Overview

• At $799, the iPhone 17 adds a larger 6.3-inch display with 120Hz ProMotion and always‑on, the new 18MP Center Stage front camera, doubled base storage to 256GB, and the same screen as the 17 Pro.
• iPhone Air debuts Apple’s C1X modem, which Apple claims is up to 2x faster than C1 with about 30% lower energy use, but it is limited to sub‑6GHz 5G and pairs with a thinner 5.6mm design that trades off a single rear camera, mono earpiece, USB 2 speeds, and slower wired charging.
• iPhone 17 Pro and Pro Max move to an aluminum unibody with Ceramic Shield 2 on both sides, add a vapor chamber for sustained performance, and feature A19 Pro, an upgraded telephoto with up to 8x ‘Fusion Zoom,’ the N1 chip for Wi‑Fi 7/Bluetooth 6, and storage up to 2TB.
• Preliminary Geekbench results point to modest CPU gains but large GPU improvements, with the 17 Pro Max posting the highest Metal score reported so far.
• Network support differs by model: the 17 and Pro phones use mmWave‑capable Qualcomm modems, whereas the Air’s in‑house C1X is sub‑6 only, and independent testing of Apple’s prior C1 showed performance can vary by carrier.
• Pre‑orders open September 12, with first‑wave availability on September 19.
