The XPS 13 I've found is pretty easy on the battery. However, I did opt for the 1080p screen. My understanding is that the 4k screen (which would be unreadable to my 40 year old eyes in any case) uses significantly more power.

You know that higher resolution just means that the text is sharper, not that the font is smaller, right? :-D

This is still unfortunately not true on Linux.

Single-screen 2x scaling (about the easiest possible HiDPI option) seems to work okay, but then you're basically running 1080p, so why bother.
