Gurman disclosed this information in his latest Power On newsletter. The journalist stated that this year's iPhone generation will offer four screen sizes, mirroring the lineup. This means customers can anticipate 6.1-inch, 6.7-inch, 6.1-inch, and 6.7-inch displays to arrive later this year. However, Gurman previously hinted that the iPhone 15 Pro Max might be named the iPhone 15 Ultra.

Dynamic Island is a pill-shaped area at the top of the iPhone screen, replacing the notch on previous iPhone models. Supported by software, Dynamic Island transforms into different shapes and sizes when users touch it to view notifications, sports scores, or control music. Display analyst Ross Young had previously declared that Dynamic Island would be present on all four iPhone 15 models, and this rumor has now been substantiated by Gurman.
As per the predictions of many, all four iPhone 15 models are expected to come with USB-C ports instead of Lightning. USB-C is a more widely adopted charging standard and offers faster data transfer speeds than Lightning. Gurman also corroborates the rumors that the iPhone 15 Pro models will feature a titanium frame with haptic volume buttons. Instead of physical movement, two new Taptic tools inside the device will replicate the sensation of pressed buttons, akin to the Home button on the 2022 iPhones and the trackpad on recent MacBook models.
