According to the well-known source Ice Universe on the Weibo platform, the iPhone 18 Pro Max will be approximately 8.8mm thick, a slight increase compared to the 8.75mm of the current iPhone 17 Pro Max.
At first glance, the difference of just 0.05mm is almost imperceptible to the touch during everyday use. Users would hardly notice the difference when holding or placing the two devices side by side. However, for Apple, this tiny change reflects an extremely significant engineering decision on the inside.
In the world of ultra-thin smartphone design, especially with Apple, a company renowned for optimizing component space down to the micrometer, even a small increase in thickness means the entire internal layout must be rearranged. And this time, Apple seems to have sacrificed thinness in exchange for two more important factors: a larger battery and a completely new camera system.
Larger battery, significantly increased weight.
According to leaked information, the iPhone 18 Pro Max will be equipped with a battery capacity of 5,100 to 5,200 mAh, a significant increase compared to the 5,088 mAh in the current iPhone 17 Pro Max eSIM version. Although the increase isn't a huge leap in terms of battery capacity, given Apple's generally conservative approach to battery size, this is considered a major step forward.
Notably, the screen size remains unchanged at 6.9 inches, and the overall exterior design is virtually the same. This suggests that Apple didn't expand the device horizontally or vertically, but primarily optimized the internal structure to create more space for the battery and camera.
The consequence is a significant increase in device weight. Sources indicate that the iPhone 18 Pro Max could exceed 240g, becoming the heaviest iPhone since the iPhone 14 Pro Max. This signals that Apple is prioritizing battery life and photography capabilities over the lightweight feel of its predecessors.
For years, Apple has strived to balance performance, design, and ergonomics. But with the iPhone 18 Pro Max , the company seems willing to sacrifice user comfort to push the boundaries of technology.
Variable aperture camera: The biggest leap forward for the iPhone in years.
The most notable upgrade of the iPhone 18 Pro Max isn't its thickness or battery, but its completely new camera system with a variable mechanical aperture.
According to confirmed information from supply chain leaks, Apple will for the first time equip the iPhone 18 Pro and iPhone 18 Pro Max with a physical aperture adjustment mechanism. This technology was previously only found on high-end compact cameras or professional cameras.
Previously, iPhone cameras used a fixed aperture, meaning the amount of light entering the sensor was always limited to a certain level. With the new mechanism, users can change the aperture size depending on the shooting conditions.
This offers a range of significant benefits. In well-lit environments, users will have better control over the depth of field, creating a natural bokeh effect similar to professional cameras, instead of relying entirely on AI processing algorithms.
When the lighting changes abruptly, the new system also helps the camera adjust exposure more accurately. In low-light conditions, a large aperture allows the sensor to capture more light, improving nighttime image quality without needing to push the ISO too high.
If this information is accurate, this could be the biggest iPhone camera revolution since Apple introduced Night Mode or the LiDAR sensor.
The "dark cherry" color will become the focal point.
In addition to the internal hardware, Apple is also testing four new color options for the high-end iPhone 18 Pro line: light blue, dark gray, silver, and especially "dark cherry"—a dark cherry red with a hint of purple.
Sources indicate that dark cherry will be the dominant color for this year's launch, similar to how Apple promoted the natural titanium color on the iPhone 15 Pro Max and the Desert Titanium color on the subsequent generation.
Apple is also reportedly improving the glass back finish to better match the color with the metal frame, reducing the perceived separation between the two materials. The goal is to create a more seamless and premium design when viewed from the back.
Dynamic Island is not gone.
One of the biggest expectations for users over the years has been for Apple to move the Face ID sensor under the screen to completely eliminate the Dynamic Island notch. However, this may not happen on the iPhone 18 Pro Max .
According to leaker Digital Chat Station , Apple will likely continue using the same mold from the iPhone 17 Pro generation to optimize production costs. This means Dynamic Island will only be slightly reduced in size instead of disappearing completely.
Industry experts now believe that under-display Face ID technology will be delayed until the next generation. This indicates that Apple has not yet achieved the desired display quality and facial recognition accuracy by placing the entire sensor under the OLED glass.
However, Apple's direction is quite clear: the company is gradually redefining the iPhone Pro line as a device that prioritizes camera performance, battery life, and a premium experience, rather than just focusing on a thin and light design.
And sometimes, an entire technological revolution begins with just a tiny change… 0.05mm.
