Windows Task Manager’s “Efficiency Mode” may cause Google Chrome to freeze, here is how to disable it permanently, rather than temporarily turning it off for Chrome’s sub-processes.
Microsoft has launched efficiency mode for Windows 11 with version 22H2 to reduce Power and CPU consumption. Enabling Efficiency mode for app sub-processes leads to increased battery life, reduced fan noise, and thermal throttling. It ensures certain processes don’t stress the CPU, resulting in faster foreground responsiveness and better energy efficiency.
Efficiency Mode is Windows 11-only feature, not related to any specific App. It can be noticed in Task Manager, where the processes that use the feature appear with a green leaf to indicate limited resources being used by the process.
When efficiency mode is applied to a process, it reduces the process’s priority to low and deploys EcoQoS, a quality service that reduces clock speed for efficient tasks.
Normally, most web browsers including Microsoft Edge, Google Chrome, and Firefox, use Efficiency mode.
While the feature brings the benefits of improved performance and reduced Power consumption to the device, it may sometimes cause apps to freeze or hang.
Google Chrome is considered one example of an app experiencing such issues. When you check Task Manager, the feature gets enabled, if you disable for specific processes, the efficiency mode gets disabled. However, The issue with this method is efficiency mode gets re-enabled for Chrome processes again.
Generally, to enable or disable efficiency mode for an app, right-click on its process and check or uncheck Efficiency mode.
