Microsoft renames Performance Mode into Efficiency Mode in Edge

Back in April 2021, Microsoft shared details about the new Performance Mode coming soon to the Edge browser. It combines several performance-optimizing tools to help your browser run faster and consume less CPU/RAM resources. Although Performance Mode in Edge still hides behind a command (you can learn how to enable Performance Mode in Microsoft Edge in a dedicated post,) Microsoft has already renamed it to Efficiency Mode. Moreover, Efficiency Mode now has a dedicated button on the toolbar, allowing you to turn it on or off with a single click.


Efficiency Mode in Microsoft Edge puts inactive tabs to sleep after five minutes of inactivity. Also, it reduces CPU load that, in turn, may reduce video and animation smoothness. As a result, Microsoft Edge consumes fewer resources and improves the battery life of your computer. Still, Microsoft makes it clear right away that the effect of Efficiency Mode varies depending on your hardware/software configuration and, curiously, your browsing habits.

A new name also brings new controls for Efficiency Mode in Microsoft Edge. You can now place a dedicated Performance button on the Edge's toolbar.
