Of all the battlefields we’ve witnessed in the browser wars, this one’s never really crossed our minds before: energy efficiency. Yes, the power efficiency of a piece of software, not hardware, is being touted by Microsoft as a differentiating feature for its fresh new Internet Explorer 9 . It’s thrown together the top five most popular browsers and put them through a cycle of benchmarks — including Microsoft’s own FishIE Tank graphics acceleration test, but not the somewhat popular Adobe Flash — while measuring how much power they use beyond what the underlying Windows 7 system needs to keep itself going. Shockingly, IE9 was the winner each and every time and there’s a tenuous conclusion drawn that if you want good battery life, you’ll be going with Internet Explorer. Oh well, whether you consider them a good laugh or really valuable buyer’s advice, there’s plenty more of these power consumption comparisons at the source link below. IE9 is the most energy-efficient modern browser, according to Microsoft’s own testing originally appeared on Engadget on Tue, 29 Mar 2011 19:38:00 EDT. Please see our terms for use of feeds .
