Apple’s upcoming iPhone 17 Pro models are shaping up to be some of the most significant hardware upgrades in years, according to leaks from multiple sources. Reports suggest that Apple is implementing vapor chamber cooling technology in its premium iPhone 17 Pro and iPhone 17 Pro Max models, a move aimed at improving thermal efficiency and sustaining high performance under heavy workloads.

The claim comes from Chinese leaker Instant Digital, who recently shared details on Weibo. According to the leaker, Apple’s A19 Pro chip, expected to power the iPhone 17 Pro models, will work alongside the new cooling system to minimize throttling and maintain peak performance for longer periods. This would be a first for iPhones, as vapor chamber cooling has so far been exclusive to high-end Android devices.

Earlier rumors from Chinese tech site MyDrivers suggested that the entire iPhone 17 lineup—including the standard iPhone 17 and a new "iPhone 17 Air"—would feature the technology. However, Instant Digital disputes this, claiming that only the Pro models will benefit from the upgrade.

Beyond internal changes, Apple is rumored to be making a dramatic shift in camera design. Reports indicate that the company plans to replace the signature square camera bump with a horizontal aluminum camera bar spanning the width of the device. This change is expected to be exclusive to the iPhone 17 Pro and iPhone 17 Air models, with the latter featuring a single-camera setup.

On the front, rumors surrounding the Dynamic Island remain uncertain. Jeff Pu, a well-regarded analyst, has predicted that Apple will introduce a smaller Dynamic Island on the iPhone 17 Pro Max by integrating a metalens-based Face ID system, significantly reducing its footprint. However, renowned analyst Ming-Chi Kuo has contradicted this, stating that Apple is unlikely to modify the Dynamic Island’s size across the iPhone 17 lineup.

Apple introduced the Dynamic Island with the iPhone 14 Pro in 2022, and it has since expanded to all iPhone 15 and iPhone 16 models, except for the entry-level iPhone 16e. If Pu’s predictions hold true, the iPhone 17 Pro Max could be the first to break that trend with a redesigned front-facing system.

With a combination of improved cooling, a potential redesign of the rear camera, and possible changes to Face ID, the iPhone 17 lineup is shaping up to be a notable evolution for Apple. However, as with all early leaks, details remain speculative until Apple officially unveils the devices, likely in September 2025.
