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

Complete spec sheet for the iPhone 18 Pro Max — A20 Pro chip, 6.9-inch OLED display, 48MP variable-aperture main camera, 12GB RAM, Apple C2 modem.

Last updated: (2 weeks ago)By Priya Raman

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:

  1. 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.
  2. 6.9-inch display (Pro Max) vs 6.3-inch (Pro). The Pro Max is the larger device.
  3. Larger battery (~5,425 mAh eSIM / ~5,235 mAh physical SIM vs ~4,800 mAh expected in the Pro). The Pro Max gets noticeably longer battery life.
  4. $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.

  • Size: 6.9 inches — Confirmed, multiple sources
  • Resolution: 2796 x 1290 (expected) — Rumored
  • Refresh rate: 1Hz-120Hz adaptive (ProMotion) — Confirmed
  • Peak brightness: 2,500 nits outdoor, 1,600 nits HDR — Rumored
  • Dynamic Island: 35% smaller — Rumored, updated July 2026 from earlier 30% Ross Young estimate
  • Always-on display: Yes — Confirmed
  • Ceramic Shield 2: Yes — Confirmed

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
  • Ultrawide: 48MP, f/2.2 — Rumored
  • Telephoto: 12MP, 5x periscope, f/2.8 — Rumored
  • Front camera: 24MP, f/1.9, autofocus — Rumored
  • Video: 8K at 30fps, 4K at 120fps, ProRes 2 — Rumored

How much RAM and storage?

  • RAM: 12GB LPDDR5X — Rumored, supply chain
  • Storage: 256GB / 512GB / 1TB — Confirmed (pattern)

What modem and connectivity?

  • Modem: Apple C2 (custom) — Rumored, Bloomberg / Jeff Pu
  • 5G: Sub-6 GHz + mmWave — Rumored, new with C2
  • Wi-Fi: Wi-Fi 7 (802.11be) — Rumored
  • Bluetooth: 5.4 — Rumored

  • Satellite: Emergency SOS + limited satellite data — Rumored
  • NFC: Yes (Apple Pay) — Confirmed
  • Thunderbolt: USB-C with USB 4 / Thunderbolt 4 speeds — Confirmed, same as Pro

What about the battery and charging?

The iPhone 18 Pro Max has the largest battery in any iPhone to date (except the iPhone Fold, which has a dual-cell design). On July 2 2026, Macworld published a report based on social-media leaks that pins down the exact capacity: 5,425 mAh for the eSIM-only model and 5,235 mAh for the physical-SIM model. The report traces the data to a Tata Electronics leak cycle in late June 2026.

  • Battery capacity: 5,425 mAh (eSIM) / 5,235 mAh (physical SIM) — Leaked, Macworld / 9to5Mac (July 2 2026)
  • vs iPhone 17 Pro Max: +337 mAh (eSIM) / +412 mAh (physical) — gains of roughly 7-9%
  • Wired charging: 25W USB-C — Confirmed, same as Pro
  • Wireless charging: 25W MagSafe (with 30W adapter) — Confirmed
  • Reverse wireless charging: No — Confirmed

The new capacity pushes the Pro Max into new territory for iPhone battery life:

  • Video playback: 35-38 hours (vs 29 hours on iPhone 17 Pro Max)
  • Streaming video: 30-33 hours (vs 25 hours)
  • Audio playback: 120-130 hours (vs 95 hours)
  • Mixed daily use: 22-24 hours of screen-on time (vs 18-20 hours)
  • Standby time: 14-16 days

The 412 mAh bump on the physical-SIM model is larger than the 337 mAh bump on the eSIM model, because Apple freed up internal space previously used for the SIM tray in the eSIM version. Both variants use stacked-cell battery packaging — the same approach Apple used in the iPhone Fold.

What are the dimensions and weight?

  • Height: 163.0 mm — Rumored
  • Width: 77.5 mm — Rumored
  • Depth: 9.00 mm — Leaked, Ice Universe (July 9 2026), 0.75mm thicker than iPhone 17 Pro Max
  • Weight: 240 g — Leaked, Ice Universe (July 9 2026), 7g heavier than iPhone 17 Pro Max

The Pro Max is heavier and thicker than the iPhone 17 Pro Max for the first time since the iPhone 12 Pro Max generation. The increase is battery-driven: the 5,500 mAh cell (per Ice Universe, consistent with the 5,425-5,567 mAh range from Macworld and regulatory leaks) requires more internal volume than the iPhone 17 Pro Max's 5,088 mAh / 4,823 mAh cells, and Apple is not offsetting the change with lighter materials. Apple could still adjust the chassis before launch.

What materials is it made from?

  • Frame: Grade 5 titanium — Confirmed
  • Front: Ceramic Shield 2 — Confirmed
  • Back: Textured matte glass — Confirmed
  • IP rating: IP68 (6m for 30 min) — Confirmed

What colors will it be available in?

The iPhone 18 Pro Max shares the same color lineup as the iPhone 18 Pro:

  • Dark Cherry (new) — Rumored, The Information
  • Light Blue (new) — Rumored
  • Natural TitaniumConfirmed (carried over)
  • Black TitaniumConfirmed (carried over)

How much will it cost?

  • 256GB: $1,199 — Confirmed (pattern)
  • 512GB: $1,399 (+$200) — Confirmed
  • 1TB: $1,599 (+$400) — Confirmed

When will it launch?

The iPhone 18 Pro Max will launch at Apple September 2026 event, alongside the iPhone 18 Pro and the iPhone Fold.

  • Announcement: September 8, 2026 (expected) — Rumored
  • Pre-orders: September 11, 2026 — Rumored
  • Availability: September 18, 2026 — Rumored

Expect the Pro Max to sell out within hours of pre-orders opening, due to the constrained supply of the variable-aperture lens module.

How much will repairs cost?

Based on iPhone 17 Pro Max pricing:

  • Screen replacement (front): $379
  • Back glass replacement: $199
  • Battery replacement: $99
  • Camera module replacement (main): $549 (variable-aperture is more expensive)
  • Camera module replacement (ultrawide): $349
  • Camera module replacement (telephoto): $399
  • Other damage: $649 flat fee

AppleCare+ for iPhone 18 Pro Max is expected to be $14.99/month or $289 for 2 years.

What is the iPhone 18 Pro Max resale value?

Based on iPhone 17 Pro Max resale values, the iPhone 18 Pro Max should retain roughly 65-72% of its value after 12 months and 45-55% after 24 months. Specifically:

  • iPhone 18 Pro Max 256GB (1 year later): $770-$870
  • 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
  • USB-C to USB-C cable (1m, woven, USB 3.0 rated)
  • SIM ejector tool
  • Apple logo stickers
  • Documentation

No charger, no EarPods, no case.

Will my iPhone 17 Pro Max case fit the iPhone 18 Pro Max?

No. The iPhone 18 Pro Max is 9.00mm thick — 0.75mm thicker than the iPhone 17 Pro Max — and the camera bump is larger (to accommodate the variable-aperture module). iPhone 17 Pro Max cases will not fit the iPhone 18 Pro Max. The Dynamic Island is also smaller, with a different cutout size.

For MagSafe accessories, the MagSafe magnet ring is unchanged. All existing MagSafe chargers, wallets, and battery packs work with the iPhone 18 Pro Max.

What about environmental specs?

  • Recycled materials: 38% recycled cobalt in battery, 100% recycled tungsten in frame, 75% recycled aluminum in enclosure
  • Packaging: 100% fiber-based, no outer plastic wrap
  • Carbon footprint: 64 kg CO2e for the 256GB model (vs 70 kg for iPhone 17 Pro Max — 9% reduction)
  • Trade-in: Apple Trade In accepts older iPhones for credit toward the iPhone 18 Pro Max

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.
