iPhone 18 Pro
2nm Chip King × Variable Aperture
A20 Pro debuts TSMC's 2nm process; the main camera gets a six-blade physical variable aperture for the first time, 60W wired fast charging, and Apple's in-house C2 modem — the biggest Pro upgrade in years. This article breaks it down across five technical dimensions and compares it head-to-head with the iPhone 17 Pro series.
Design & Appearance
Forged aluminum unibody, Ceramic Shield 2 front, four all-new colorways. The Dynamic Island shrinks by ~35%, pushing the screen-to-body ratio to 94.7%.
Two Sizes, Four Colors
The iPhone 18 Pro series keeps the forged aluminum unibody; the Ceramic Shield 2 front is 3× more scratch-resistant than the iPhone 16 Pro. Burgundy red is the hero color, Glacier Blue takes the fresh route, and classic Black and Silver return.
Dynamic Island Slimmed 35%
The new Dynamic Island shows up to three Live Activities at once; screen-to-body ratio rises to 94.7%, getting visually closer to a true full-screen.
Ceramic Shield 2
Front is 3× more scratch-resistant than the iPhone 16 Pro, with Ceramic Shield on the back too; IP68 water resistance (6m / 30 min).
2TB on 18 Pro for the First Time
The smaller model offers a 2TB storage tier for the first time; the Pro Max keeps 256GB–2TB in four steps — a boon for ProRes creators.
Camera Control Button
All-new Camera Control button: exposure, depth, zoom, styles and tone in one tap; the Action button is now customizable.
Performance — A20 Pro Chip King
First to launch on TSMC 2nm, packaging borrowed from the M-series chips, a 7-core GPU + dual 16-core NPU, cooled by a new VC vapor chamber.
The 2nm Era: A Leap in Performance & Efficiency
The A20 Pro is Apple's first 2nm smartphone chip — CPU performance up ~20% over the A19 Pro, GPU up ~40%. The dual 16-core Neural Engine doubles AI compute; paired with a new VC vapor chamber, heavy gaming holds full frame rates.

Camera — Variable Aperture Era
The 48MP Fusion main camera gets a six-blade physical variable aperture for the first time, ƒ/1.48–ƒ/4.0 in four steps, with ~50% more light in low-light scenes.
6-blade Variable Aperture, Total DOF Control
The main camera's six laser-cut blades form a variable-aperture system that adapts to light and depth automatically. ƒ/1.48 lets in ~50% more light for low-light shots, while ƒ/4.0 creates star-burst artistic effects. New Pro controls put aperture, shutter, white balance and histogram at your fingertips.
Pro Controls + Photographic Styles 3
The Camera app adds customizable Pro controls, pinning aperture, shutter speed, white balance and histogram. Photographic Styles 3 adds texture and grain adjustment to soften skin or create a film look. Smart Tracking focus locks the subject and stays sharp even after they leave and re-enter the frame.
Battery & Fast Charge
The longest battery life in iPhone history — 43 hours of video playback on the Pro Max. 60W wired fast charging hits 50% in 15 minutes.
Longest Battery Life in iPhone History
Thanks to the A20 Pro's 2nm efficiency, a new battery design and system optimizations, the iPhone 18 Pro Max plays video for up to 43 hours — 6 hours more than the 17 Pro Max. Wired fast charging jumps from 40W to 60W, reaching 50% in 15 minutes.

Fast Charge: Time to 50%
Display & Connectivity
Super Retina XDR display with 3000-nit outdoor peak brightness. Apple's in-house C2 cellular modem, WiFi 7 + Bluetooth 6, eSIM support.
Super Retina XDR · 3000 nits
6.3/6.9-inch Super Retina XDR OLED, 460 ppi, ProMotion 120Hz adaptive refresh, always-on display. Outdoor peak brightness hits 3000 nits. For connectivity, it's the first iPhone with Apple's in-house C2 cellular modem, replacing the Qualcomm baseband.
iOS 27 · Siri AI Arrives
Ships with iOS 27; the all-new Siri AI launches as an English beta with more languages in October. The A20 Pro's dual NPU gives Apple Intelligence stronger on-device compute. The Action button adds Visual Intelligence, and eSIM dual-SIM combos are more flexible.

Overall Radar: 18 Pro Max vs 17 Pro Max
Buying Guide
Pro or Pro Max? Is it worth upgrading from the 17 Pro? Everything in one read.
iPhone 18 Pro
- 6.3-inch screen feels best in hand; 211g still manageable
- 2TB storage offered for the first time — big capacity in a compact body
- Camera, chip and battery fully identical to the Max
- ¥1000 cheaper than the Max
iPhone 18 Pro Max
- 6.9-inch big screen — better for streaming and gaming
- 43-hour video playback, the strongest battery in iPhone history
- 249g takes getting used to — try it in hand first
- 2TB top config ¥21499
Is It Worth Upgrading?
Upgrading from 17 Pro: the upgrades center on the variable-aperture main camera, 2nm A20 Pro, 60W fast charging and battery life. Camera and battery are the two most tangible gains — worth it if you shoot at night often or care about battery; otherwise wait another generation.
Upgrading from 15 Pro or earlier: a near-total leap — 2nm chip, variable aperture, 48MP triple camera, 60W fast charge, WiFi 7, Apple Intelligence. Just do it.
On price: the 18 Pro starts at ¥9999 and the Pro Max at ¥10999, each ¥1000 more than the previous gen. Given the 2nm chip and variable aperture, the increase is within expectations. Pre-orders open 8 PM on Sep 12; on sale Sep 18.
