The screen of the iPhone Air, from which the iPhone 20 may borrow design elementsThe iPhone 20 will have larger displays than the current Pro and Pro Max models, with a leaker insisting 6.4-inch and 7-inch screens are being prototyped. The Pro models of iPhone have long played host to the largest screens in Apple's iPhone empire. According to a Tuesday Weibo post by serial leaker Digital Chat Station, Apple is prototyping two new screen sizes. The leaker says that one, measuring 6.4 inches, is probably going to be used on the anniversary iPhone 20 Pro. This is presumably for the iPhone 20 Pro Max, a larger alternative that follows the same Pro iPhone pattern.
