New Google Chrome will increase laptop battery life

Chrome is probably the most commonly used web browser on all platforms, but this is not because it is an ideal browser. Although it has improved significantly over the years, especially in the area of memory management, Chrome is still notorious for severely draining battery life, which Microsoft Edge (which preceded the Chromium version) tried to capitalize on. This drawback may soon be a thing of the past if the latest Chrome update becomes a stable version – it can save users from 30 minutes to 2 hours of battery life even with dozens of tabs open.

The optimization planned by Google focuses on what is one of the quiet killers of the web browser: jаvascript timers. These timers work at intervals to check options such as page scrolling, ad analysis, writing to log files, etc. Although they may be important for the web pages you are currently viewing, timers do not make much sense for most pages that open in tabs other than the current one.

Google checked how much battery is saved if you set the jаvascript timer interval to turn on only once a minute. With 36 open background pages and one open blank page, the battery life was extended by almost 2 hours, which means a 28% increase. Of course, no one leaves a blank tab, and Google has run another test with playing YouTube videos, without saving power or darkening the screen. Battery life increased by half an hour or 13%, which is important for laptops.

Of course, this kind of optimization will have side effects, and some pages may not work properly if the jаvascript timers are configured in the above way. In this regard, Apple has found a successful solution for Safari – it is to apply this policy only after five minutes of inactivity in the background tabs. Google is reportedly planning to do the same.

If these changes are implemented, it will significantly improve Chrome's performance on all platforms. However, Google will allow system administrators to disable this feature for at least one year after it becomes available. This will allow them to test the function and make sure that nothing is broken or make the necessary changes to become compatible with the new policy.
