According to the "leaker" ShrimpApplePro, known for his often proven predictions, the iPhone 15 Pro of the next school year will benefit from even thinner curved edges around the screen, compared to those of the iPhone 14 Pro. The appearance of these new models will thus be reminiscent of that of the Apple Watch Series 7 and 8.
Apple iPhone 15/15 Plus with thin edges too
Note that the screen as a whole will remain flat, and only the edges will be slightly curved. Curved glass is also expected to make an appearance on the cheaper iPhone 15 and 15 Plus models, but the edge won't be thinner compared to their predecessors. The “leaker” adds that the four iPhone 15s will have the same sizes as the iPhone 14 batch.
