Change Sleeping Tabs Timeout in Microsoft Edge

Here is how you can change Sleeping Tabs Timeout in Microsoft Edge. To improve memory and CPU utilization of the browser, Microsoft has added a new "sleeping tabs" feature to the Edge browser. It extends device's battery life and reduces its power consumption by putting background tabs into the idle state.


Similar features already exist in a number of modern browsers. You must have heard about tab hibernation in Vivaldi. Chrome and Firefox offer something similar. Microsoft Edge now offers the similar option. Called "Sleeping Tabs", it can be enabled or disabled on demand. See Enable or Disable Sleeping Tabs in Microsoft Edge.

Microsoft used Chromium's tab freezing technology to create sleeping tabs. This feature allows inactive background tabs to “go to sleep,” releasing system resources after a set amount of time. These resources include both memory and CPU and can be used for new or existing tabs or other applications running on your device.

By default, tabs are set to go to sleep after two hours of inactivity. If two hours isn’t right for you, you can choose a different time interval.

This post will show you how to change the Sleeping Tabs timeout in the Edge browser. We will review two methods of doing that.
