I have the same specs. I just disabled the MX150 with Bumblebee/bbswitch (am running Kubuntu dual boot with Win 10). It's fine now I am getting same battery time as windows. I'm a linux newbie so it took me a while to source out the procedure from the internet. I'm typing this on windows where I don't have the links...you can get the instructions if you google it. 

 

Oh, I would also suggest to install TLP for power management and Powertop for monitoring.

 

Sorry hope that helps a little.

This works great on my T480, tried it with Ubuntu 18,04, mint 19 and Kubuntu.

It seems that I have solved
NVIDIA X Server Settings was installed during installation.
Following your advice and what I read on the web I set up as Intel Prime Profiles instead of NVIDIA profiles. restarted. Today it has lasted much longer
in the coming days I try with new tests working normally connected in wifi and not wired and after I update you

ciao
