Apple is preparing a major change in how it cools its next high-end iPhone. According to a trusted source, the upcoming iPhone 17 Pro will feature a vapor chamber cooling system—the first time this technology will be used in an iPhone.
This new system is designed to solve the growing problem of heat buildup, especially with the more powerful chips inside future iPhones. Unlike the graphite sheets used in past iPhones, a vapor chamber works by turning liquid into vapor when the phone heats up.
The vapor then spreads across the chamber, cools down, and turns back into liquid. This cycle helps move heat away from the phone’s most important parts, like the processor and graphics chip.
The new A19 Pro chip, expected to power the iPhone 17 Pro, will be able to handle demanding tasks such as high-end gaming and AI features. These tasks generate more heat, making better cooling more important than ever.
Images of the new vapor chamber design show that it will even spread heat toward the camera module—a surprising choice. Experts believe Apple may be using the phone’s metal frame and camera housing to help release heat into the air more effectively.
However, not everything is perfect yet. Sources say Apple is still facing challenges with the vapor chamber design. If the system doesn’t handle heat well enough, the phone could still get too hot, reducing performance and making it uncomfortable to hold.
The vapor chamber is expected to be exclusive to the Pro and Pro Max models of the iPhone 17 lineup, with the regular versions likely sticking to older cooling designs.
If Apple succeeds in perfecting this new system, users can expect cooler phones during heavy use, longer sustained performance, and fewer problems with overheating.
The final version of the iPhone 17 Pro will show whether Apple has solved these issues by the time it officially launches.
