I always have the line height set to the minimum. I frequently read with kepubs. It is very rare that I see that problem. And almost all the times it is with the Charis SIL font or a derivative. Fonts that I am pretty sure have their font metrics deliberately set to give a smaller line height than they strictly should. To me, that is a bug in the font.

A Reader uses power to change screen pages. With ePub having more text on screen then KePub, you have less page turns with ePub. Less page turns equals less battery usage.
But then, the more characters on the screen, the longer it will take to render the page. Hence, more CPU and more battery usage. So there is a change that reading with a large font will actually use less battery.

That depends if ligatures and hyphens are turned on. If I do read KePub, I have ligatures and hyphens on.

I agree that the difference in the amount of page turns between ePub and KePub is not a big deal. I mentioned it in attempts to be more complete.
And how much difference do you think it will actually make? I'll credit maybe 1%. I won't give you 10%. It just isn't going to really matter. It is is a ridiculous point.
