iPhone 13 mini iPhone 13 Mini Pixel Rendering

[MICHAELSD]

I’m curious: since iPhone 13 Mini utilizes a resolution with a 476ppi resolution, is it rendering iOS at a point higher than the rest of the iPhone 13 lineup?

458ppi is a 3x point resolution based on the pixel density of the original iPhone which iOS is based off of, which is what iPhone 13/Pro/Pro Max use. I.e. 326ppi or Retina utilized a 2x point resolution.

iPhone 6/7/8 Plus utilized a 3x point 458ppi resolution to render at 401ppi.

So is iPhone 13 Mini rendering at a 4x resolution then downscaling, or natively at 476ppi? It looks like the latter, which Apple didn’t do on the Plus-sized phones for simplicity.

It also is incredible the lengths the design team went to making the Mini-sized phone the best it can be, since a sharper resolution is more beneficial on a smaller display—and there is still a noticeable difference IMO.

The minis use 3x as their scale factor.

A 1080×2340 pixel screen would suggest a new resolution of 360×780 points, but the iPhone 12 mini actually shows a scaled down iPhone 11 Pro resolution of 375×812 points. This means that the iPhone 12 mini does not introduce a new resolution. However, since the actual physical screen in pixels is not an integer multiple of the resolution in points there will always be some scaling artefacts. With a 3x screen they will hopefully be difficult to see. The status bar is 6 points taller than the iPhone 11 Pro. The bottom bar is the same height.
