Webpages were a combination of simple 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.--"
