Microsoft is introducing a new feature called Adaptive Energy Saver for Windows 11, which will automatically toggle Energy Saver mode based on user activity to maximize battery efficiency. Currently, users must manually activate Energy Saver mode, which reduces display brightness and curtails background activities. The Adaptive Energy Saver feature, currently being tested by Windows Insiders, will maintain screen brightness while managing power-intensive components like the CPU and GPU during lighter tasks. This feature is exclusive to devices with built-in batteries and is expected to be rolled out to the wider public later this year. Users can access it through Settings > System > Power & Battery once available.
