Eye-and-I same ting!
Just waiting 2 more days for case and screen protector to arrive. Skin is here wondering if I should go naked+skin+screen protector until my first AC+ claim?
No you guys don’t and I’ll mention why.
1. 3 Camera’s of the Pro would take up considerably expensive internal real-estate that would affect:
FaceID (size and placement would affect the FaceID modules).
2. Of all the biggest complaints of the iPhone 12 mini being small battery and fixed with an ever so slightly larger capacity battery + much more efficient A15 in the 13 mini … that battery would drop in capacity and size significantly in the 13 mini Pro you propose/wish for it would just not even run up to 4hrs on full charge.
3. Now add ProRes recording:
The 13 mini has 512GB of storage max! 1 min of ProRes at 60 fps is 6GB … do the math with less battery than the 12 mini

4. You’ll be complaining about battery life as you use the touch screen so often that the 120hz screen would be so often at that level again battery drain!
5. Weight - those huge camera’s would increase the weight significantly what would be the point to have a small device that weighs like the Pro models? And you’d want stainless steel for the chassis?! Nope.
Of the last 20yrs of smartphones or longer that I’ve witness only 1 company has EVER come close or surpassed what Apple did with the 12/13 mini and that friends was …
Sony!
Xperia Compact lineup lasted 4-5yrs in total, 1 year even going as so stupidly to cancel water/dust resistance that that decision alone reduced sales so significantly they reversed that just the very next year. It’s been about 4yrs since the Compact line was made by Sony. Ever year the Compact had just about the same specs as the top of the line Xperia except for: battery capacity and display resolution/tech/refresh rate. Camera was the same as the top end for about 3yrs and that stopped.
Ever notice during the 12 mini’s announcement Apple chose to use the 007 music even though they re-enacted the 3GS scene of Mission Impossible? The 007 theme was a tongue-in-cheek poke towards Sony as Sony has all the rights to the 007 movies
you like the idea of a Pro mini iphone but you really do NOT want one for all the reasons you dislike the current iPhone mini in the first place.
