Apple releases iPhone 18 as teardowns reveal camera and shipping designs

Retail debut and camera engineering

Retail sales for the iPhone 18 series began on September 18, 2026, drawing customer queues at Apple flagship locations such as the Fifth Avenue store in Manhattan. Buyers cited artificial intelligence additions and camera hardware as the primary reasons for upgrading. Teardowns conducted by repair specialists at iFixit examined the mechanical complexity of the main camera module on Pro models. Apple integrated an adjustable variable-aperture iris within the same physical footprint as the iPhone 17 Pro camera. The mechanism uses six overlapping magnetically controlled polymer composite blades, each matching the thickness of a human hair. Due to tight tolerances and adhesive seals, servicing individual components is unfeasible, requiring a full module replacement if damaged. Official parts for the 18 lineup have not yet been released, while camera assemblies for the iPhone 17 Pro cost 249 dollars.

“Very few repair enthusiasts on this planet will have the tools, techniques, or knowledge to get this variable aperture mechanism apart in a way that allows it to go back together.”

Shipping firmware and structural durability

To comply with international transport rules that cap single-cell batteries at 20 watt-hours, Apple deployed a firmware restriction that limits battery capacity before delivery. When a buyer powers on the device for the first time, the system automatically removes the lock. The handset then operates at its rated 21.75 watt-hours on US eSIM-only models and 21.06 watt-hours on European editions with a physical SIM tray. Users preparing devices for repair or resale can restore the limitation through a Prepare to Ship setting, which temporarily caps charging at 80 percent for 14 days and may cause the phone to discharge and warm up during configuration.

Durability testing by JerryRigEverything showed that Apple replaced titanium with aluminum on the Pro frame. The chassis withstood manual bend tests without fracturing, unlike the foldable iPhone Duo. Thermal management was also modified, adding cooling channels to eliminate internal heat hotspots during heavy workloads.

Display design and Face ID compatibility

Display adjustments on the Pro line also affected third-party accessories. To decrease the Dynamic Island cutout size, Apple placed the Face ID infrared camera underneath the display glass, leaving the dot projector and flood illuminator in the upper notch. Technical testing revealed that matte and privacy screen protectors block the infrared light, disabling facial recognition. Clear protectors remain unaffected, and accessory manufacturer Belkin verified that its protectors function with the sensor. The front screen features Ceramic Shield 2 glass, which Apple states provides three times more scratch resistance than the iPhone 16 Pro. Apple updated its support page to advise users to remove privacy covers if recognition fails.

Legal settlement over Siri AI marketing

In parallel with the retail release, Apple opened claims for a 250 million dollar class action settlement over the marketing of Siri Apple Intelligence features. The lawsuit followed a September 2024 promotional campaign starring actor Bella Ramsey that showed contextual personal data features not present at launch. Apple removed the advertisement in May 2025 and later deployed the delayed capabilities in iOS 27 on September 14, 2026.

The settlement covers United States consumers who purchased an iPhone 15 Pro, iPhone 15 Pro Max, or any iPhone 16 model between June 10, 2024, and March 29, 2025. Eligible claimants may receive between 25 and 95 dollars per device, with submissions closing on December 21, 2026.
