I didn't do anything special.Years ago the xps15 had some issues installing linux, there was a git repo with a special post install script to get the drivers sorted. Dell fan control can be weird but this was many years ago at this point.
I have a normal ubuntu install, I use the i3wm to reduce general load. Resolution set to 1440p with xrandr, no scale adjustments.
GPU disabled, totally on intel graphics.
My xps is about 4.5 years old right now, I have replaced the battery when it started to swell slightly, the replacement was salvaged from another and even worse, so after a year I put the original battery back in.
I honestly think the biggest thing is a tiling wm. Any time I go from full gnome to i3wm, my battery life gets an instant 3 hour bonus.
Big ole note, because of the age and battery degradation, i can squeeze about 6-7 hours out of with if I limit myself to a single firefox window and text editors. When it was brand new, 13 hours of normal use was totally doable.
