We used the latest browser versions available: Edge (Build 14955 from the Insider Preview), Google Chrome 56 (dev channel), Firefox 52, and Opera 41 (Beta).Īs for device, we used a Microsoft Surface Book. 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. If you are on a Windows laptop, you might want to shut your Chrome and use Firefox or Internet Explorer in case you need to conserve juice. This essentially shows how the browsers are able to save power while downloading data packages and rendering video. 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.
That’s because websites change almost every time you look at them: Ads change, images change, scripts change, articles change. 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.
