    OK, I gave it a try.

    Now my machine is reliably achieving over 4hrs (sometimes by a few minutes, LOL) of battery life according to battery report, while it sometimes dropped lower than that before. Not much of an improvement, honestly - but then again my laptop does run something all the time, always on VPN eats about an hour of battery life, and so on.

    Most services seem useful. )'=
    Edge is a crappy browser; wanted to use it for Youtube only but it's terrible, stops showing videos after sleep - and unsuitable as main browser due to lack of privacy features. Movies&TV can't do volume boost, unusable for watching most movies.
    Done.
    Done.
    Done, though mildly.
    Done.
    My CPU was entering deeper CPU states even without the tricks.
    Skipped.

    Done.
    Mine is fine, skipped.
    Don't usually attach anything to my laptop.
    Skipped - will replace with higher capacity someday, anyway.
    Can't live without mine, skipped.

    Common sense will work pretty well against viruses.

    Common sense doesn't work against misclicks.

    Thanks for this post, easy to follow, thoroughly explained; however, I don't achieve the C0% <1% on all core/threads, I always have my first 4 core/threads fluctuating to 14, 10, 6, etc., as such I am unable to sit under <0.5W consistently. I tried running with the park policy @ 16% and 0%, nothing seemed to work. But overall pretty happy, my max wattage on idle was 1.4W if I am not mistaken.

    I updated the Samsung NVMe Drivers.

    The 8750H is pretty powerful... It should idle very easily. I got my friends' 7700HQ down to 0.3W on idle CONSISTENTLY; The 8750H is basically the 8700HQ so I'm not sure what's happening there.

    Samsung NVMe drivers increase power usage, so if you want better power try default MSFT driver.

    Interesting, I use the Samsung drivers and it seems like I still get good results. I don't want to risk messing with swapping around for testing though.

    Does Fast Boot have any effect on battery life? Would it be better to disable it?

    I am finding conflicting information on line.
