Better battery and resource usage

What’s ‘Performance mode’ feature on Microsoft Edge

Microsoft Edge now includes a "Performance mode" feature, and here's what it actually does.

Microsoft Edge performance mode

On Microsoft Edge, “Performance mode” is a feature part of the “Optimize Performance” settings, and as the name implies, it has been designed to improve the system performance. When the mode is enabled, Microsoft Edge will optimize the performance by applying settings to save battery life and minimize memory and processor utilization.

The improvements might vary depending on the computer type and hardware and how you use the browser. However, typically, the browse will put inactive tabs to sleep after five minutes, minimize animations, and reduce video playback quality.

Although this implementation will noticeably improve performance, desktop computers won’t see any benefits. Instead, this is a feature designed for laptops and similar low-end devices to save battery by minimizing system resource usage without affecting the overall experience.

At the time of this writing, Microsoft Edge Performance mode is still under development in the Canary channel for Windows 10 and macOS users. However, as soon as it’s ready, we can expect the company to start rolling it out to everyone.

If you want to test the feature now, you only need to append this line: --enable-features=msPerformanceModeToggle at the end of the line in the Target field for the browser shortcut. The Target line should looks like this: "C:\Users\ACCOUNT-NAME\AppData\Local\Microsoft\Edge SxS\Application\msedge.exe" --profile-directory=Default --enable-features=msPerformanceModeToggle.
