Currently running this on my XPS 13. Works beautifully and honestly battery life is insane. _Much_ better even than just 19.04. It's easily on par with my 2015 MBP. I'm getting almost a week out of a charge using it for a few hours a day running just Chrome, PyCharm, and Signal most of the time.

I think I am doing something seriously wrong then. My 2015 XPS 13 only lasts a couple of hours.

with laptops, it really pays to make sure your kernel as recent as possible

try to put powertop --auto-tune into /etc/rc.local (before 'exit 0'!)

4 years is long enough for lithium batteries to decline pretty noticeably.

Yup, my xps 15 battery of that same vintage had to be replaced at the beginning of the year (under warranty).

Sorry, the MBP was my old work computer. I don't have it anymore. I was referring to its battery performance at the time.

I think the big differentiator is power top actually. When I upgraded to 19.10, I was prompted to check the differences between the old/new versions of the power top config file. The new version had a few more comments and was clearly updated, so I used the new config file during the upgrade process and went through all the options to make sure they made sense for my laptop.

Are we the same person? I could have written the exact same post. And was going to. Agreed about battery life while running Chrome and Signal a few hours a day.
