Windows 11 Expands Dark Mode for Samsung Galaxy Books

23 Oct 2025

Microsoft is enhancing the dark mode in Windows 11, aiming to improve battery life on OLED laptops such as Samsung Galaxy Books. The update, currently in the Windows 11 Insider Preview, expands dark mode compatibility across more user interface elements.

UI Elements and Features

The Windows 11 Insider Preview Build 26220.6772 for the Dev Channel introduces an expanded dark mode that includes additional UI elements. Users will now see dark mode applied to copy, move, and delete dialogs, progress bars, and various error and confirmation dialogs. This enhancement seeks to address prior inconsistencies, improving both user experience and energy efficiency.

Impact on OLED Devices

The change is particularly beneficial for OLED display devices, where dark pixels consume less energy. This update should reduce occurrences of light-themed elements, thereby extending battery life. Samsung Galaxy Book users are expected to notice improvements once the update reaches the stable channel, though no official release date for this has been set yet.

These enhancements signal Microsoft's commitment to refining visual consistency and device performance through better dark mode integration.
