Windows laptops have always had shorter battery life compared to Apple's MacBooks, but Microsoft has made several changes over the past few years to solve this issue. Now, it is trying a new trick to improve the battery life on laptops running Windows 11, which means the battery life on your Galaxy Book will also improve with the arrival of the new feature.

Microsoft has begun testing Adaptive Battery Saver Mode on Windows 11 devices. Unlike regular Energy Saver mode, which only activates when the battery drops below a certain percentage, Adaptive Mode automatically adjusts based on the device's workload to improve battery life. It is an opt-in feature that works without changing the display brightness.

The regular Battery Saver mode drops the screen brightness by 30%, disables transparency effects, stops apps running in the background, and pauses certain data sync tasks (like OneDrive, OneNote, and Phone Link). When these changes take effect, you typically notice a sudden change in the laptop's behaviour. However, since the new Adaptive Battery Saver Mode doesn't stop background tasks or change the screen brightness, you probably won't even know when the Battery Saver mode is activated on your Galaxy Book.

This new feature is currently under testing in Windows 11's Canary Channel with build number 27898. You can opt in to this channel if you want to test this feature. Once the testing is successfully completed and Microsoft is satisfied with its performance, this new battery saver mode will roll out to all handheld devices (like portable consoles), laptops, and tablets running Windows 11.

AMD, Intel, and Qualcomm have been launching processors that are a lot more power-efficient. Those new chips, combined with Windows 11's new adaptive battery saver mode, will hopefully help bridge the gap between MacBooks and Windows laptops in terms of battery life.
