All I'm saying is that you used to be able to get smartphones that were like this, and they weren't any more expensive than any other smartphones. (EDIT: I was wrong, they were about $25 more expensive.)

So this is demonstrably possible. The only reason I can think of that it's not done anymore is cost savings.

Modern phones are packed to the brim with features. My phone has a goddamn LIDAR scanner! I really don’t think it is feasible anymore, and I think most people would prefer an extra 2-300 mAh over swappable battery. Of course replacing it once by a dedicated shop each 3 years should be possible.
