    What do you mean by display "hz"?

    For example 24Hz 50Hz 60Hz 75Hz, its the refresh rate of the display

    A couple years ago, I didn't see a major difference between the 50 and 60 Hz options on my then-daily driver ThinkPad T400. You'd probably get farther with underclocking and undervolting.

    My desktop monitor can display 50, 59 and 60 Hz.
    Difference betweem 50 and 60 is around 8%.
    I doubt will see an exact 8% improvment in battery life, let's say 2-4%, which is insignificant.
    But, if you also reduce brightness and ocntrast, underclock/undervolt the CPU/GPU and other intensive optimizations, maybe you can reach something like 10-15% battery life more.
    But, is it really worth it, such hassle for 20-50 more minutes (based on average 4-10 hours) ??
