I have a Dell XPS 15 specifically for the screen size as I live in spreadsheets. You're right that the battery life is not the best, however I bought an Aukey 60W USB-C charger and the XPS15 appears to work just fine with it, at least at home; it even charged the battery, which I did not expect. Flying at the end of this week, so will give it a go on the flight to see if it still works OK.
But we should be having to deal with this problem in this day and age.
