I always felt the issue with removable batteries was they had a smaller capacity and would run out of life faster - so the need to be able to replace a battery if you wanted your phone to last more than a few years was important.

Now, with much higher capacity batteries that work better and are more efficient at handling all the demanding displays, high end gpu's and now AI tasks running the background? There's really no need to have removable batteries any more.

Sure, you're going to get a few lemons here and there, but for the most part, batteries these days have no problem lasting the 4-5 years that you need them. You still see three or four year old iphones on ebay with 80-85% battery being sold like hot cakes.
