"The Cooling Revolution" Arrives! iPhone 17 Pro Changes the Game with a Vapor Chamber

1. Introduction — Mastering "Cooling" to Dominate the High-End Market

"The iPhone 17 Pro/Pro Max will adopt a 'vapor chamber'." This announcement sent ripples through the mobile industry, as a technology familiar in the world of gaming PCs and Android flagships finally makes its way to the iPhone. The vapor chamber is a type of thin heat pipe that dissipates heat through latent heat, essential for maximizing chip performance over extended periods.ndtvprofit.commacrumors.com

3. "Full Power for Long Periods" with Vapor Chamber

Heat generation has always been a challenge for the iPhone. In the A17 Pro generation, there were reports that the temperature reached 44°C within 10 minutes during 'Genshin Impact' at 90 fps, causing the CPU/GPU to throttle. The vapor chamber evenly disperses heat and continuously dissipates it through the evaporation-condensation cycle. The Galaxy S24 Ultra, with the same structure, reportedly kept temperature rise under 5°C even during 30 minutes of 4K60p recording. If the iPhone 17 Pro achieves similar effects, "sustained performance" in high-load workloads like video shooting, VR gaming, and AI inference becomes more realistic.macrumors.comtomsguide.com

4. Camera System — The Impact of "3-Stage Stacked" Sensors

According to leaked diagrams, the wide-angle camera evolves from the traditional 2stack CMOS to a 3stack structure, improving dynamic range and burst shooting speed. It's expected to achieve sufficient exposure in low light without reducing shutter speed to 1 Hz. Additionally, the new periscope employs a 6-element lens and freeform prism, achieving 7× optical / 30× hybrid zoom.ndtvprofit.comfinancialexpress.com

Reactions on Social Media

• @MajinBuOfficial"The 3stack sensor seems to be a custom version of Sony LYT-900. If low-light noise matches Pixel's level, it could be unbeatable."x.com

• On Reddit /r/apple, there are also voices saying, "If it becomes 2 mm thinner, please remove the camera bump."reddit.com

5. A19 Pro and 12 GB RAM — The Foundation of the Mobile AI Era

Rumors suggest that Apple is testing the on-device LLM "Apple Grok" on some models starting with iOS 18.4. The NPU computational performance of the A19 Pro is said to exceed 45 TOPS, with evaluation units reportedly capable of executing Stable Diffusion Lite-class text-to-image generation in under 2 seconds. The 12 GB RAM alleviates the bottleneck of "memory availability" in large model inference. Even when deploying Mobile LLAMA-3-8B with 4-bit quantization, it fits within just under 10 GB, making multitasking with Safari and the camera more feasible.ndtvprofit.comlivemint.com

6. New Material Frame and Coexistence with the "Air" Line

The aluminum + glass hybrid aims to achieve "a balance of bending rigidity and lightweight" similar to the MacBook Air. According to leaked CAD, the thickness is 7.1 mm (0.9 mm thinner than iPhone 16 Pro). Meanwhile, there is information that a further slimmed-down iPhone 17 Air (tentative name) will be introduced as a separate line, suggesting a strategy where Pro users can choose between "thinness or performance."reddit.comndtvprofit.com

7. X and Reddit in Frenzy! The Sentiment on Social Media

@MacRumors"Judging from the part photos, the chamber is 15% larger than that of the Galaxy S25. Apple is serious."
@Tech_InsiderJP"12 GB RAM is welcome. But AI will be tough without at least 256 GB of basic storage."
Reddit /r/iphone"I'm happy about the heat management, but if the price approaches $2,000, I might go for the Pixel Fold."

The impression is 60% positive, 30% cautious, and 10% negative, with common concerns about price and battery life. As cooling performance increases, OEMs are often tempted to make batteries thinner—where Apple strikes the balance will be key.twitter.comreddit.com

8. Comparison with Competitors — Galaxy S25 Ultra, Pixel 10 Pro

• Performance: A19 Pro + 12 GB RAM's Geekbench multi-core prediction is 9,500 points, 15% higher than Snapdragon 8 Gen 4.

• Cooling: The vapor chamber area is said to
