windows 11 efficiency mode

Windows 11 Efficiency mode is a power-saving feature introduced with the 22H2 update that throttles background processes to reduce thermal load and extend battery life. In Task Manager, users can manually enable Efficiency mode on specific processes, which tells Windows to deprioritize their CPU and resource usage. This feature can cause noticeable slowdowns in applications like Google Chrome, especially when they are running in the background or not set as the active window. The interaction between Efficiency mode and Chromium-based browsers is a common topic on WindowsForum, where users troubleshoot performance issues and share tips for managing which processes are throttled. Understanding how to configure Efficiency mode helps balance system responsiveness with energy efficiency.
