- iPhone 18 Pro will measure roughly 2mm thicker than the iPhone 17 Pro, per Weibo leaker Fixed Focus Digital, with estimated total thickness of 9.9–10.9mm versus the current 8.75mm.
- iPhone 18 Pro Max camera plateau is expected to swell to 11.54mm, up from 11.23mm on the iPhone 17 Pro Max, based on April dummy models referenced in the piece.
- The added bulk reportedly accommodates the iPhone's first variable-aperture main camera, a module that reportedly costs Apple 50% more than the current fixed-aperture lens per May supply chain reporting.
- LG Innotek and Sunny Optical are ramping up production of the new variable-aperture module, the source says.
- Apple is keeping the aluminum alloy mid-frame introduced on the iPhone 17 Pro rather than returning to titanium, the leaker confirmed, while warning that new color options may face the same discoloration and chipping issues that have affected some iPhone 17 Pro units.
- iPhone 18 Pro, iPhone 18 Pro Max, and Apple's first foldable iPhone are all expected to launch this September.
Why it matters: Variable-aperture hardware is the headline camera upgrade of the cycle, but the new module costs Apple roughly 50% more per unit — a cost increase that is landing alongside already rumored iPhone 18 Pro price hikes and a foldable iPhone launching the same month, meaning buyers will pay more for a noticeably chunkier Pro this September.
