Apple is expected to unveil its entire iPhone 17 line-up on 9 September, according to internal launch schedules circulated to German mobile operators and reported by outlets including iPhone-Ticker, AppleInsider and 9to5Mac. The documents indicate pre-orders will open on 12 September, with first deliveries and in-store sales set for 19 September, matching Apple’s usual two-week rollout cadence. The line-up is tipped to comprise the iPhone 17, 17 Pro, 17 Pro Max and a new ultra-slim iPhone 17 Air that replaces the current Plus model. Separate leaks this week show a purported 2.49 mm-thick battery for the 17 Air—about half the thickness of the reported 17 Pro cell and rated at roughly 2,800–2,900 mAh—underscoring Apple’s push to make the handset its thinnest ever. The Pro devices are expected to feature Apple’s A19 Pro processor, revised camera modules and up to 12 GB of RAM. Apple has not confirmed the date, but a 9 September event would follow the company’s pattern of Tuesday launches in early September. The same briefing materials suggest Apple Watch Series 11 could share the stage at the Cupertino presentation.
