A web search would have revealed to you that others have also observed this phenomenon. <http://www.linuxquestions.ORG/questions/linux-kernel-70/linux-kernel-3-0-battery-life-power-consumption-896637/> The power regression occurred in one of the 2.6.38 versions, presumably after the version you were previously using. <http://www.phoronix.COM/scan.php?page=news_item&px=OTM3NQ> Why the kernel development team have not fixed the issue by now, is anybody's guess, unless it is fixed in 3.1.
