I have always rejected the idea of an XR/11 sized iPhone, because it is not confortable for one handed usage (and on the store, every time I've tried an XR/11, I've dropped onto the table). HOWEVER, if they manage to make the XR/11 design smaller, even a bit, I might be interested. A 5.8" design like the iPhone X could be a good choice.
The ideal form factor for me is the iPhone 13 mini, and I've been able to test one this holidays, a truly amazing device, but sadly enough, I will return it because using it outside my home is very uncomfortable, having to type the passcode again and again due to Face ID not working with face masks. It is a pity that the only solution Apple offers to you is to pair it with an Apple Watch, a device I am not interested into, to be able to use the device properly on a pandemic situation. Face ID is not recognising me with a mask, and that's a major flaw that I cannot afford on a device that would be intended to last many years (and yes, masks are here to stay, the waves of SARS-CoV-2 haven't stopped yet and there's no point in the current horizon to when this will end). So I am staying with Touch ID.
Apple hasn't released the iPhone 13 mini with Touch ID, and next year's iPhone 14 will be big phones, regardless of them having under display Touch ID or not, I'm not gonna buy a smartphone I cannot handle with one hand (this is, bigger than 5.8"). Maybe the 2024 iPhone SE will feature the iPhone X/XS/11Pro body, but until then, this year I'm gonna return the 13 mini and get an 2022 iPhone SE, with an outdated design but hopefully a bigger battery and slightly better cameras.
