The latest flagship is here, and while the exterior design receives most of the attention, the real engineering marvels are hidden inside. In a recent detailed teardown (linked below), we got a first-hand look at the internal components of the brand-new iPhone 17 Pro Max and compared the critical hardware changes to its predecessor, the iPhone 16 Pro Max.
Here is an exhaustive, section-by-section breakdown of the most significant changes Apple has implemented in the 17 Pro Max’s internal architecture.
Display Removal and Ribbon Cable Reinforcement
The video begins by showing the careful process required to open the iPhone 17 Pro Max, noting that a full functionality check is performed beforehand as disassembly voids the Apple warranty.
- New Internal Look: Once opened, the interior of the 17 Pro Max appears remarkably clean, with most components (like the main logic board) covered by a uniform black surface. Only the Face ID sensors, Taptic Engine, and charging port are immediately visible.
- Ribbon Cable Comparison (A Major Change): The biggest hardware surprise in the display section is the revamped ribbon cable connecting the display to the logic board.
- 17 Pro Max: Features a significantly thicker and wider single ribbon cable.
- 16 Pro Max: Used a notably smaller, thinner single ribbon cable.
- The Rationale: The technicians speculate that this major change was implemented by Apple specifically to address and prevent the “Green Screen/White Screen” issues that affected previous generations of iPhones.
Section 2: Motherboard, Battery Housing, and Internal Structure
The internal components reveal Apple’s relentless push for maximizing space and improving durability.
- The Shrunken Motherboard: The logic board in the iPhone 17 Pro Max is dramatically smaller than its predecessor.
- 17 Pro Max: The board is smaller, has an unusual, non-uniform shape, and is built using a space-saving dual-layer “sandwich” design, with components stacked on both sides. This construction is thought to increase the board’s flexibility, helping it survive impact better and protecting customer data.
- 16 Pro Max: The logic board is long and considerably larger, taking up significantly more internal space.
- Why the Shrink? The main motivation for reducing the motherboard’s size was to free up space for a larger battery, allowing the 17 Pro Max to offer better battery life.
- Battery and SIM Tray Housing: The battery is secured with an aluminum plate for enhanced thermal protection.
- US vs. International: The non-US model shown still features an L-shaped cutout for the physical SIM tray. The technicians point out that the eSIM-only US variant will use this entire space for a straight, larger battery, yielding approximately 300mAh of extra capacity compared to the international model [0ent 300 MAH of extra capacity compared to the international model.
- Port Durability: The ribbon cables controlling the USB-C port have been moved and integrated into the phone’s side frame (chassis). This design choice is aimed at making the charging section more resilient to damage from drops, reducing the risk of a broken logic board connection.
Upgraded Camera Systems
Both the front and rear camera modules have seen notable physical increases in size, suggesting substantial sensor and lens improvements.
- Rear Camera Sensor Size: The iPhone 17 Pro Max features a triple-camera system with three 48MP sensors (Ultrawide, Main, Telephoto).
- 17 Pro Max vs. 16 Pro Max: All three camera modules, especially the Telephoto (periscope) lens, are physically much larger in the 17 Pro Max compared to the 16 Pro Max. The size increase is a reliable indicator of better light-gathering performance.
- Front Camera (Face ID): The front camera (18MP) and the Face ID sensor housing are also physically larger, which is attributed to performance increases and the inclusion of the new “Center Stage” feature .
Speaker System Enhancements
The audio components show a mixed bag of changes, focusing on overall sound quality but prioritizing component size.
- Stereo Speaker Box: The size of the stereo speaker box on the 17 Pro Max has been noticeably increased. This larger box is expected to deliver louder, clearer audio quality and enhance the Dolby Atmos experience.
- 16 Pro Max: The corresponding speaker section was observed to be noticeably smaller
- Main Speaker: Oddly, while the stereo speaker box is larger, the dedicated main speaker component itself is noted as being smaller than the one found in the previous model
