Chrome still has a reputation as a battery hog, particularly if you tend to open lots of tabs, however Google appears poised to repair that. TheWindowsClub understands that an experimental feature in Chrome 86 will reduce energy use by shutting down unneeded JavaScript timers and trackers when a tab remains in the background, such as those that check your scrolling position. The savings might be considerable in the right scenarios. Supposedly, Google saved two hours of battery life in a test with 36 background tabs and one blank foreground tab– severe conditions, to be sure, however not far-fetched.
The gains werent rather as significant when playing a YouTube video, but the more extensive test still included about 36 minutes of runtime.
