In our tests, the fluctuations resulted in a difference of 10-20 minutes between each battery life rundown. While surely not exactly a realistic use case (everyone uses the web differently), this methodology gives a decent impression of how quickly browsers drain battery power under extreme conditions and nonstop loading of websites. Simulating browsing: Due to the above-mentioned fluctuations when browsing the web, we’re using a script that opens up 10 popular websites, scrolls down to the end, closes them and opens them back up again after a break of 30 seconds. This test proved to be very reliable when repeated. This essentially shows how the browsers are able to save power while downloading data packages and rendering video.

FIREFOX OR OPERA FOR MAC MAC OS X
Video streaming: Just as Microsoft and the other browser makers, we’re testing battery life while binge-streaming Netflix Full HD content nonstop until the battery runs dry. We pick our favourites, including Safari, Edge, Chrome, Brave, Vivaldi and more. Mac OS X (Safari, Firefox, Chrome and Opera). It's one of the best browsers for Mac, just in case you're looking for a browser for your Apple device. However, Firefox picked up the pace at the end due to its superior security and privacy protections. Despite its built-in security and privacy features, Brave offers fast and responsive performance, proving quicker than Firefox and Vivaldi, two other options on this list. That’s because websites change almost every time you look at them: Ads change, images change, scripts change, articles change. Opera wins for its wide array of built-in tools, its ease of use and fast speed. It’s essentially impossible to really measure browser performance in any scientifically accurate way. Rather, let’s check this for ourselves and find out if Chrome battery life is better or worse than the competition’s. But let’s not get into mudslinging between browser-makers. Both Opera and Chrome have retaliated, trying to debunk Microsoft’s claims.
