I think that's PWM dimming vs DC dimming.

PWM dimming turns pixels on and off to make them darker. So for 50% of the brightness, it's off 50% of the time. Higher end panels flicker much faster which helps mitigate perceived flicker. I think 500hz and above is preferred.

For DC dimming is just using voltage to control the darkness with no flickering involved.

I have a 7840U with a 55HWr battery. I can squeeze out 7 hours. If I'm power using then 5-6 is typical. With the 63WHr battery, you'll get about 15% more time with it.
