苹果公司面向 iPhone 18 Pro 及首款折叠屏机型 iPhone Duo 等设备推送了 iOS 27.2 正式版更新 1。此次升级的核心重点在于增强 Siri AI 的功能，新增了对话记忆特性，使其能够调用信息照片、日历参与者、语音留言以及 Safari 历史记录作为信息来源 1。不过，Siri AI 的运行门槛要求设备为 iPhone 15 Pro 或更新机型，且目前该功能尚未在欧盟和中国大陆地区上线 1。此外，Siri AI 还新增了对法语、日语、韩语、葡萄牙语和西班牙语的支持 1。
在内容标识与视觉调整方面，iOS 27.2 集成了 Google SynthID 技术，用于标识 Image Playground 生成及部分经辅助编辑的照片内容 1。Apple Music 应用也进行了品牌视觉重塑，更换为黑白图标并移除了原有的红色元素 1。针对 iPhone Duo 的专属优化包括支持 USB-C Apple Pencil 以及 Edge Light（边缘补光）功能 1。同时，FaceTime Dual Capture（双摄同录）功能现扩展至群组通话，兼容 iPhone 17 系列、iPhone Air、iPhone 18 Pro 系列及 iPhone Duo 1。Multiview 多视角功能也延伸至 iPhone，允许用户同时观看最多四路体育直播（如 MLS、F1）1。
系统安全性方面，本次更新修复了超过 160 个安全漏洞，苹果表示这些漏洞均未被主动利用 1。关于内部版本号，普通机型的 iOS 27.2 版本号为 24B119，而 iPhone Duo 的版本号则为 24B91020 1。
Apple has officially released the iOS 27.2 update for iPhone 18 Pro and the inaugural foldable iPhone Duo devices 1. This release introduces significant enhancements to Siri’s artificial intelligence capabilities, particularly in memory and retrieval functions, while also delivering visual branding updates for Apple Music and improved security measures 1. The update addresses over 160 security vulnerabilities, with Apple confirming that none of these flaws have been actively exploited 1.
A core focus of iOS 27.2 is the expansion of Siri’s functionality, which now includes a new conversation memory feature capable of accessing information from photos, calendar participants, voice messages, and Safari history 1. However, this advanced Siri AI requires an iPhone 15 Pro or newer model and is currently unavailable in the European Union and mainland China 1. To support broader accessibility, the feature set has been extended to include French, Japanese, Korean, Portuguese, and Spanish languages 1. Additionally, the integration of Google SynthID tags into Image Playground and certain photo editing results aims to clearly identify content generated or assisted by AI 1.
The update also brings notable changes to system applications and device-specific features. Apple Music has adopted a new black-and-white icon design, removing previous red elements as part of a brand reshuffle 1, while the Multiview feature has expanded to iPhone users, allowing simultaneous viewing of up to four sports streams, such as MLS or F1 matches 1. For communication, FaceTime Dual Capture now supports group calls on compatible devices including the iPhone 17 series, iPhone Air, iPhone 18 Pro series, and iPhone Duo 1. Specific enhancements for the foldable iPhone Duo include internal build number 24B91020 (distinct from the standard 24B119 for other models), along with dedicated support for USB-C Apple Pencil input and Edge Light illumination features 1.
