Thanks for the numbers. I looked up some numbers too, and my laptop has a 74.5 Wh battery. Additionally, I'm using an 80% charge limit so ~60 Wh. Since I'm sure about the battery life in hours (as projected by powertop), system power must be 9 W or so. Now I also recall 11 W before some tuning.
For reference, a M2 16" macbook pro has a 99Wh battery, and Apple advertises 16-17 hours max battery life. That's 5.8-6.25W.
So, their estimate of 6W for the AMD flagship AI laptop is exactly in line with the Apple flagships.
