Days after materials from Apple supplier Tata surfaced online, prominent Weibo leaker “Fixed Focus Digital” doubled down on his earlier claim that the iPhone 18 Pro will be thicker than the iPhone 17 Pro. Here are the details.
iPhone 18 Pro said to be 2mm thicker
Last month, Apple supplier Tata confirmed a data breach after a ransomware group posted more than 200,000 purportedly stolen files on the dark web.
The files reportedly included internal documents, component details, supplier lists, and videos of iPhone 18 Pro models undergoing drop tests. Separately circulated footage purported to show one of those tests, offering a possible look at the device’s design.
As users quickly pointed out, the iPhone in the video appeared thicker than the current iPhone 17 Pro Max, particularly around the camera plateau, possibly due to a redesigned lens system rumored to bring variable aperture to the main camera.
About a week before the drop-test footage began circulating, Fixed Focus Digital had said that “supply chain feedback” indicated the iPhone 18 Pro’s “aluminum-alloy backplate [would] increase in size by approximately 2mm.”
Today, as spotted by MacRumors, the same account said (translation ours):
Looking at the leaked Tata images confirms that both the overall iPhone 18 Pro body and the entire rear camera [plateau] have become thicker. This corresponds to the roughly 2mm increase I exclusively shared in Image 2. The final thickness will indeed be somewhat surprising.
The leaker also referred back to an earlier post in which they said the iPhone 18 Pro lineup would continue to use aluminum alloy, adding that aluminum-alloy midframes would remain common in “slab-style phones for a long time.”
Do you think a 2mm increase in thickness on the iPhone 18 Pro will be significant? Let us know in the comments.
