Zebook UX430UQ battery life

Anyone else owns aUX430UQ (the one with the Nvidia 940MX GPU)?The battery life (on Ubuntu) has been just ****ty. A year after I bought it, itlasts for only one hour of video conferencing + half an hour of browsing, OR 2hours max of browsing. The GPU is not in use (good luck getting Nvidia GPUs towork on Ubuntu 16). The fan spins up like crazy when the CPU usage goes above30% (try loading Chrome with 30+ tabs), while my old DELL E7450 loads Chromewith 200 tabs without spinning up the fans (CPU at 100%).Thermal management on this laptop is junk. Not sure if it's Ubuntu's fault(I've never run Windows on it).I'm thinking of replacing it with an ultraportable (I like the ~3lbs weight ofthe UX430) with integrated graphics, but I want to make sure the graphics cardcan power a 4K monitor.
