Browsers are notorious for hogging system resources. Open a dozen tabs on a laptop or PC with low RAM and could be staring at a blank wall for minutes. It slows you down and can be quite annoying if it happens regularly. Microsoft's Edge has addressed this issue with its Sleeping Tabs feature.

This feature helps you optimize the system resources by putting inactive tabs to sleep, pretty much like the sleeping apps on your Android phone. So, quite naturally, it reduces the load on the CPU, and in the process, lets you have a distraction-free routine.

So if you use Microsoft Edge, or plan to shift to it soon, here’s how you can enable Sleeping Tabs.

How Do Sleeping Tabs Work

Browsers tend to hogg up system resources, and this comes to the picture if you have opened dozens of tabs together. Even if you are not using those tabs actively, they still use up resources that may throttle browser performance.

Putting tabs to sleep may reduce memory usage by around 32%

Sleeping tabs help to prevent just that. It puts inactive tabs to sleep and thus frees up the CPU’s resources. As per Microsoft, putting tabs to sleep may reduce memory usage by around 32% on average. At the same time, it also puts less pressure on the battery life of your laptop.

As you may have already expected, you can’t pick which tabs to put to sleep. The system automatically recognizes the inactive tabs and takes action based on your browser settings.

The reverse is also possible. For example, if you want a tab to never go to sleep, you can whitelist it.

How to Enable Sleeping Tabs
