This feature is based on Chromium’s “freezing” technology. When enabled, the inactive tabs go to sleep after a set amount of time to minimize the resource usage. Thankfully, a sleeping tab resumes automatically when clicked instead of being completely reloaded.

This could be highly useful for people who moved out from Chrome to Edge for lesser CPU usage and better battery life.
