Hi All, I am using Windows 8.1 since it came. But I am seeing that battery life of my laptop in general is very less than that compared to Windows 8. Are you guys seeing similar issues? I saw that Windows 8.1 preview for Surface RT had some issues . But as what we have is supposed to be RTM , I was expecting it to have better or atleast same battery life. Can this issue be caused because I installed drivers for windows 8 ? But I don't think that those driver might be causing this issue.
