Very different experience with a X1 3rd generation (Broadwell). Battery life is 10h+, touchpad is butter smooth (to my surprise, better under Linux than with the original Windows 8.1), fans are stopped most of the time and the laptop is very silent. All this with Debian stable (more recently testing), so a pretty conservative set-up.

For battery life (and maybe fan noise?), have you installed "laptop-mode" or its successor "tlp" (the laptop project)? Both will tune the system automatically for AC or battery power, and it does make a huge difference for battery life. If you don't use either, you should really try them: the 5 mn installation time will be a good investment ;)

Main issue on my side: I bought it just after it was announced, and Linux support was so-so (functional, but annoying glitches and stability problems). Next time, I'll wait for the new models to be out and will buy the last gen one on the cheap --- there's so little changes anyway nowadays. But now all this is gone, and Linux support is top notch.

Quality ok but not as good as I had imagined: there's now a bit of flex in one corner. Not a problem in practice, I just expected more sturdiness from a TP.
