According to Microsoft reports, open tabs will need even less from your computer starting in Microsoft Edge version 100, thanks to updated ‘sleep’ tabs. A tab that has not been opened for a while and is in a sleep state uses up to 99 percent less CPU power and up to 85 percent less memory.
Inactive tabs were first tested at the end of 2020 and are now a permanent part of the browser. With the updated functionality, Microsoft promises that up to 8 percent more tabs will be put to sleep to require less PC. This works automatically; when a tab is no longer used for a while, the browser stops actively facilitating the tab. When you click the tab, it will automatically reboot.
With Microsoft Edge 100, users can also see how much processing power and memory is saved thanks to the sleep tabs. Clicking on the three horizontal dots in the top right (“…”) and selecting Performance will bring up a graph with additional information about Edge’s power and computing power savings. The new function can also be turned off with the same settings.
