Tab sleep timers in Microsoft Edge stop inactive web pages from draining your computer memory by putting them to sleep after a set period of time. By default, Microsoft Edge puts idle tabs to sleep after 5 minutes of inactivity.
Changing this timer lets you keep tabs open longer without losing your place, or puts them to sleep faster to save laptop battery and speed up your PC.
Open Microsoft Edge Settings, navigate to System and performance, then Performance. Ensure “Automatically put tabs to sleep” is on and select your desired inactivity time from the “Put inactive tabs to sleep after” dropdown. This adjustment helps manage your computer’s resources.

Adjusting Your Tabs’ Sleep Time
Adjusting this duration lets your laptop battery last longer or keeps heavy web apps ready for instant switching. This setting controls the edge tab sleep duration, helping your browser run smoother, especially when you have many tabs open.
- Open Microsoft Edge Settings
First, open Microsoft Edge. Click on the three dots in the top-right corner. This is the “Settings and more” button. Then, click on Settings in the menu that appears.
- Go to System and Performance
In the Settings window, look at the left-hand side. Click on System and performance.
- Find the Sleeping Tabs Options
Under the "System and performance" section, find the category called Performance. Click on it.
Scroll down until you see the "Sleeping tabs" section. You will see a switch labeled Automatically put tabs to sleep. Make sure this switch is turned On. If it is off, your tabs will never go to sleep, and you cannot change the time. - Set Your Desired Inactivity Time
Right below the "Automatically put tabs to sleep" switch, you will see another option: Put inactive tabs to sleep after. Click on the box next to it. A list of times will show up, like 30 minutes, 1 hour, or 2 hours. Choose the time that works best for you.
Warning: If you choose a very short time and then find yourself waiting for tabs to reload often, try setting the time longer. Find the time that works best for how you use the internet.- Shorter times (like 30 minutes or 1 hour): These are good if you open many tabs and want to save power quickly. This is especially helpful if your computer is older or you run many programs at once.
- Longer times (like 1.5 hours or 2 hours): These are better if you switch between many tabs often and want them to be ready right away.
