As of today, multiple reputable outlets and leaks consistently state that Apple’s iPhone 17 Pro and Pro Max are rumored to adopt a vapor chamber cooling system, marking a first for the iPhone lineup.
-
The leak includes an image of a copper thermal plate from leaker Majin Bu
-
Analysts like Ming-Chi Kuo have previously indicated that only Pro and Pro Max models would adopt this feature
-
The expected benefit: better thermal management during continuous high-demand tasks — gaming, on-device AI, video recording — reducing throttling and overheating
Does the iPhone 16 Pro have vapor chamber cooling?
No — the iPhone 16 Pro does not feature a vapor chamber. Instead, it continues using graphene sheets combined with passive metal frames and battery heat-spreading techniques to manage internal temperatures.
While Apple resolved many of the heating issues from earlier models (like the iPhone 15 Pro series), users still report the 16 Pro getting warm under sustained load
🔍 What is the cooling technology on the iPhone?
Under heavy usage like intense gaming or video editing, these can reach their limits, triggering thermal throttling and warming the device noticeably .
Enter the vapor chamber: a sealed, vacuum-filled copper plate containing a tiny liquid reservoir. Heat causes the liquid to vaporize, spreading it across the plate; as the vapor cools, it condenses and cycles back. This process dramatically improves heat transfer—often 3–5× better than graphite.
Rumored iPhone 17 Pro Vapor Chamber System
The leaked copper vapor chamber plate—likely paired with micro-perforated copper patterns—suggests a hybrid cooling approach: traditional graphite layers remain, now supplemented with a vapor chamber for enhanced thermal distribution.
Key benefits:
-
Reduced thermal throttling: The A19 Pro chip can sustain peak performance
-
Cooler operation under pressure: Users should experience lower surface temperatures during long sessions of intensive use .
-
Gaming and battery improvements: Cooler internals help extend battery longevity and provide smoother, more consistent game performance
Possible trade-offs:
-
Adding a vapor chamber—and perhaps switching the 17 Pro’s frame from titanium back to aluminum—might impact device thickness or weight slightly.
-
The system is reportedly still being refined before the rumored September release
✅ Summary: What’s new over the iPhone 16 Pro?
-
First-ever vapor chamber cooling on an iPhone, doubling down on passive methods with advanced thermal tech.
-
Expected 3–5× better heat transfer versus graphite-only systems.
-
Better thermal stability, especially during gaming and on-device AI workloads — cooling to stay cool under prolonged load.
-
Continued Pro/Pro Max exclusivity, linked to the higher-power A19 Pro chip.
-
Design changes include a possible shift to aluminum and thicker internals—but with noticeable performance gains.

The rumored vapor chamber system in the iPhone 17 Pro represents a significant leap forward in thermal management compared to the iPhone 16 Pro. While previous iPhones have relied solely on passive cooling solutions like graphite and metal frames, the addition of a vapor chamber could dramatically improve sustained performance and user comfort—especially during high-intensity tasks like gaming, 4K video capture, or AI processing. If these rumors hold true, the iPhone 17 Pro may finally close the gap with Android flagships in terms of advanced cooling, making it the most capable and future-proof iPhone yet for power users. As always, we’ll know for sure this September when Apple officially unveils the device.
