iPhone 17 Pro

歴史的背景

The iPhone 17 Pro and iPhone 17 Pro Max were unveiled during the Apple Event at Apple Park in Cupertino, California, on September 9, 2025, and released on September 19, 2025. Both the iPhone 17 Pro models feature a new design over predecessor models and come in three colors: Cosmic Orange, Deep Blue, and Silver. They are the first iPhone Pro models to feature an aluminum chassis rather than a titanium chassis. They are also the first iPhone Pro models that are not offered in neutral dark or black color options. The iPhone 17 Pro and Pro Max use the A19 Pro system on a chip. It incorporates the new Apple-designed N1 networking chip, part of the trend by Apple to reduce reliance on Broadcom. The Pro and Pro Max do not use Apple's new C1X modem found in the iPhone Air, opting instead for Qualcomm's Snapdragon X80. The "plateau camera" was redesigned for the first time since the iPhone 11 Pro, featuring a large horizontal camera bump and a 4× telephoto "tetraprism" camera lens, instead of the previously used 5×. The new telephoto sensor is 48 MP, allowing for the use of sensor crop to emulate an optical-quality 8× zoom. As a result, the iPhone 17 Pro and Pro Max have the best optical-quality telephoto lens on any iPhone. The increase from 5× to 8x allows for smoother transitions from 1-8× zoom levels, and the higher quality sensor allows for optical-quality zoom without digitally cropping. The front camera uses a new 18 MP Centre Stage camera with a unique square-shaped sensor, allowing the user to rotate the image taken without rotating the phone itself. The new Dual Capture feature allows the phone to take video with both the front and rear cameras at the same time. Starting with all iPhone 17 models and iPhone Air, devices based on the A19 and A19 Pro include Memory Integrity Enforcement (MIE). MIE is an always-on, hardware-and-OS, memory-safety defense that uses Apple's secure memory allocators, Enhanced Memory Tagging Extension (EMTE) in synchronous mode, and Tag Confidentiality Enforcement policies. The new Pro models introduce a new vapor chamber cooling design. This chamber is built directly into a new aerospace-grade aluminum unibody frame. Apple claims that the chamber provides up to 40% better sustained performance compared to the iPhone 16 Pro by distributing heat more efficiently from the A19 Pro chip during intensive workloads like gaming and video editing. The chamber works by using "thin, hermetically sealed chambers with a drop of water inside that cycles between liquid and gas to help dissipate heat.
