You can simply look at the sale of battery packs and pocket size portable batteries. It is relatively large. > Because Apple doesn't think it is worth the trade offs and they know a thing or two about making well designed phones. That is a flawed way of thinking, apple is interested in optimising profits, not well designed phones, or at least not more than sales and revenue.
