Microsoft is currently testing a new Windows 11 feature called adaptive energy saver, designed to extend battery life on portable devices. Unlike traditional energy-saving modes that activate based on remaining battery percentage, this new approach evaluates the system’s workload and power state to determine when to enable or disable energy saver mode.
It’s an opt-in feature and is being previewed in the Canary Channel for Windows Insiders, meaning some users may already see it available.
What makes the adaptive energy saver particularly discreet is that it does not alter screen brightness, a common indicator of energy-saving settings. Instead, it operates behind the scenes, dimming certain visual effects like transparency, reducing background activity, and maintaining overall system efficiency without disrupting user experience.
The feature is exclusive to battery-powered devices such as laptops, tablets, and handhelds, and can be accessed via Settings > System > Power & battery, giving users control over how and when it’s applied.
Adaptive energy saver represents a smarter, less intrusive way to conserve power and improve device performance, especially for users who multitask or rely heavily on their laptops throughout the day.
