Weibo leaker Ice Universe revised the anticipated iPhone 18 Professional Max thickness at the moment, dropping the determine from 8.8mm to eight.75mm and matching it precisely to the iPhone 17 Professional Max. The change, reported by AppleInsider at the moment, got here with no rationalization. Separate claims a few battery within the 5,100–5,200 mAh vary, from Digital Chat Station, and a weight exceeding 240 grams, from On the spot Digital, weren’t revised and stay open questions, per Trusted Reviews.
The 6.9-inch show footprint is anticipated to remain unchanged, per Trusted Opinions. Whether or not the telephone positive factors something significant inside that unchanged shell is the more durable query, and the present proof does not reply it.
How the “thicker Professional Max” narrative constructed up
The thickness leak was the center chapter of an extended rumor thread. Final November, Weibo leaker On the spot Digital claimed the iPhone 18 Professional Max can be barely thicker than its predecessor and will weigh over 240 grams, doubtlessly making it the heaviest iPhone because the iPhone 14 Professional Max, MacRumors reported three months in the past.
Ice Universe added a selected quantity three months in the past: 8.8mm, up from 8.75mm on the iPhone 17 Professional Max. MacRumors described Ice Universe as an “oft-accurate” leaker, and the determine unfold shortly because the working expectation for the machine. Digital Chat Station then equipped a rationale: a battery within the 5,100–5,200 mAh vary, up from the 5,088 mAh cell within the eSIM model of the iPhone 17 Professional Max, Trusted Opinions reported three months in the past. The MacRumors Show tied it collectively in early April: a barely thicker chassis, an even bigger battery, a heavier telephone.
The boldness was already softening earlier than at the moment. Two months in the past, MacRumors noted that any thickness improve could be too small to indicate up on bodily dummy models, a quiet sign the 8.8mm determine was underneath strain heading into June.
What modified within the iPhone 18 Professional Max thickness leak and what did not
The distinction between 8.8mm and eight.75mm is 0.05mm. No hand or pocket comparability would register it. The revision issues for a unique motive: the identical supply modified a selected quantity with no said rationale, whereas the battery and weight claims that fashioned the remainder of the image stay untouched.
Ice Universe’s up to date determine appeared at the moment with no rationalization for the change, AppleInsider reported. Provide-chain leaks do not include changelogs. Whether or not the revision displays a unique manufacturing pattern, a shift in measurement methodology, or up to date specs from additional down the availability chain is unknown.
The battery estimate from Digital Chat Station remains to be 5,100–5,200 mAh, in comparison with 5,088 mAh within the present mannequin, per Trusted Opinions. That is a claimed improve of as much as roughly 112 mAh inside a chassis now rumored to be similar in thickness to its predecessor. Battery chemistry enhancements can yield modest capability positive factors with out added quantity, so the pairing is not unimaginable, however nothing within the present proof confirms it.
The burden declare, over 240 grams from On the spot Digital, can be unrevised, in line with MacRumors and Trusted Opinions. Each figures had been initially a part of the identical case for a thicker chassis. The thickness modified; they did not.
iPhone 18 Professional Max vs iPhone 17 Professional Max: what’s truly totally different on the surface
Primarily based on present leaks, not a lot. The 6.9-inch show footprint stays the identical, per Trusted Opinions, and the revised 8.75mm thickness matches the iPhone 17 Professional Max precisely. For context, the iPhone 16 Professional Max measured 8.25mm, in line with AppleInsider, that means the Professional Max line has already stepped up in thickness throughout latest generations.
The extra substantive modifications are anticipated to be inside. The iPhone 18 Professional lineup is reported to incorporate a smaller Dynamic Island, Apple’s in-house C2 modem, a simplified Digicam Management system, and a principal digicam with variable aperture, per the MacRumors Present. Every of these modifications consumes engineering assets with out altering the telephone’s outer dimensions.
In the identical publish that revised the thickness determine, Ice Universe claimed Apple directed its “consideration and vitality” towards the iPhone Extremely this cycle, AppleInsider reported at the moment. It is a believable rationalization for a static Professional Max chassis, but it surely comes from the identical uncorroborated publish because the revised thickness quantity, and no unbiased supply has confirmed it.
What the battery and weight claims imply for consumers
The hole between the 2 thickness figures was by no means going to have an effect on anybody’s shopping for determination. The hole between a significant battery improve and an unchanged one is a unique matter.
A telephone that positive factors 100-plus mAh of capability inside an similar shell, if the Digital Chat Station estimate holds, represents an actual enchancment for customers who already discover the Professional Max satisfactory in measurement. If that declare fades together with the unique thickness argument that supported it, the image modifications. A tool that matches its predecessor in thickness, show measurement, and weight, with no confirmed capability improve, is a upkeep launch from a {hardware} standpoint. The digicam, modem, and Dynamic Island modifications would nonetheless matter to consumers upgrading from older fashions, however anybody on an iPhone 17 Professional Max would have restricted {hardware} causes to maneuver.
The burden rumor complicates issues additional. A tool which will exceed 240 grams, doubtlessly the heaviest iPhone because the iPhone 14 Professional Max, per Trusted Opinions, mixed with a battery improve of round 100 mAh, raises a good query: the place is the additional weight coming from? The present rumors do not reply that, and no supply within the out there information presents an evidence.
The place the open questions sit now
The thickness quantity that dominated iPhone 18 Professional Max protection for the previous three months has been walked again by the one who set it, with no rationalization provided. The brand new 8.75mm determine deserves the identical skepticism because the 8.8mm declare it changed.
The battery estimate of 5,100–5,200 mAh and the burden declare exceeding 240 grams are the extra consequential unknowns, per Trusted Opinions. They’ve remained static by way of a number of rounds of revision from different sources, which is both an indication of reliability or just the absence of up to date data.
The alerts value watching: regulatory filings confirming precise battery capability, dummy unit measurements from case producers because the launch window approaches, and unbiased corroboration on the battery and weight figures from sources apart from Ice Universe. The iPhone 18 Professional Max and iPhone 18 Professional are anticipated to launch later this yr as a part of Apple’s annual refresh, per Trusted Opinions. Till extra concrete information arrives, the sincere learn is a telephone that hasn’t modified the place you possibly can see it, with the modifications beneath the floor nonetheless to be confirmed.
