I'm very happy with the battery life of my XPS 9360 running Ubuntu (17.10 currently). I get a full working day out of it. So far (about six months) I've received some number of firmware updates (3-6?) through fwupd. These are integrated well into Ubuntu and the Linux ecosystem generally. The updates happen through UEFI and no other OS is required in order to receive them. I believe Dell prepare the updates for this pipeline themselves. Disclosure: I work for Canonical and use the laptop for work. But my choice of laptop, and money to buy it, is my own (it isn't a business expense; my contract merely requires me to have and maintain my own laptop).
