The bottom line: Apple is shrinking the iPhone 18's Face ID module by 35% using TSMC's 2nm process and next-gen packaging, but this hardware overhaul is contributing to a $200–$300 price increase on the Pro lineup — pushing the 18 Pro past $1,399.
From Dynamic Island to Mini Dynamic Island
When Apple introduced the Dynamic Island on the iPhone 14 Pro in 2022, it turned a display cutout into an interactive software feature. Three years later, the hardware underneath is finally getting a major redesign.
Supply chain sources indicate that the iPhone 18's Face ID module will shrink by roughly 35%, dramatically reducing the visible area of the Dynamic Island — potentially changing its shape from a pill to something closer to a circle. This isn't a minor cosmetic tweak; it's the result of three converging technologies.
Tech #1: VCSEL Miniaturization + Optical Path Redesign
The heart of Face ID is a VCSEL (Vertical-Cavity Surface-Emitting Laser) that projects over 30,000 invisible infrared dots onto the user's face, read by an infrared camera. The iPhone 18's VCSEL die moves to a more advanced process node, reducing its footprint. At the same time, a redesigned prism and lens array shortens the physical distance required for the projected light path. Together, these improvements shrink the module's Z-axis (thickness) and XY-axis (board footprint) simultaneously.
Tech #2: TSMC 2nm + Advanced System-in-Package
It's widely known that the A20 chip will use TSMC's N2 (2nm) process. But the key enabler for the smaller Face ID is TSMC's new system-in-package (SiP) technology. Today's Face ID requires multiple discrete chips — a VCSEL driver IC, flood illuminator IC, and a time-of-flight processor. By integrating these into a single package (a variant of InFO or CoWoS architecture), Apple eliminates inter-chip gaps and PCB real estate. The package itself can also be thinner because 2nm's power efficiency reduces thermal dissipation requirements.
Tech #3: Unified Flood Illuminator + Dot Projector
The current TrueDepth camera system keeps the Flood Illuminator and Dot Projector as separate components. The iPhone 18 reportedly merges them into a single optical module, eliminating redundant spacing and cutting the total module size by more than a third.
The Price Warning: Who Pays for the Tech?
Hardware upgrades never come free.
- iPhone 18 Pro: $1,399 (+$200)
- iPhone 18 Pro Max: $1,499 – $1,599 (+$200 – $300)
- iPhone 18 (base): $899 – $999 (+$100 – $200)
Cost Breakdown
1. TSMC N2 wafer costs are soaring: 2nm wafers are priced 50–60% higher than 3nm equivalents. The A20 Pro die cost alone is rumored to exceed $180.
2. Early packaging yields are low: The new integrated SiP process is yielding around 70% in early production runs, and Apple absorbs the scrap cost.
3. RAM and storage are scaling up: The iPhone 18 Pro is expected to ship with 12GB of RAM and up to 2TB of storage. Memory prices haven't come down.
4. Across-the-board component inflation: According to MacRumors, the iPhone 18 Pro Max's bill of materials could rise nearly $300 compared to the iPhone 17 Pro Max.
The 2027 Pricing Trajectory
Apple has already raised prices across Macs, iPads, and services like Apple Music globally in 2026. Analysts expect this trend to continue into 2027, with the iPhone 18 becoming one of the first non-foldable flagship phones to breach $1,400. Bloomberg's Mark Gurman reports that Apple is piloting an "Apple Upgrade" installment program — a tacit admission that upfront costs are becoming a barrier.

iPhone 18 Pro: Other Rumored Specs
- Smaller Dynamic Island: Changing from a pill shape to something closer to a circle, increasing screen-to-body ratio
- A20 Pro chip: TSMC 2nm, 15–20% CPU uplift, 25–30% lower power consumption
- Variable-aperture main camera: Hardware-level aperture control for better low-light flexibility
- Larger battery: iPhone 18 Pro Max rumored at 4,288mAh
- ~2mm thicker chassis: Accommodating the bigger battery and new camera module
- Apple C2 cellular modem: Self-designed 5G chip in select regions; Qualcomm retained for the US
- Deep red finish: A new color option reportedly being tested
No Under-Display Face ID (Yet)
Despite the module shrinking 35%, Apple has not moved Face ID under the display for the iPhone 18. That technology is still expected to arrive in 2028 or later. The miniaturized module is Apple's bridge solution until true under-panel Face ID is production-ready.

Should You Wait for the iPhone 18?
For iPhone 16 or 17 users, the smaller Face ID die and 2nm chip are meaningful upgrades. But the price — potentially $1,399+ for the Pro — is a serious hurdle. The smartest move might be to wait for September's official pricing, or grab a discounted iPhone 17 Pro once the 18 launches.

FAQ
Q1: Will the iPhone 18 Face ID really be 35% smaller?
Yes, according to supply chain reports and analyst notes. The TrueDepth camera system on the iPhone 18 Pro will shrink by approximately 35% through VCSEL die shrinking, optical path redesign, and unified packaging.
Q2: Does a smaller Face ID mean the Dynamic Island disappears?
No, but it will become noticeably smaller. With less hardware underneath, the black cutout on screen shrinks, potentially changing from a pill shape to a near-circle. A true hole-free display is not expected until 2028.
Q3: Why is the iPhone 18 getting so expensive?
Three main drivers: TSMC's 2nm wafers cost 50–60% more than 3nm; the new integrated packaging suffers low early yields (~70%); and RAM/storage specs are bumping up (12GB / up to 2TB). Component costs alone may rise nearly $300 on the Pro Max.
Q4: How big is the price gap between the iPhone 18 Pro and Pro Max?
Current leaks suggest $1,399 for the Pro (up $200) and $1,499–$1,599 for the Pro Max (up $200–$300). Final pricing will be confirmed at Apple's September event.
Q5: How much will the iPhone 18 cost in my local currency?
No local pricing has been announced. Expect the typical exchange-rate-plus-tax markups. To ballpark it, wait for the USD launch price and add regional VAT/sales tax.
Q6: How powerful is the A20 chip?
The A20 Pro will be built on TSMC N2 (2nm), Apple's first mass-produced chip using Gate-All-Around (GAA) transistors. Expect 15–20% higher CPU performance, 25–30% better power efficiency, and a significantly improved GPU.
Q7: Is Apple's Face ID still better than Android's 3D face unlock?
Yes. Apple's Face ID projects over 30,000 infrared dots to build a 3D depth map, making it far more secure than camera-based 2D facial recognition common on Android. The smaller module maintains the same dot count — security is unchanged.
Q8: Should I buy an iPhone 17 now or wait for the 18?
If you want the latest tech — 2nm chip, smaller Dynamic Island, variable aperture camera — wait for the iPhone 18. If budget is a priority, grab a discounted iPhone 17 Pro after the 18 launches. The price-performance gap will be wider than ever.
