While the tech world is still digesting the iPhone 17, the rumor mill has already shifted into high gear for September 2026. A comprehensive research note from Jeff Pu of GF Securities has outlined a massive technological pivot for the iPhone 18 Pro series.
This isn’t just an incremental update; Apple is reportedly preparing to take total control of its hardware stack while pushing the boundaries of physical camera hardware and battery density.

The A20 Pro Revolution: Entering the 2nm Era
The headline feature of the 2026 lineup is undoubtedly the A20 Pro chip. According to internal leaks, this will be the industry’s first consumer chipset manufactured using TSMC’s 2nm process.
-
The Packaging: Apple is rumored to use a new WMCM (Wafer-Level Multi-Chip Module) packaging method, integrating 12GB of RAM directly onto the wafer.
-
The Gains: Early benchmarks suggest the A20 Pro will be 15% faster than the A19 Pro while consuming 30% less power, providing the thermal headroom needed for more advanced Apple Intelligence tasks.
Photography Peak: Variable Aperture and Upgraded Optics
For the first time in iPhone history, Apple is moving away from fixed-aperture lenses. The iPhone 18 Pro’s 48MP Main Fusion camera will feature a mechanical variable aperture.
-
Low Light Mastery: In dark environments, the lens can open wider to flood the sensor with light.
-
Pro Control: In bright daylight, the aperture can narrow, increasing the “depth of field” to ensure both the foreground and background remain sharp—a feature currently only possible via software simulation.
-
Telephoto Boost: The periscope lens is also expected to receive a wider aperture, improving night-time zoom performance and reducing noise.

Investigative Angle: The End of the Qualcomm Era
Our investigation into Apple’s supply chain reveals that 2026 marks a strategic “divorce” from Qualcomm. The iPhone 18 Pro will likely be the first flagship to ship with the Apple C2 modem.
The Strategy: By moving to an in-house modem, Apple can achieve “tight integration” between the A-series processor and the cellular radio. This enables exclusive features like “Limit Precise Location,” which prevents carriers from pinpointing your street address, and NR-NTN support for full-speed 5G satellite internet access in dead zones.
Design and Durability: The Heaviest Pro Max Yet

Apple’s pursuit of “all-day-plus” battery life comes with a literal weight. The iPhone 18 Pro Max is rumored to pack a 5,200mAh battery (international variant), up from the 5,088mAh in the 17 Pro Max.
-
Weight Warning: Analysts warn that this denser battery, combined with the complex variable aperture hardware, could push the Pro Max’s weight beyond 240 grams, making it the heaviest iPhone ever produced.
-
The Screen: While sizes remain at 6.3 and 6.9 inches, the Dynamic Island is expected to shrink by roughly 35%. Apple is reportedly relocating the Face ID flood illuminator beneath the display, leaving only the selfie camera and infrared sensor visible.

Next Steps
If you are holding onto an iPhone 14 or 15, you should consider skipping the iPhone 17 and waiting for the 18 Pro’s 2nm jump, as the A20 Pro represents a much larger architectural shift than the current 3nm chips. Furthermore, if you are a mobile photographer, you should start familiarizing yourself with manual aperture controls on mirrorless cameras, as the iPhone 18 Pro will likely bring these “pro” settings to the stock Camera app.
