According to the Fixed Focus Digital account on Weibo, Apple will continue to use aluminum alloy frames for the iPhone 18 Pro line instead of returning to titanium material. This source said that documents from the supply chain show that the body and rear camera cluster will be about 2mm thicker than the current generation.
This person also said that the final thickness increase may surprise many people when the product is officially launched.
The new information reinforces previous predictions by Fixed Focus Digital about Apple still maintaining the aluminum frame design on the iPhone 18 Pro line. According to sources, this material helps improve heat dissipation, although users are advised to pay attention to new color options due to the risk of color change or surface coating peeling that has appeared on some iPhone 17 Pro models.
Another report from this source said that the total thickness of the iPhone 18 Pro could reach about 9.9 to 10.9 mm, significantly higher than the 8.75 mm of the iPhone 17 Pro and iPhone 17 Pro Max.
Previous prototype models also showed that the protruding camera on the iPhone 18 Pro Max may increase to 11.54 mm, compared to 11.23 mm on the previous generation.
According to sources in the supply chain, the thicker body mainly comes from the new camera system. The iPhone 18 Pro is rumored to be the first generation of iPhones equipped with a main camera with a changed aperture, allowing adjustment of the amount of light entering the sensor to improve image quality in various conditions.
The new camera components are said to be about 50% more expensive than the fixed aperture system being used by Apple. Suppliers such as LG Innotek and Sunny Optical are said to be boosting the production of this camera module.
According to leaked information, Apple is expected to introduce the iPhone 18 Pro, iPhone 18 Pro Max and the first folding screen iPhone model in September this year.
