Very high power demand after upgrading to 18.04

I upgraded to Ubuntu 18.04 (from 17.10) yesterday and am currently still running the Unity desktop (same problem in Gnome desktop though).
My problem: I now have a power demand that is about 100% higher than before (around 15W vs. 8W before) without any apparent reason.
As I'm working from my laptop this means that I only get about half the battery life and since the CPU is also heating up quicker my fan is running constantly. I haven't found a quick way to measure the power while plugged in but the CPU heats up just as fast which leads me to believe that the power consumption is high as well.
This is true even when there is no demanding process:

Any idea why the power demand went up this much?
It's driving me crazy that I can't figure out where the problem is. At the current state this makes my laptop (1300€, 5 months old) basically useless as I rely on battery power even for work.
Please help me :)

There were some kernel changes that had a dramatic effect on idle power consumption for big server systems with on the order of 100 CPUs. Not so much, but still measurable, for smaller systems. A long shot, but worth a try on your computer. Try kernel 4.17-rc7. Oh, and try enabling your watchdog.

Thanks for the advice. I played around a bit and at least found the location (if not the reason) for the problem: Apparently the NVIDIA driver or anything that gets installed along the way makes a problem in 18.04. After installing this driver (instead of Nouveau driver) the power demand is basically doubled, no matter if switched to performance (MX150) or power saving (Intel 620 GPU). Even after switching back to Nouveau and removing everything from NVIDIA, the problem still persists. That leads me to believe that something else was installed alongside and is causing the problem.

This is not a solution suggestion, but, just in case if you want to measure the current power consumption, here is a small script that will put an indicator in the Unity's task bar: askubuntu.com/a/1024771/566421

There were some kernel changes that had a dramatic effect on idle power consumption for big server systems with on the order of 100 CPUs. Not so much, but still measurable, for smaller systems. A long shot, but worth a try on your computer. Try kernel 4.17-rc7. Oh, and try enabling your watchdog.

Thanks for the advice. I played around a bit and at least found the location (if not the reason) for the problem: Apparently the NVIDIA driver or anything that gets installed along the way makes a problem in 18.04. After installing this driver (instead of Nouveau driver) the power demand is basically doubled, no matter if switched to performance (MX150) or power saving (Intel 620 GPU). Even after switching back to Nouveau and removing everything from NVIDIA, the problem still persists. That leads me to believe that something else was installed alongside and is causing the problem.

This is not a solution suggestion, but, just in case if you want to measure the current power consumption, here is a small script that will put an indicator in the Unity's task bar: askubuntu.com/a/1024771/566421
