Whereas Apple does a fabulous job of weaving a narrative round a brand new product, it’s not till we get a teardown that we actually get to see the literal nuts and bolts. And it simply occurs {that a} hot-off-the-production-line iPhone 18 Professional has landed within the arms of the very best teardown consultants on the planet — the parents over at iFixit.
Additionally: How lengthy must you maintain your cellphone for?
And as soon as once more, it’s a combined bag of tech wonderment and new restore complications.
Variable aperture brings new complications
The primary little bit of wonderment I used to be thinking about seeing the way it ticked was the brand new variable-aperture lens. Having taken aside lenses for movie, DSLR, and mirrorless cameras — with a mix of success and failure — I knew that this could be extremely small.
And small is what now we have right here.
Additionally: I’ve used each iPhone 18 Professional fashions – right here’s how my shopping for recommendation is altering in 2026
The iris consists of six tiny overlapping magnetically operated “polymer composite” leaf-like blades which can be the identical thickness as a human hair.
And simply as with huge lenses, the most important enemy of this kind of mechanism goes to be filth, mud, and moisture. And due to its small dimension and tight tolerances, it’s extremely susceptible to being gummed up.
The iFixit crew, relatively optimistically, says they’re “reluctant to name a restore unimaginable,” however I’m right here to inform you that touching it will virtually definitely require a brand new digicam module.
Through the years, I’ve changed quite a lot of digicam lens covers on iPhones, and an issue I foresee is that this kind of harm will let filth, mud, schmoo, and different contaminants get on the delicate elements, inflicting additional harm.
Additionally: Declare as much as $95 in the present day from Apple’s Siri AI settlement – right here’s how
Break a lens cowl — which I can purchase for about $10 — and also you’ll be changing the entire lens meeting. And whereas Apple hasn’t but launched elements for the iPhone 18, a non-aperture digicam meeting for the 17 Professional is $249.
Changing the battery is straightforward – as soon as the show is out
Take excellent care of your new iPhone, and inside just a few years, you’ll nonetheless be changing the battery. And it’s at all times been a bit hit-and-miss whether or not a brand new iPhone launch makes battery repairs simpler or more durable.
The iPhone 18 Professional/Professional Max is each.
The unhealthy information is that with a purpose to substitute the battery, you’ll need to undergo the entrance. And meaning there’s an actual threat of damaging the show or tearing a ribbon cable. I, together with just about each repairer I’ve talked to, would like to not need to take away a show as a result of a small chip or hidden crack can develop into a giant, apparent crack, and folks then begin pointing fingers.
In the event you’re going to do this restore, you’ll want warmth (iFixit mentioned they heated the iPhone at 158°F/70°C for quarter-hour after which at 162°F/72°C for an additional 10 minutes, which is lots), copious quantities of isopropyl alcohol to melt the adhesive, and quite a lot of endurance.
And presumably a brand new show.

As soon as the display is off, the battery is held in a steel tray and secured with 13 tiny screws, simply because it was in final yr’s iPhone. That is the simple bit, so in the event you keep away from breaking the show and mangling the show body an excessive amount of, it’s downhill from there.
Higher cooling, nevertheless it makes information restoration more durable
As chipset speeds and total efficiency enhance, so does the quantity of warmth that must be dissipated. And that warmth wants to depart the iPhone with out inflicting the particular person holding it to panic.
For the iPhone 18 Professional and Professional Max, Apple has taken the cooling current in final yr’s {hardware} and made it bigger. The vapor chamber is thrice bigger and covers virtually all the again of the iPhone, a transfer that enables extra warmth to be shifted with out creating uncomfortable — and presumably alarming — hotspots.

However each upside has a draw back. Right here, the draw back is that reaching the circuit board requires digging by way of a number of layers. Whereas not many individuals might want to do circuit-board-level surgical procedure, it’s the kind of factor that information restoration specialists might want to do.
General repairability
iFixit has given the iPhone 18 Professional/Professional Max a repairability rating of seven out of 10. It’s a disgrace that each restore begins with taking out the show. Regardless of how skilled you might be, there’s an opportunity of a breakage, and at a minimal, that’ll add $150 to $200 to the restore price.
Apart from that, Apple has clearly put quite a lot of effort into the cooling and beefed it as much as not solely accommodate extra warmth but in addition dissipate it higher with out creating hotspots.
