Internet Explorer 9 is outgreening rival browsers, including Chrome 10, Firefox 4.0, Opera 11 and Safari 5 according to testes performed by Microsoft.
"For many customers, battery life is the most important gauge of power consumption. A typical laptop uses a 56 Watt hour battery, which means the laptop can consume 56 Watts worth of energy for one hour before running out," revealed Jason Weber, IE Performance Lead. The fewer Watts the browser consumes the longer the laptop battery will last.
Microsoft's green tests for browsers involved measuring power consumption in six scenarios, the first of which involved a machine running just Windows 7 as the baseline.
Weber noted that additional scenarios covered both HTML4 and HTML5 sites:
Browsers navigated to about:blank (power consumption of the browser UI).
Loading one of the world's most popular news Web sites (common HTML4 scenario).
- Running the HTML5 Galactic experience (representative of graphical HTML5 scenario).
- Fish swimming around the FishIE Tank (what test is complete without FishIE).
- A typical 56 Watt laptop running IE9 has a battery life of 3:45 hrs, the longest out of all browser, and outlasting the all browsers but by almost one hour, with the exception of Firefox 4.
Battery life was just 2:56 hrs with Chrome 10, 3:35 hrs with Firefox 4, 2:43 hrs with Opera 11 and 2:55 hrs with Safari 5.
