Windows 11 is getting adaptive power saver

It appears that Microsoft is working on additional improvements for energy-saving capabilities in Windows 11. The company has already introduced several new features, including an energy saver for desktop computers, and now, more options are on the way for mobile devices.

Windows enthusiasts discovered that the latest Windows 11 preview builds from the Dev and Beta Channels (the same builds that brought back a long-requested taskbar feature from Windows 10) have a hidden "Adaptive Energy Saver," which is expected to automatically kick in energy saving depending on what you do with your PC, its current charge level, resource load, and more. It is related to the "Windows Health and Optimized Experience" service, which was quietly introduced in the latest Canary Channel build.

The new adaptive energy saver is now available on desktop PCs even when force-enabled. This feature appears to be intended for mobile devices only, such as laptops and tablets. If you have one with the latest preview build from the Dev or Beta Channel, you can turn on the new energy saver with the ViVeTool:

1. Download ViVeTool from GitHub and unpack the files in a convenient and easy-to-find folder.
2. Run Command Prompt as Administrator and navigate to the folder containing the ViVeTool files with the CD command. For example, if you have placed ViveTool in C:\Vive, type CD C:\Vive.
3. Type vivetool /enable /id:56401475 and press Enter.
4. Restart your computer.

Brandon LeBlanc from the Windows Insider team has confirmed that developers are working on the adaptive energy saver. However, he also added that the feature does not work properly as of right now, which is why we have not seen any official announcements:

In other Windows Insider news, a nostalgic bug currently replaces Windows 11's stock startup sound with one from Windows Vista. Microsoft acknowledged this issue, and it should be fixed in future Windows 11 builds
