To be honest, what the iPhone released in 2022 is called ultimately depends on what Apple calls the iPhone model introduced in 2021. If the 2021 iPhone model is marketed as the iPhone 13, then we expect the 2022 iPhone model to be the iPhone 14. On the flip side, if the iPhone model introduced in 2021 is the iPhone 12s, then we expect the 2022 iPhone model to be the iPhone 13. This, definitely, assumes that Apple doesn’t skip the number 13, given the bad luck it is associated with in many cultures.
The biggest change that we currently expect with the 2022 iPhone is the removal of the notch cutout. The notch design was first introduced with the iPhone X, and it has stayed the same since then. The notch is where Apple houses its sensors for things like Face ID.
Reliable Apple analyst Ming-Chi Kuo reports that Apple will drop the notch in 2022, starting with the high-end iPhone 14 Pro. Kuo describes the design change as a “punch-hole design.” This is similar to what’s currently used on many high-end iPhone designs.
As for the iPhone 15 series, the new display apparently runs at 240Hz, because of course it does. In-display Touch ID is included as is an always-on display component. That hole-punch hides a 40-megapixel camera, by the way.
