Google is using Chrome’s new “tab freeze” feature, which will pause (freeze) tabs you don’t use. This means lower CPU usage, faster browsers, and longer laptop or convertible battery life.

Problem: Too Many Tabs Opened

If you always open only one tab, Chrome only needs to render one webpage at a time. But you may have more. Even if you don’t use them, every tab you open in Chrome contains an open web page. This page uses system memory. All scripts and other active content on it will also continue to run, which means that the web page can use CPU resources in the background.

In some ways, this is a good thing: even if you switch tabs, tabs can continue to play audio or update themselves in the background. When you switch back to it, you don’t need to wait for the web page to reload, it is instant.

But this may be bad. If you open a lot of tabs, or even only a few tabs with heavy web pages, they may consume a lot of system resources, take up your memory, take up CPU cycles, slow Chrome’s response speed and drain your resource battery. Therefore, Chrome engineers created the “discard tab” feature, and now they have created the “tab freeze” feature. They are related functions but will do different things in different situations.

How To Tag Freeze Saves Your Memory

A large number of tabs will open on Chrome's tab bar.

Tab Discarding was added as early as 2015. This is what Google calls the “memory saving” feature. In short, if your computer is low on memory, Chrome will automatically “discard” the content of the “uninteresting” label. If you interact with a tab, Chrome will not automatically discard it, but background tabs that you haven’t interacted with within a few hours are your main goal.

When the content of the tab is discarded, it is deleted from the system memory and the state is saved to disk. There is no change in the Chrome interface. The tab is displayed on the tab bar and looks normal. However, when you click on it and switch to it, you will see that Chrome takes a moment to quickly reload the page and bring you back to where you were.

This slight delay is why Chrome only discards tabs when the system’s memory is “running low”. It is best to use RAM for caching. But automatically discarding the tab and quickly reopening it is better than forcing Chrome users to manually add bookmarks and close the tab.

After discarding the tab, the process will actually disappear from Chrome’s built-in task manager, and you will no longer see the memory used by Chrome. When you click to reload it, it will start again.

How to Freeze Your Chrome To Saves Your CPU (and battery)

Tab freeze is different from tab drop. After the tab is frozen, its content will remain in the system’s memory. However, the content of the tab will be “frozen”. The web pages in the tabs will not be able to use the CPU or perform operations in the background. For example, suppose you open a heavy webpage in a tab somewhere, and that webpage is always running. After a period of time, Chrome will automatically “freeze” it and stop performing any operations until you interact with it again. These are the basics, and Google may explain how it works in more detail in the near future.

Label freeze is an experimental feature. It is built into the current stable version of Chrome 77, but it can only be started manually. In the upcoming Chrome Canary version of Chrome 79, Chrome can automatically freeze tabs, just as it can automatically discard them.

In Chrome Canary, if you go to chrome://flagsand search for “Tab Freeze”, you can freeze tabs with several tabs. When this option is enabled, Chrome will automatically freeze after displaying the “eligible” tabs in the background. 5 minutes. Depending on the option you choose, Chrome can freeze it or unfreeze it for ten seconds every fifteen minutes-enough time to synchronize with the server or to complete some work when needed. Google is clearly testing which option is the best.

Although the tab freeze is an experimental feature, it is almost certain that it will appear in the stable version of Chrome at least in some form soon. The options in Chrome Canary were discovered by TechDows.

How to play tab freeze (and discard) on Your Chrome

If you want to understand how they work, you can use the current stable version of the Chrome browser to use both features at the same time. Just type chrome://discardsdiscards in Chrome’s Omnibox and press Enter.

You will see a diagnostic page with a list of open tabs and whether they can be frozen or discarded. On the right side of the page, you will see action links to “Freeze” and “Abandon” for each tab.

You can test it to see the difference. For example, if you start YouTube and start playing a video, clicking “Freeze” on the tab will pause the video playback, but will not delete the content of the YouTube tab from the memory in the Task Manager. Conversely, clicking “Discard” will pause the video playback and delete the content of the tab from the memory-if you open Chrome’s Task Manager, the tab will disappear. Clicking “Load” will reload the contents of the tab into the memory.

Why discarding and freezing are so useful

In other words, if the system memory is full, Chrome will discard the tabs you don’t use to free up space. When you click on the tabs, it will reload them silently, but you will notice that the page loads instantaneously. When you have enough memory, Chrome does not need to give up tabs-Chrome will use memory as a cache instead of leaving it empty. This speeds up.

However, even if you have a lot of memory, Chrome will quickly look at the frozen tabs that you do not interact with to save CPU time and battery power, which may make Chrome and other applications on the system more responsive. It still keeps them in memory—this way, when you reactivate it by switching to a frozen tab, the web page in that tab is ready to be used as soon as possible.

If Chrome needs to free some memory, it may discard frozen tabs. But you can’t freeze a discarded tab: it has been deleted from memory and is not really open, so it can’t perform any operations in the background.

The upcoming version of Microsoft Edge will be based on Chromium, and Google’s work on Chrome will also make Windows 10’s default web browser better. It is expected that future versions of Edge will also automatically start to freeze tabs.
