There are six overlapping blades inside the new iPhone 18 Pro’s main camera. Each is about the width of a human hair. Together they open and close to control how much light reaches the sensor. It is a beautiful piece of engineering. It is also, according to iFixit’s teardown, almost impossible to repair at the blade level.
Apple’s own repair manual makes the consequence plain. The aperture is not an orderable part. The lens containing it is not an orderable part. Apple offers one replacement item: “Camera.” The whole assembly is the smallest supported repair.
That is the line Apple’s repair progress still refuses to cross. The company has made the phone easier to open and its modules easier to remove. When one microscopic mechanism fails, though, the customer still pays at module scale.
A gorgeous mechanism with a built-in bill
The iPhone 18 Pro’s 48 megapixel main camera carries the first variable aperture in an iPhone. The concept is not new. Samsung shipped one in the Galaxy S9 in 2018. Apple’s version uses a magnetically operated iris made of six polymer composite blades. Fitting that mechanism inside a phone camera is extraordinary materials engineering.
The repair story is less impressive. iFixit scored the phone 7 out of 10, matching last year’s iPhone 17 Pro, and cited camera and battery assemblies that are easy to remove. The teardown team was reluctant to declare a blade repair literally impossible. In practice, it came close. WIRED reports that iFixit called the job “almost impossible.”
Adrian Kingsley-Hughes, writing about the teardown for ZDNET, explains the likely failure path. Dirt, dust, and moisture can gum up a mechanism this small. A cracked lens cover can admit those contaminants, after which touching the aperture will almost certainly require a replacement camera module. ZDNET put a replacement lens cover at about $10 and the iPhone 17 Pro camera assembly at $249. Apple had not posted a Self Service Repair price for the new assembly when the teardown appeared.
The repair bill depends on how much hardware Apple makes you replace at once. A cheap piece of glass can expose a tiny mechanism, and a failure in that mechanism can turn into a full camera purchase. Making the assembly easy to lift out does not make that outcome affordable.
A 7/10 that measures the wrong thing
This phone earned a good teardown score for real reasons. The battery is secured with screws once the glued display is removed. The camera assembly lifts out. The cooling system improved. Apple is getting better at physical access, and pretending otherwise would weaken the argument.
Physical access is only one part of repairability. Price, parts availability, software support, and the size of the smallest replaceable unit decide whether a repair happens or the phone becomes waste. A score focused on disassembly can praise an easy module swap while missing the cost imposed by the module itself.
US PIRG uses a wider test. Its 2026 report combines European repair indexes with American factors such as parts pricing and corporate lobbying. It gave the iPhone a D minus in April, the worst phone grade in the report and down from C minus in 2025. Nathan Proctor, the group’s senior right to repair director, put the problem cleanly: “Why are we grading on a curve? We should just have longer-lasting products.”
The 7 out of 10 and the D minus can both be honest. One says a technician can reach the camera. The other asks whether the owner has a fair chance of keeping the device alive.
Every concession came after the bill
Apple’s concessions have a paper trail, and legislation appears on nearly every page.
Oregon passed SB 1596 in 2024, the first state law to ban parts pairing. That practice uses software checks to restrict a replacement component or some of its features. The law applies to devices sold in 2025 and later. Apple opposed it. John Perry, then Apple’s principal secure repair architect, testified that the restriction would “undermine the security, safety, and privacy of Oregonians” by forcing manufacturers to accept parts of unknown origin.
Weeks after Oregon’s governor signed the bill, Apple announced support for used genuine parts. Its Self Service Repair program had been announced in 2021 and launched in 2022. Apple also backed California’s 2023 repair bill after pressing for disclosure requirements around used and nongenuine parts. Four state laws came to cover nearly 70 million people.
The concessions are meaningful. Apple’s current support page says the iPhone 18 Pro accepts used Apple cameras, and that most third party parts will continue to operate unless a security or privacy function is involved. That is a better policy than the old wall of warnings and disabled features.
It also proves pressure works. Lawmakers forced open a repair system Apple had spent years defending. Yet the new aperture exposes what those victories have not solved. Apple’s 2026 manual still lists the entire camera as the orderable part. There is no aperture, lens, or iris assembly in the catalog. Owners gained more freedom to install a module, while Apple kept the power to define how large that module must be.
Security does not require replacing the whole camera
Parts pairing helps deter theft and protects biometric hardware. There is also a real engineering case for module level repairs. They can preserve alignment, water resistance, and image quality in a camera built to microscopic tolerances. A loose blade sold in a plastic bag would be useless to almost everyone.
Those concerns explain why a loose blade is not a useful repair part. They do not explain why Apple’s catalog stops at the complete camera. The official manual does not discuss a lens and aperture subassembly or explain why one cannot be serviced. It jumps from three screws and three cables straight to a complete camera.
That choice pushes the cost of integration onto the owner after Apple has collected the sale. It also turns working material into waste around every failed subcomponent. A phone in this price class should be repairable after cracked glass, contamination, tired batteries, and years of ordinary use without treating a whole assembly as the atomic unit of repair.
Apple has shown that it can move. Screw secured batteries, used camera support, public manuals, and fewer software penalties are all progress. The record also shows what made the company move: laws with deadlines. The iPhone 18 Pro’s unfixable eye is the next repair barrier those laws should target. Getting inside the phone is no longer enough. Owners need the right to replace the part that actually broke.
