A new feature update coming to Chrome 86 looks set to make serious reductions in its resource usage. The experimental feature could extend battery life considerably on laptops by shutting down certain background tasks in open tabs.

Google’s Chrome browser is the most popular browser in the world with current figures showing it has a market share of 65 percent. That doesn’t mean it is perfect, however, with users often complaining about it being a resource hog. Things could be set to change with an incoming feature update to Chrome 86 that should reduce CPU cycles that are otherwise offering little in terms of functionality to the end user.

According to the folks at TheWindowsClub, the experimental feature being introduced to Chrome 86 will limit Javascript timer wake ups in background webpages/open tabs to 1 wake up per minute. This is similar to a feature already built into Apple’s Safari browser and will be available in all versions of Chrome 86 across Android, Chrome OS, Mac, Linux and Windows. Currently, the number of wake up calls in Chrome’s Javascript times doesn’t offer any benefit to users.

According to Google’s internal testing, switching to just one Javascript timer wake up per minute with 36 random tabs open in the background yielded a massive 28 percent improvement in laptop battery life when the foreground tab is about:blank. With foreground activity like running YouTube in fullscreen mode along with some other tweaks, the same reduction in Javscript calls resulted in a 13 percent improvement in battery life. Google hasn’t confirmed if it will take the feature mainstream, but even with it enabled, Safari still leads it in efficiency by some margin according to Google’s own data.

I have been writing about consumer technology over the past ten years, previously with the former MacNN and Electronista, and now Notebookcheck since 2017. My first computer was an Apple ][c and this sparked a passion for Apple, but also technology in general. In the past decade, I’ve become increasingly platform agnostic and love to get my hands on and explore as much technology as I can get my hand on. Whether it is Windows, Mac, iOS, Android, Linux, Nintendo, Xbox, or PlayStation, each has plenty to offer and has given me great joy exploring them all. I was drawn to writing about tech because I love learning about the latest devices and also sharing whatever insights my experience can bring to the site and its readership.
