Power consumption - Matebook X Pro

Edit: Based on a suggestion in the comments, I Switched from Nvidia-390 driver to Nouveau and discharge rate went from ~10w to ~5w.
I have a core i7 Matebook X Pro.
It lasts about 6 hours on battery.
This is a fresh install of Budgie 18.04.
powertop shows: The battery reports a discharge rate of 10.6 W
This is with absolutely no other apps started (except Tilix terminal to run powertop).
I have other people telling me they average about 5W discharge rate.
I have installed the nvidia-390 drivers and the discharge rate is about the same whether I'm using Nvidia GPU or Intel integrated (620) graphics.
It almost seems as if somehow the Nvidia side is still enabled?
Any thoughts on what else I can do or what other info I can give to help diagnose?
Thanks,
Ken

It's entirely possible that NVIDIA settings is not actually powering down the NVIDIA card. Have you tried using the Nouveau driver instead? NVIDIA's linux driver is primarily focused at computation performance, not power consumption or dynamic mode setting like their Windows driver can do. The Nouveau driver has better power management, but does have lower performance for games.

I'll switch back and see what results I'm getting. I did notice that powertop was reporting: Power est. Usage Device name 7.92 W 99.0% Display backlight That is just for the backlight even when I have it at the very lowest level. That seems like a lot. I'm wondering if that isn't just for the backlight or if it is also the graphics card contributing.

Switched back to Nouveau and it dropped to ~ 5.5w. AND the Display backlight pretty much disappeared from the list. Brilliant. Thanks so much for the tip.
