I've been carrying a 2013 ThinkPad X1 Carbon for a few years now, running whatever version of Ubuntu is current at the time.

Overall it's been a great machine; most everything Just Works™, and in the rare cases where something doesn't the large community of Linux-using ThinkPad owners has made it easy to find out how to fix it.

There is one absolutely glaring exception to this, though: power management. For reasons I've never been able to figure out, and despite what feels like endless tinkering with power management settings, I've never been able to get more than 2 hours and change out of a full battery charge, which is (IMO) unacceptable.

Now that it's getting on three years old I've been thinking about replacing it, and the natural thing to do would be to buy the newest X1. But I'm worried that I'm just going to end up with another machine that's constantly needing to be tethered to the wall again.
