I've moved on from the iPhone XR to the iPhone 12 mini. It's given me first-gen Moto X vibes. I love this phone size. Considering the iPhone 13 mini just in case there is no iPhone 14 mini. It may be time to retire my Moto Z4 and sell it and all of the Moto Mods. :(
Not sure what my next...
The last "small" phone I used as a daily-driver was the original Motorola Moto X. Went "large" with the third gen Moto X Pure Edition, Moto Z Force Droid, Moto Z2 Play, iPhone Xr, and Moto Z4.
Now I have an iPhone 12 mini which is such a great size.
