If Apple made a pro model phone in a mini size, I'd totally buy it. I don't need a large phone, that's why I get all the features I want in a regular size of the 14 pro. If they made the 14 pro and all it's features in a mini size, it would be even better because of the convenience of the small size. Battery life would be sacrificed I bet, but you'd have all the bells and whistles.
Believe me, Apple is not able to make such a product, it no longer has the capacity (all systems are set for huge screens and huge batteries), it no longer wants it (the times of miniaturization and good design are over, this is the time of nonsense and economic returns), it would not know to whom to sell it and it does not even want to sell it.
I bought an SE 2016 on the first day, I changed 7 in 2 years, all with the same problem with the Home button or the screen, all NOT REMEDY with a defect, as soon as the cpu started to heat the rear glass it lifts up.
The same happens with Macs (in fact there is no longer a small one), with iPads (the mini of problems sw has many because Apple does not invest money in it), with Apple Watches (which now have the smallest version of the size of a large one).
Miniaturization costs, if you want to make it powerful, it costs exponentially more. Apple produces Chinese waste and sells it at prices tenfold than the value, which at least a long time ago was tied to software that was worth something, now it sucks.
You wouldn't want a small and powerful Apple product, trust me, you would throw it Against his face every 5 minutes.
