The upcoming iPhone 18 Pro is anticipated to be thicker than its predecessor, the iPhone 17 Pro. This increase in thickness is attributed to changes in the aluminum frame and camera housing, with the overall body and rear camera plateau expected to be about 2mm thicker. The continued use of aluminum alloy for the mid-frame ensures excellent heat dissipation, although concerns remain about potential discoloration and surface chipping in new color options. The iPhone 18 Pro’s main camera system is set for a significant upgrade, incorporating the iPhone’s first variable aperture, which is a more expensive component than the current fixed-aperture lens. This enhancement is linked to the increased thickness of the device. The iPhone 18 Pro and iPhone 18 Pro Max are slated for a September release, alongside Apple’s inaugural foldable iPhone.
