Watch if it changes in a day or so. A brand new Windows install runs all sorts of updates and
stuff in the background. It’s also going to make inconsistent estimates without much history of power use to factor in.
Brightness makes a big difference. Most battery tests are at like 150 nits. The framework can go a lot brighter than this and a lot of people actually like and use higher brightness. Unfortunately at 400 nits the screen starts consuming more power than the rest of the system, your battery life isn’t going to be great, and the efficiency differences between platforms is going to be less noticeable. Testing a full brightness would also punish laptops with brighter screens which is actually a nice feature to have, which is why most reviewers don’t test this way.
