iPhone 18 Pro Max: Full specs (variable-aperture camera exclusive)

The iPhone 18 Pro Max is the larger of Apple's two Pro flagships, expected to launch in September 2026. It has a 6.9-inch OLED display, the same A20 Pro chip as the smaller iPhone 18 Pro, and the only variable-aperture main camera in any 2026 iPhone.

This is the first year Apple has split the Pro camera system between the Pro and the Pro Max. If you want the best iPhone camera, the Pro Max is the obvious pick. The smaller Pro still gets the A20 Pro chip, 12GB of RAM, and 8K video, but the variable-aperture lens is exclusive to the Max.

What is different about the iPhone 18 Pro Max vs the iPhone 18 Pro?

There are four meaningful differences:

Variable-aperture main camera (Pro Max only). The Pro uses a fixed f/1.4 lens; the Pro Max adds moving aperture blades that switch between f/1.4 and f/2.8.
6.9-inch display (Pro Max) vs 6.3-inch (Pro). The Pro Max is the larger device.
Larger battery (~4,676 mAh vs ~3,800 mAh in the Pro). The Pro Max gets noticeably longer battery life.
$200 higher starting price ($1,199 Pro Max vs $1,099 Pro, both for 256GB).

Otherwise, the two devices share the same A20 Pro chip, 12GB of RAM, 48MP ultrawide, 5x telephoto, 24MP front camera, Apple C2 modem, and the smaller Dynamic Island.

What chip does the iPhone 18 Pro Max use?

The iPhone 18 Pro Max uses the A20 Pro chip, the same as the smaller Pro. It is manufactured on TSMC 2nm process.

Process: 2nm (TSMC N2) — Rumored, Nikkei
CPU: 6-core (2P + 4E) — Confirmed, same as A19 Pro
GPU: 7-core — Confirmed, same as Pro
Neural Engine: 16-core, 38 TOPS — Rumored
RAM: 12GB LPDDR5X — Rumored, supply chain
Storage: 256GB / 512GB / 1TB — Confirmed (pattern)

What about the display?

The iPhone 18 Pro Max has a 6.9-inch OLED display, the same size as the iPhone 17 Pro Max. It uses the same ProMotion 120Hz adaptive refresh rate, the same 2,500 nits peak outdoor brightness, and the same smaller Dynamic Island as the Pro.

What is special about the variable-aperture camera?

The iPhone 18 Pro Max is the only 2026 iPhone to feature a variable-aperture main camera. The lens can physically switch between f/1.4 (low light) and f/2.8 (daylight), with intermediate stops in between.

The variable aperture gives photographers control over depth of field and exposure that was previously impossible on an iPhone. In real-world use:

Daylight landscapes at f/2.8 to get more of the scene in focus
Astrophotography at f/2.8 to avoid star trails during long exposures
Portrait photography at f/1.4 for the traditional shallow depth of field
Sunstar effects at f/2.8 for more dramatic lighting

The lens module is supplied by Largan Precision, and Apple is reportedly only able to source enough modules for 35-40% of total Pro Max demand in the first production wave. Expect Pro Max supply to be constrained in the first 4-6 weeks of sale.

What are the full camera specs?

Main: 48MP, f/1.4 to f/2.8 variable aperture, sensor-shift OIS — Rumored, multiple sources

iPhone 18 Pro Max 256GB (2 years later): $540-$660

The 1TB Pro Max retains value best (the variable-aperture camera drives collector demand), typically 5-8% more than the 256GB.

What is in the box?

The iPhone 18 Pro Max device

The iPhone 18 Pro Max is the right pick for users on iPhone 15 Pro Max or older who want the best iPhone camera. For iPhone 17 Pro Max users, the variable-aperture camera is the main reason to upgrade.

Final verdict on the iPhone 18 Pro Max

The iPhone 18 Pro Max is the most premium iPhone Apple has ever made (excluding the iPhone Fold). It is the only iPhone in 2026 with the variable-aperture main camera, the longest battery life of any non-fold iPhone, and the largest display in the iPhone lineup. The $1,199 starting price matches the iPhone 17 Pro Max, so the upgrades come at no extra cost.

If you have an iPhone 15 Pro Max or older, the iPhone 18 Pro Max is the obvious upgrade. If you have an iPhone 16 Pro Max, the variable-aperture camera is a meaningful reason to upgrade. If you have an iPhone 17 Pro Max, the upgrade is incremental — the variable aperture is the main draw, but it is a specialized tool.
