The only way for it to make sense is with a set of standardised test loads.

Yes but no one uses the laptop like that. So how is it helpful? :)

Like fuel economy figures on cars, they'll never match actual usage but at least give you a point of comparison.

Thats why you cant rely on those either. These approximations are way off. Even more for laptops that can be used in so many ways. At least cars depend on roads and rules on the roads. Laptops also have tiny batteries that degrade very fast. So not reliable at all.

There are ways to measure battery capacity - en.wikipedia.org/wiki/Electric…

But for an avarage user all we care about is how long the battery lasts, which can vary depending on how efficiently the laptop and the processor utilizes its power. So yeah, its more complicated than just measuring battery capacity. But I'm sure there are ways to measure these things too, like if I let my laptop calculate the digits of pi for an hour to measure the battery drain and compare it with other laptops 🤷

Yup, totally, that was my experience all along.. I never got the declared battery life time at least once. That's why I never expected a great mobility from a laptop and mostly use it plugged in, basically using the battery as a fallback when power outage happen or need to move it to other place in the room without turning the computer off. Though manufacturers can't stop to feed you with high numbers, that's fo sho..
