Those replaceable batteries were also much lower power (in terms of capacity and max current) than the batteries of today. My iPhone today has roughly the equivalent of an 18650, compared to the Razr I had 15 years ago, which has roughly the equivalent of a AA.
For sure, I would love it if my phone had replaceable batteries. I carry a couple 18650s and 16340s in my backpack for my flashlights. But there are a ton of downsides to having them, particularly in a smartphone.
