With the new Sleeping Tabs feature, you can reduce Edge RAM usage by 25%. Here are the steps to enable Sleeping Tabs in Microsoft Edge.
In a recent update, Microsoft added a new feature called Sleeping Tabs to the Edge browser. As you can guess from the name, the Sleeping Tabs feature will put unused tabs to sleep after a set amount of time. As you know, every tab in the Edge browser consumes some amount of memory or RAM to run. So the more tabs you have in the Edge browser, the more memory it will consume. This is especially true for tabs with heavy content like media playback, big spreadsheets, etc.
If you are like me who opens a lot of tabs and forgets to close them, allowing the Edge browser to suspend unused tabs will free up a lot of memory. The good thing is, the suspended tabs will auto-reload to show the content when you select the tab. To suspend unused tabs in the Edge browser, you need to enable Sleeping Tabs and configure it as needed.
So, without ado, let me guide you through the steps to enable Sleeping Tabs and change Sleeping Tabs timer in the Microsoft Edge browser.

As of writing this, you have to first turn on Sleeping Tabs in Edge Flags and then on the Settings app. It is pretty easy to do. Follow the steps below.
