Which would make me want the refresh rate to be user-configurable. I would not mind at all if the 1 Hz refresh rate caused parts of the page I don't care about, such as animated ads to stutter and become unwatchable. If given the choice between stuttering ads but longer battery life, or smoothly-animated ads with shorter battery life, I'd choose the unwatchable ads every time.

Ideally, I would be able to bind a keyboard shortcut to the refresh-rate switch, so that the software doesn't have to figure out that now I'm on Youtube so I actually want the higher refresh rate, but now I'm on a mostly-text page so I want the refresh rate to go back down to 1 Hz. If I can control that with a simple Fn+F11 combination or something, that would be the ideal situation.

Not that any laptop manufacturers are likely to see this comment... but you never know.
