Leaked Document Suggests iPhone 17 Pro to Feature 8x Zoom and Vapor Chamber Cooling

A leaked document from a South Korean carrier suggests that Apple's forthcoming iPhone 17 Pro and Pro Max models will feature significant hardware upgrades, including an 8x optical zoom telephoto lens and a vapor chamber cooling system.

The document indicates that both Pro models will be equipped with triple 48-megapixel rear cameras, with the telephoto lens offering 8x optical zoom. This would mark a notable advancement from the 5x zoom available on the iPhone 16 Pro models. Additionally, the Pro models are expected to support 8K video recording, a feature that would benefit from improved thermal management.

To address potential overheating during intensive tasks, the iPhone 17 Pro and Pro Max are rumored to incorporate a vapor chamber cooling system. This technology, already present in some high-end Android smartphones, utilizes a sealed chamber containing liquid that evaporates when heated, effectively dissipating heat away from critical components.

The leaked document also mentions that the Pro models will be powered by Apple's new A19 Pro chip, paired with 12GB of RAM, and will feature a new aluminum unibody chassis. Battery capacities are expected to increase, with the Pro Max model reportedly housing a 5,000 mAh battery, up from 4,676 mAh in its predecessor.

While the authenticity of the leaked document remains unverified, the details align with previous reports about the iPhone 17 Pro's anticipated features. Apple is expected to unveil the iPhone 17 lineup at its upcoming event on September 9, 2025.
