Microsoft Edge is a browser whose market share keeps improving, and it's not only because it's offered as the default app on Windows 11.

Edge is really a fully featured browser, and Microsoft keeps improving it with new functionality regularly, adding new capabilities that make it faster, more stable, and more power efficient regardless of platform.

One of the biggest additions to the advantage feature arsenal is support for Sleeping Tabs, a tool whose main role is to simply put inactive tabs to sleep. This means they no more use resources without anyone's knowledge, with the browser therefore reducing the battery consumption when Microsoft Edge is running.

Microsoft has recently revealed on Twitter that Microsoft Edge managed to put to sleep forget about, at least 6 billion tabs in just 30 days.

"Use sleeping tabs in order to save resources? You aren't alone! Over the past 4 weeks on Windows devices, we slept 6 billion tabs resulting in a savings of 273.7 Petabytes of RAM. That's roughly 39.1 megabytes saved per tab," the organization announced.

Sleeping tabs have been around for some time, but an essential update was announced in April this year when Microsoft added an improved behavior to enhance resource saving.

"Beginning in Microsoft Edge 100, we've updated sleeping tabs to enable pages that are sharing a browsing instance with another page to now go to sleep. With this particular change, 8% more an eye on average will sleep, helping you save much more resources! On average, each sleeping tab saves 85% of memory and 99% CPU for Microsoft Edge. We've also added a means for you to view just how much memory sleeping tabs is saving you by going to Performance under the "…" ("Settings and more") menu," Microsoft announced at that point.

Sleeping tabs can be found in Microsoft Edge on all desktop platforms in which the browser could be installed.
