I guess I never really tested it out. The only thing I can tell you is that I currently have 82% battery and it says I have 4 hours and 40 minutes left. I know that's far from an exact time, but that's really what I get my times from. I can tell you that I forgot I lowered my CPU% peak on battery to 30% and I still have no hiccups with anything I do. I also rarely go above 20% brightness. Not sure if any of this helps you...I tried these exact same settings. still cannot get past 4.5 hrs.... is ur 6 hr based on predicted or actual usage time? ive been timing my self whenever im on the sp, and I cant get past 4:30 hrs..
any specific tips would b appreciated. thnc
