Google Chrome 86 may significantly improve battery life

06 July 2020 1

Google Chrome is a popular and yes so familiar browser despite a very big issue which is battery consumption. Although the state has been considerably improved over time, it still bothers in many ways. Google may be looking into ways to cut down on certain things or introduce some criteria that could prove helpful in retaining the battery life of a system. One such effort has come into notice, thanks to sleuths over at TheWindowsClub (TWC).

According to the site, Google is shipping a new experimental feature probably with Chrome 86 that would limit non-essential JavaScript timers in the background in order to save the battery from draining too fast. For instance, there is no need to track some things in the background, like checking if the scroll position is changed. Such non-essential JavaScript tasks in the background result in battery consumption. So, Google is throttling such timers in the background to offer more power to the users. This way the battery life will improve and the users will be able to stick more to their laptops without having to charge them too frequently.

Reportedly, this new feature is coming to Google Chrome for Windows, Mac, Linux, Android, and ChromeOS.

TWC claims it has seen a technical document that shows Google is doing an experiment to limit Javascript timer wake-ups in the background webpages to 1 wake up per minute. TWC points out that this feature is something similar to what Safari browser offers already. In this experiment, Google opened 36 random tabs in the background and one blank foreground tab to test it in extreme conditions. Google did this twice, one with and the other without throttling JavaScript timer wake ups to 1 per minute and found out that the latter one extends the battery life by almost 2 hours (28 percent).

In one more test, instead of a blank tab in the foreground, Google played a YouTube video in fullscreen mode. Before the start of the second test, Google also disabled ‘Energy Save’ settings to prevent the display from going idle. Furthermore, Google also disabled the ‘Automatically adjust brightness’ option in Display settings. This test further increased battery life by almost 36 minutes (13 percent). In this case, Google wanted to test if reducing the background activities proves helpful in extending the battery life even when there is a foreground activity.

Now, Google developers will implement this feature using a couple of ways to finally reduce battery consumption.
