iPhone 18 Pro Teardown Reveals How Apple Shrunk the Dynamic Island
A new iPhone 18 Pro teardown video offers an early look inside Apple's latest flagship device, revealing how internal design changes helped shrink the Dynamic Island. From under-display Face ID components to updated camera systems and modem hardware, here is a complete breakdown of what the disassembly reveals.
What Does the iPhone 18 Pro Teardown Reveal About the Dynamic Island?
The main visual change on the iPhone 18 Pro and iPhone 18 Pro Max is a noticeably smaller Dynamic Island. The teardown video shared by REWA Technology shows how Apple achieved this physical reduction inside the chassis.
Apple reduced the footprint by repositioning the Face ID infrared camera beneath the screen in the top-left corner. Placing this infrared camera under the display panel allows the cutout area at the top of the device to take up less visible space.
To keep Face ID working properly through the screen, Apple customized the display structure directly above the infrared camera. The pixels in that specific corner feature a specialized pattern designed to let infrared light pass straight through without obstruction.
Despite this custom pixel pattern, the display looks completely normal at typical viewing angles. Users get additional usable screen real estate while retaining full Face ID functionality.
Inside the iPhone 18 Pro Teardown: Camera, Battery, and Modem Details
In addition to the screen modification, this initial iPhone 18 Pro teardown highlights major upgrades to internal hardware components. Disassembling the unit provides a clear view of the camera assembly, battery capacities, and cellular modems.
The teardown illustrates a larger 48-megapixel main camera equipped with variable aperture technology. This mechanical variable aperture system requires extra space inside the upper camera housing.
The unit featured in the video is an international variant containing a physical SIM card tray. Because the physical SIM reader takes up internal space, this model comes with a 4,056 mAh battery capacity, as expected.
In contrast, eSIM-only variants shipped in countries such as the U.S., Canada, and Japan do not include a physical SIM tray. Removing that internal component leaves extra room for a slightly larger battery capacity in those regions.
Summary of Internal Changes Discovered in the Teardown
- Smaller Dynamic Island: Made possible by repositioning the Face ID infrared camera under the display panel in the top-left corner.
- Under-Display Pixel Pattern: Specialized pixel layout allows infrared light transmission while maintaining regular screen appearance at normal angles.
- Variable Aperture Camera: Larger 48-megapixel main camera setup featuring a physical variable aperture.
- Physical SIM Battery Size: SIM tray model includes a 4,056 mAh battery, which is slightly smaller than eSIM-only models.
- Modem Variations: Features Apple's C2 modem globally, with specific regional differences expected for U.S. Pro Max models.
How Cellular Modems Differ Across iPhone 18 Pro Models
The disassembly process also offers insight into the cellular modems powering the new lineup. According to details from Apple and the teardown, wireless modem hardware varies by model and regional distribution.
The standard smaller iPhone 18 Pro utilizes Apple's in-house C2 modem in every region worldwide. Similarly, the larger iPhone 18 Pro Max relies on the Apple C2 modem across all international markets outside the United States.
Hardware analysts are still awaiting a complete disassembly of the U.S. version of the iPhone 18 Pro Max. That U.S. variant is expected to have a Qualcomm cellular modem, such as the Snapdragon X80 or Snapdragon X85.
These component choices show how Apple continues to deploy its proprietary C2 chip globally while using Qualcomm hardware for select U.S. flagship configurations.
Final Thoughts on the iPhone 18 Pro Disassembly
This early iPhone 18 Pro teardown confirms how Apple engineered a smaller Dynamic Island by placing Face ID elements under the glass. Between the under-display infrared sensor, 48-megapixel variable aperture camera, and regional modem setups, the internal layout reflects significant hardware engineering updates.
