IE8 Beats Other Browsers In Laptop Battery Life 263

WARM3CH writes "AnandTech tested a laptop with an AMD CPU, a laptop with an Intel CPU, and a netbook to compare battery life while running Internet Explorer 8, Opera 10, Firefox 3.5, Safari 4, and Chrome. They tested on simple web pages and flash-infested ones. IE8 had the best battery life on both laptops (followed by FF + AdBlock), and Safari had the worst battery life. On the netbook, Chrome was slightly ahead of IE8. The report concludes: 'Overall, Internet Explorer and Firefox + AdBlock consistently place near the top, with Chrome following closely behind. Opera 10 Beta 3 didn't do as well as Opera 9.6.4, and in a couple quick tests, it doesn't appear that the final release of Opera 10 changes the situation at all. Opera in general — version 9 or 10 — looks like it doesn't do as well as the other major browsers. Safari is at the back, by a large margin, on all three test notebooks. We suspect that Safari 4 does better under OS X, however, so the poor Windows result probably won't matter to most Safari users.'"
