Apple might be planning a big upgrade for the iPhone 17 Pro and Pro Max, expected to launch in September. According to new leaks and industry sources, the company could introduce a vapor chamber cooling system. If that happens, it would be a major change in how Apple manages heat, performance, and battery efficiency in its top-end iPhones.
What to Expect from the iPhone 17 Pro Max
The iPhone 17 Pro Max is expected to come with a range of upgrades as part of its final design, according to recent reports. Tech YouTuber Matt Talks Tech says the phone may feature a larger battery, support for 8K video, a 48MP zoom camera, Apple’s new A19 Pro chip, Wi-Fi 7, 12GB of RAM, dual video recording, and a new Sky Blue color option.
Vapor Chamber Cooling: A Game-Changer?
One of the more talked-about changes is the possible use of a vapor chamber cooling system, something that’s already common in gaming and high-end Android phones. TechRadar, citing unnamed sources, says this system could help the new iPhones stay cooler and maintain better performance during tasks like gaming or editing 4K videos.
A known leaker named Majin Bu also posted an image on X (formerly Twitter) that appears to show Apple testing this cooling tech. While his predictions haven’t always been accurate, he has been right about Apple prototypes in the past, as noted by MacRumors.
According to leaker Majin Bu, the vapor chamber cooling system will probably be limited to just the iPhone 17 Pro and Pro Max models. This goes against earlier rumors that suggested the whole iPhone 17 lineup – including the standard model and the rumored “iPhone 17 Air” – might get the upgrade.
Why it matters
Right now, iPhones use graphite pads to manage heat, but they can struggle with heavy use. A vapor chamber cooling system could change that. It works by using liquid inside a sealed metal unit — as the phone heats up, the liquid turns to vapor, spreads the heat, and then cools back into liquid, repeating the process.
What it helps with
This type of cooling can keep performance steady without slowing the processor down, improve battery life, and protect internal parts from overheating – especially useful for Apple’s powerful A-series chips.
What’s next
Apple hasn’t confirmed anything yet, but several leaks suggest the iPhone 17 Pro and Pro Max will include this feature. If true, the new models could stay cooler and perform better, especially during demanding tasks. The iPhone 17 lineup is expected to launch in September 2025.
