The Windows 11 25H2 update will introduce a feature called User Interaction-Aware CPU Power Management, which reduces performance during periods of inactivity to conserve power. This feature is designed to activate automatically, allowing full performance to be restored when users return to their tasks. It aims to extend battery life for laptops and save energy for desktop users, although actual energy savings may vary based on device type, power mode, and whether the device is plugged in or running on battery.
