苹果正式推出 iOS 27 与 iPadOS 27，本次更新主要聚焦于系统日常使用的稳定性提升、系统效能优化以及多项便利性改善。相容性方面，所有支援 iOS 26 的装置均能升级至 iOS 27（涵盖 iPhone 11 及后续机型），不过部分旧款 iPad 则停止支援。此外，虽然升级覆盖范围广泛，但多项核心的 Apple Intelligence 人工智慧功能仍仅限于 iPhone 15 Pro 或更新款晶片的机型使用。
Siri 迎来了重大的 AI 功能革新，采用与 Google Gemini 模型合作研发的第三代基础模型，并具备玻璃球外观、独立 App 及相机视觉搜寻等全新功能，能更深入理解使用者的个人资讯并代为执行复杂操作。在系统运作方面，应用程式启动速度加快多达 30%、照片载入及 AirDrop 传输效率显著提高，网路切换也更加顺畅，同时设定中新增了可自由调整 Liquid Glass 外观透明度的滑杆控制项。
针对家庭安全，新系统大幅强化了家长控制功能，提供更细致的网站审核、通讯安全防护与使用时间排程。照片应用程式则导入基于生成式 AI 的 Clean Up 强化版、边缘延伸及视角重构等功能，Image Playground 亦支援更逼真的图片生成。此外，捷径功能支援自然语言自动建立自动化任务，Safari 也带来了智慧标签分组、网页变动通知以及依使用者描述自动生成自订扩充功能等升级。
Apple has officially released iOS 27 and iPadOS 27, focusing primarily on everyday system stability, performance improvements, and notable quality-of-life enhancements. In terms of hardware compatibility, all devices capable of running iOS 26 can update to iOS 27—spanning from the iPhone 11 onwards—though certain older iPad models have lost support. While compatibility remains broad, key Apple Intelligence features remain exclusive to the iPhone 15 Pro and newer hardware.
A highlight of the release is the major Siri AI overhaul powered by third-generation foundation models developed in collaboration with Google Gemini models, featuring a new glass-orb design, a dedicated app, and camera visual search capable of handling contextual personal queries. Overall system responsiveness is boosted with up to 30 percent faster app launches, quicker photo loading, faster AirDrop transfers, and smoother network switching, alongside a new slider to adjust the intensity and opacity of the Liquid Glass interface.
Child safety tools have been comprehensively upgraded with website approval workflows, communication safety filtering, and structured scheduling via a refreshed parental dashboard. The Photos app gains advanced generative AI editing tools including an enhanced Clean Up, edge extension, and perspective reframing, while Shortcuts can now generate automations from natural language prompts, and Safari introduces automatic tab organization, page change alerts, and prompt-based custom extensions.
