Rumored — not yet announced. Apple has not confirmed Apple iPhone 18 Pro Max or any specification on this page. Everything below is drawn from leaker and analyst reporting, cited to its original source in our news coverage. Last updated 2026-08-26; this page will be rebuilt with confirmed specs once Apple officially announces the device.
Apple iPhone 18 Pro Max
Expected to announce September 2026 (expected — unconfirmed as of publication) · Expected release September 2026 (expected — unconfirmed as of publication)
What's rumored so far
Apple's largest, most expensive iPhone is rumored to widen the gap with the standard Pro more than any recent generation: a possible camera-sensor exclusive (Apple's first variable-aperture main camera), a notably bigger battery, a 2TB storage option for the first time, and a heavier, thicker body — reportedly up to roughly 240g by one estimate. Both Pro models are expected to keep an aluminum frame this generation, per the most recent reporting — an earlier titanium claim has since been superseded. None of this is confirmed; Apple has not announced this device.
The Pro Max's battery capacity is the least settled number on this page — three separate leaks (a Chinese regulatory filing, a Weibo post, and Tom's Guide's own tracking) give three different figures, from roughly 5,088mAh to 5,567mAh. All agree on the direction (bigger gap over the standard Pro than usual) but not the exact number. The camera-sensor exclusivity claim is also explicitly flagged by MacRumors itself as ambiguous, not confirmed — the leaked files may simply not have covered the smaller Pro's camera section.

Camera
Main
48MP, Sony IMX905 sensor with variable aperture (rumored)A newer, more detailed MacRumors report (Aug 18, 2026) names this sensor specifically in the Pro Max's section of a leaked internal file — while the standard Pro isn't mentioned in that section at all. MacRumors itself calls this ambiguous rather than a confirmed Pro Max exclusive.
Ultrawide / Telephoto

WMCM (Wafer-level Multi-Chip Module) — rumored
Performance gain
15–18% faster than A19 Pro (leakers disagree on the exact figure)
RAM
12GB rumored baseline; one report suggests up to 16GBNot confirmed
Battery
Capacity
5,088–5,567mAh depending on sourceThree different figures from three different leak types (regulatory filing, Weibo post, outlet tracking) — genuinely unresolved, not a typo. All sources agree the Pro Max is getting a noticeably bigger battery-life gap over the standard Pro than in recent years.
Design
Chassis
Aluminum (rumored)Same aluminum-over-titanium correction as the standard Pro — see that page's note for the full sourcing timeline
Weight
Up to ~240g by one estimate (rumored)Would make it one of the heaviest iPhones Apple has shipped — tied to the larger battery and reportedly thicker body
Capture Button
Upgraded with gesture input support (rumored)
Ports
USB 4 Gen 3 (rumored)
Colors
Dark Cherry, Light Blue, Black, SilverSourced to physical dummy units (Sonny Dickson, May 2026)

NR-NTN 5G satellite data (rumored)Depends on Globalstar network upgrades outside Apple's control
Storage
Base tier
256GB (rumored unchanged)Sourced to TrendForce
Top tier
2TB, a new option (rumored)Multiple reports agree the Pro Max gains a 2TB tier for the first time, sitting above the existing 256GB/512GB/1TB options — this part of the story is fairly consistent across outlets
