Charge your Galaxy Book

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 Galaxy Book Pro 360.

• Decrease the screen's brightness.

• Close any unnecessary or unused apps.

• Turn off Bluetooth and Wi-Fi if they are not being used.

• When you are not using your Galaxy Book, enable Sleep mode by pressing the Power key.

• Turn on Battery saver mode. Select the Battery icon in the taskbar and then select the switch to activate it. Depending on your model, you may need to select Battery settings first.

• The Battery life extender feature automatically stops your Galaxy Book from charging past 80% or 85%. This helps prolong the overall battery life of the device. However, you can disable Battery life extender if you want to charge the Galaxy Book to 100%.

• 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 is not charging properly, take your Galaxy Book and charger to the nearest Samsung Service Center for inspection.

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

• While charging, the Galaxy Book and the charger may become hot. This is normal and should not affect the Galaxy Book's lifespan or performance. If the battery gets too hot, it may stop charging.
