Me too HP Victus 16 d0xxx
The computer lasts 2 hours maximum running on "Balanced" power mode, with "Battery Saver" enabled, with my nVidia RTX disabled via Device Manager, and Aeroplane mode enabled!!! 
All I'm doing is programming and using the browser.

I feel as though there is a major hardware issue in this model, or there's blatant false advertising.

This notebook has never lasted more than 3 hours on battery, not even when new. We would be lucky to be able to watch a 2 hour movie, when new, now cannot even do that 😞
