You ignore that it’s physically impossible to put a flagship performance in an under 5 inch format.

Not even slightly.

The battery alone scales with size. The camera is a physically space occupying bunch of glass and sensors, that even the ultra size phones have to put them in awkward bulges outside the phone main body to deliver the kind of qualety demanded by users.

The obvious solution is to make the body of the phone very slightly thicker. Thinness is more important in a bigger phone to shave off some of the overall bulk and make it easier to hold but when the area of the phone is smaller, you can easily make it thicker, with the added advantage of making the camera bulge less ridiculous. I’m reluctant to even call it a tradeoff because you’re not really giving anything up. This would have been a legitimately comparable phone, but they never made it so there’s no direct sales comparison in the market. There is no hard data, only inferences.
