Overview

  • Apple is expected to unveil four iPhone 17 models in mid-September 2025: a standard version, an ultra-slim Air variant, a Pro and a Pro Max.
  • Insider leaks suggest an industrial design overhaul with a skinnier Air chassis and Pro backs featuring a hybrid part-aluminum, part-glass frame instead of titanium.
  • A first-for-iPhone vapor chamber cooling system is rumored for the Pro and Pro Max to improve thermal performance under the next-generation A19 Pro chip.
  • Both the standard iPhone 17 and iPhone 17 Pro are tipped to adopt 6.3-inch LTPO displays with 120 Hz refresh rates, while the Air aims for a 6.6-inch screen within a 5–6 mm body.
  • Apple is reportedly testing new purple and green shades for the base model and a sky blue finish for the Pro lineup, expanding beyond last year’s pastel palette.
