Good test. It does show that OLED on these ultrabooks may look nice, but they drag the battery life down and end up being well behind the IPS panels. I saw that with the Galaxy Book4 Edge, which was very disappointing, with 5-6 hours of SOT using a mixed workflow like yours. Also, these were on 60Hz, and my testing indicates a 10-15% loss of battery on my SP11 testing on 120Hz versus 60Hz, and that is probably why the default was 60Hz. So, I recommend the Dell XPS 13 non-OLED X Elite or the Surface Laptop 7 if you want game-changing Windows battery life.
