it is charging, but it will take longer to fully charge.

  • Using a power source other than the adapter, such as a computer, may result in a slower charge.

  • If the battery does not charge properly, take your Galaxy Book and charger to the nearest Samsung Service Center.

  • If the battery is completely discharged, the Galaxy Book cannot be turned on immediately after connecting the charger. Let the battery charge for a few minutes before turning on your Galaxy Book.
