A feature that first appeared in Windows 11 Dev Channel build 23424 is now available for Insiders who are part of the Canary Channel. The said update will upgrade the system to Windows 11 Build 25346 and comes equipped with a new feature for Content Adaptive Brightness Control (CABC) that can be used when a laptop or 2-in-1 is connected. Interested individuals can easily download and install the build via Windows Update or obtain ISOs directly from Microsoft.
In addition to the new feature, the update includes several other improvements and changes. Of particular note is the revamped connection bar for remote desktop sessions. Kindly refer to our detailed report for a thorough compilation of all the new features, modifications, and enhancements.
CABC (Content-Adaptive Backlight Control) is a new functionality introduced by Microsoft in 2021 alongside Windows 11. This feature is designed to optimize screen brightness and contrast levels based on the visual content displayed on the device’s built-in screen. For example, the brightness and contrast may be automatically adjusted when switching between a dark scene and a bright one in a visual medium.
With the release of Build 25346, CABC has been activated for laptops and 2-in-1 devices that are plugged in. This move is expected to improve the overall user experience while reducing energy consumption and prolonging battery life. It is worth noting, however, that changes resulting from this functionality may not be immediately perceptible to most users but should result in a noticeable drop in energy usage.
According to Microsoft, users can manage the CABC feature by accessing Windows Settings and navigating to System > Display > Brightness & Color. A new drop-down menu on this page allows users to select from three options: Off, Always, and “On Battery Only.” These options correspond to Windows 11’s CABC feature.
To optimize battery consumption, “On Battery Only” is set as the default option for battery-powered devices like laptops and 2-in-1s. As the tech giant is still refining this feature, testers are encouraged to utilize the “Always” option.
