Internal documents circulated to German mobile operators indicate that Apple intends to unveil the iPhone 17 family at a press event on Tuesday, 9 September 2025. The date matches the company’s long-standing preference for early-September launches and aligns with forecasts made by Bloomberg’s Mark Gurman. The carrier guidance says pre-orders are scheduled to open on Friday, 12 September, with first deliveries and in-store availability set for Friday, 19 September in major markets including the United States, Europe, China and Japan. According to the same material, Apple plans four handsets this cycle: the baseline iPhone 17, the higher-spec iPhone 17 Pro and 17 Pro Max, and a new ultra-slim “iPhone 17 Air” that effectively replaces the Plus variant dropped last year. Separate leaks this week show a 2.49 mm-thick battery module said to belong to the iPhone 17 Air—roughly half the thickness of the unit reportedly headed for the 17 Pro. While the slimmer cell is believed to hold about 2,800–2,900 mAh, Apple is expected to offset the reduction with a more efficient A19 Pro processor, 12 GB of RAM and faster 50-watt wireless charging.
