My source tells me that Apple is skipping the X55 and X60 modems and is instead using the QC X65 5G modems in the iPhone 12 Pro models. They are integrating the chip into the notch, which will make the notch approximately 1.5 times larger than on the iPhone X, XS and 11 models. They’re also ditching the 5.4” model and the sizes will instead be 6.1”, 6.5”, 6.7” and 7.1”.
