What you need to know
- Microsoft Edge has a Sleeping Tabs feature that saves RAM usage by putting inactive tabs to sleep.
- The feature saved 273.7 Petabytes of RAM across all PCs over the last 28 days.
- Using Sleeping Tabs also reduces battery consumption by Edge.
Microsoft Edge's Sleeping Tabs feature reduces power consumption and RAM usage by putting inactive tabs to sleep. According to a recent tweet by the Microsoft Edge Dev Twitter account, the feature saved 273.7 Petabytes of RAM across all Windows PCs over the last 28 days. That's an approximate savings of 39.1 megabytes per tab.
While 39.1 megabytes may not seem like a lot, memory usage can quickly spike when several tabs are open. Power users often have 10 or more tabs open, even if only actively interacting with one or two of them. With Sleeping Tabs, users can save resources without having to open and close unused tabs.
While some PCs have quite a bit of memory, some of the best budget laptops only have 4GB of RAM. On those devices, saving a few hundred megabytes could result in a noticeable improvement in performance.
By default, the feature puts tabs to sleep after two hours, but users can customize the timeframe. People can also specify sites that they never want the browser to put to sleep.

An upgrade to Sleeping Tabs rolled out earlier this year. Starting with Edge 100, each sleeping tab saves 85% of memory and 99% CPU on average, according to Microsoft. The same update also added the ability to check how much RAM the Sleeping Tabs features saves on an individual PC. Users can select the "..." menu within the Performance section of Settings to see the information.
The latest stable version of Edge is version 102, specifically 102.1245.33. That means if your browser is up to date, you should be able to put tabs to sleep to save system resources.
