Why is it that laptop batteries have stayed at the same capacity (as in hours per discharge) for the past couple of decades, at least as far as I can see? Typically they seem to last for a maximum of six hours (give or take an hour or two), depending on what you're doing with the laptop, and it just seems a little strange that even though today's laptops are *massively* more powerful than the laptops of the mid 90s, the battery life hasn't been extended (or if it has, then not nearly as much as you might expect). A laptop that had a battery life of twenty four hours would be great, and such a good battery capacity would be a big selling point, I'm sure.
Apologies if I'm missing something obvious, such as maybe today's batteries are much more powerful than the batteries that powered 1990s laptops, but this is negated by today's laptops needing much more power from their batteries (but even so, I'd have thought today's batteries would be powerful enough to take this extra power demand in their stride, and still last a lot longer than older batteries?).
