What Is Efficiency Mode
The efficiency mode feature is available in Windows 11 22h2’s Task Manager app. This feature is not available for all applications and processes in Task Manager. You can enable or disable efficiency mode only for supported processes. some applications do not support this feature since enabling this feature reduces the priority of using system resources.
What Happens When You Enable Efficiency Mode?
When you enable efficiency mode for a process or program, Windows lowers the process’s priority. By default, Windows assigns a priority to each process based on its requirements and current tasks. This priority is sometimes miscalculated or incorrectly requested by a program or process.
In this case, these processes end up using more resources and end up interfering with other high-priority tasks that require those resources. This can lead to high battery usage, poor UI response times, lag, and even crashes on bottlenecked systems.
Tip: If the efficiency mode causes your PC to crash, then your important data may get lost since the PC can’t boot normally. Thus, you had better back up your system or important data in advance. The professional backup tool – MiniTool ShadowMaker is recommended.
