iPhone 18 Pro May Feature Noticeably Thicker Design Than iPhone 17 Pro

The highly anticipated iPhone 18 Pro is reportedly set to sport a noticeably thicker design compared to the current iPhone 17 Pro, according to recent leaks. Reports indicate that both the device's aluminum frame and its prominent camera housing will see an increase in thickness, suggesting a departure from the sleek profile many users have come to expect.

The leaker known as "Fixed Focus Digital" recently shared insights on Weibo, suggesting that Apple will continue to utilize an aluminum alloy for the mid-frames of its straight-edge iPhones for the foreseeable future. This approach, first introduced with the iPhone 17 Pro, is expected to remain a staple, rather than a return to titanium. Citing leaked materials reportedly sourced from Tata, the leaker claims that the overall body and the rear camera plateau of the iPhone 18 Pro will be thicker than the iPhone 17 Pro. This could translate to an approximate 2mm increase in overall thickness, a figure the leaker states they have now confirmed firsthand and expect to be "somewhat surprising" to consumers.

Previous posts from the leaker reinforce these claims. Fixed Focus Digital previously stated that the iPhone 18 Pro lineup would retain its aluminum alloy build, highlighting its "indeed excellent" heat dissipation properties. However, the leaker also advised potential buyers to exercise caution regarding new color options, referencing discoloration and surface chipping issues that have affected some iPhone 17 Pro units. In another report, supply chain feedback was said to have confirmed a significant main camera upgrade for the iPhone 18 Pro, coupled with an expected 2mm increase in the aluminum alloy back panel thickness.

Redesigned Camera System Drives Thickness Increase

The estimated 2mm increase in thickness aligns with earlier speculation. A separate post from July 4 estimated the total thickness of the iPhone 18 Pro models could range between 9.9mm and 10.9mm. This would represent a substantial jump from the 8.75mm thickness of both the iPhone 17 Pro and iPhone 17 Pro Max. Further supporting these details, dummy models shared in April hinted that the camera plateau on the iPhone 18 Pro Max might grow to 11.54mm, up from 11.23mm on the iPhone 17 Pro Max. The primary driver for this added bulk appears to be a significantly redesigned main camera system.

This new camera module is widely rumored to introduce the iPhone's first-ever variable aperture technology. This advanced component is reportedly 50% more expensive for Apple than the current fixed-aperture lens, indicating a major upgrade in photographic capabilities. Production of this sophisticated new module is reportedly ramping up with key suppliers, including LG Innotek and Sunny Optical. The iPhone 18 Pro and iPhone 18 Pro Max are anticipated to be unveiled alongside Apple's inaugural foldable iPhone model this coming September, marking a potentially transformative year for Apple's hardware lineup.

While the prospect of a thicker phone might concern some users accustomed to slimmer devices, the potential camera advancements offer a compelling reason for the change. The integration of a variable aperture could allow for greater control over depth of field and low-light performance, pushing the boundaries of mobile photography. Consumers will be keen to see if the improved imaging capabilities justify the increased dimensions when the devices officially launch.
