Edge Beats Chrome in Battery Test, Says Microsoft (zdnet.com)
The latest installment of Microsoft's browser battery challenge shows once again that Edge consumes less energy than Chrome and Firefox. From a report: With the Windows 10 April 2018 Update rolling out across the globe, Microsoft thinks it's once again time to square Edge up against Chrome and Firefox in a new battery-life test. Microsoft's browser experiment shows a time-lapse of "three identical devices, three different browsers, streaming one video." Firefox, Edge, and Chrome play what appears to be a Netflix video on three Surface Books. As usual, the Edge device lasts the longest, depleting the battery after 14 hours and 20 minutes. The Chrome device lasted 12 hours and 32 minutes, while the Firefox laptop ran out of steam after just seven hours and 15 minutes.
If it takes you 14 hours, 20 minutes to download Chrome or Firefox, you've got bigger problems. Microsoft really needs to work harder on its browser downloader.
When IE6 came out, I seem to recall MS publicly stating they were ceasing development of IE. Unsurprisingly, once Firefox came out and started decimating their market share, they started up again.
