I understand that Apple did not make enough money to make it worth their while to continue the iphone mini line. However, it does seem like there is a profitable business for someone there given how beloved it was/is.
I only traded out my iphone 12 mini just recently for an iphone 16 pro (likely the last apple product I will ever buy but thats another story) and aside from the camera it is basically the same. Just heavier, awkward to hold and slightly worse designed.
No major player wants a smaller screen because it has downstream impacts on the pipeline of addictive material and ad pixels they can stuff into ocular nerves.
Phone screen sizes grew as the applications that could use screen space grew in demand.
People are watching 1080p films on the train now. The people who want smaller screens are usually willing to deal with a larger one. People who want larger screens usually cant operate their use cases on a smaller screen. Larger screens also tend to mask larger case meaning less miniaturisation required for the components.
You have people who want them unusably large and people who want them to fit in your hand. The solution in every other market is that products are manufactured to fit both sets of needs. You don't see pants coming in one size with the advice "wear a belt".
What's going on?
Great example. Because people who are shorter than average tend to have to get pants taken up, and people who are vastly taller than average tend to go to specialty stores.
The average height of pants is largely dictated by what the market will permit, requiring people to make adjustments or leave the market. Having a 2d matrix of height and width defined pant sizes is too complex for the market to bother with.
Technology is worse, anything that requires tooling is done the least number of times possible. While small phone enjoyers are disadvantaged, they arent disadvantaged enough to force them out of the market. Larger tooling is easier to make and caters to all other preferences.
