I plan to get Haswell one and I was wondering if you could change from 60Hz to 40/30Hz and get more battery? My current HP laptot runs standartly at 40Hz and there's like 30 min battery from 40-60.

OSX doesn't have any way for you as the user to change the refresh rate. It is, what it is.

I don't think you'll increase the battery life so much that it would be worth it, but that's just my opinion
