苹果 iOS 27 和 iPadOS 27 的顶级新功能

Apple’s latest iPhone and iPad software—iOS 27 and iPadOS 27—is here.

Here’s everything you need to know. iOS 27 和 iPadOS 27 主要侧重于你在日常使用中能够感受到的稳定性改进。系统包含了几项提升生活质量的优化，例如“快捷指令”（Shortcuts）的设置变得更加简单，但最大的亮点是 Siri AI 的升级。以下是你需要了解的所有信息。

Updated September 14, 2026: We’ve refreshed this story to reflect the latest updates and that iOS and iPadOS 27 are rolling out today. 更新于 2026 年 9 月 14 日：我们更新了本文，以反映最新进展，并确认 iOS 和 iPadOS 27 已于今日开始推送。

Is Your iPhone or iPad Compatible?

你的 iPhone 或 iPad 兼容吗？

Apple sometimes drops a few older devices from the support list with new versions of its operating systems, supposedly because the aging hardware can’t run the latest screen behaviors without feeling sluggish. (Apple typically supports iPhones and iPads for six to seven years.) But there’s good news this year. iPhones from 2019 and newer—the iPhone 11 and up, including the iPhone SE (2nd Gen)—will support iOS 27. 苹果有时会在新版操作系统中从支持列表中剔除一些旧设备，据称是因为老旧硬件无法在运行最新的屏幕交互时保持流畅。（苹果通常为 iPhone 和 iPad 提供六到七年的支持。）但今年有个好消息：2019 年及以后的 iPhone——即 iPhone 11 及后续机型，包括 iPhone SE（第二代）——都将支持 iOS 27。

That means any iPhone that received iOS 26 is still compatible with iOS 27. If you’re unsure of your iPhone model, go to Settings > General > About and look at the model name. 这意味着任何收到 iOS 26 更新的 iPhone 仍然兼容 iOS 27。如果你不确定自己的 iPhone 型号，请前往“设置”>“通用”>“关于本机”查看型号名称。

iPads aren’t as straightforward, as they have a unique naming structure. Apple retired the “generations” moniker and is now using the chipset to denote the iPad model. You can check your iPad model using Apple’s support documentation. A few iPads are cut off from the iPadOS 27 update, including the 8th-gen iPad from 2020 and the 5th-gen iPad Mini. iPad 的情况则没那么简单，因为它们有独特的命名结构。苹果已经弃用了“代际”称呼，现在改用芯片组来标识 iPad 型号。你可以通过苹果的支持文档查看你的 iPad 型号。部分 iPad 无法获得 iPadOS 27 更新，包括 2020 年发布的第八代 iPad 和第五代 iPad Mini。

iPad: 9th gen and later, including A16
iPad: 第九代及后续机型，包括 A16 芯片机型
iPad Mini: 6th gen and later, including A17 Pro
iPad Mini: 第六代及后续机型，包括 A17 Pro 芯片机型
iPad Air 11-inch: 4th gen and later, including M2, M3, and M4
iPad Air 11 英寸: 第四代及后续机型，包括 M2、M3 和 M4 芯片机型

iPad Pro: M4 及后续机型

How to Install iOS 27 or iPadOS 27

如何安装 iOS 27 或 iPadOS 27

The final versions of iOS 27 and iPadOS 27 are here. Before installing, it’s very important that you back up your devices. Head to Settings, tap your name at the top, and select iCloud. Then tap iCloud Backup, and tap Back Up Now. Read our How to Back Up Your iPhone or iPad guide for other methods and more details. iOS 27 和 iPadOS 27 的正式版现已发布。在安装之前，备份设备非常重要。请前往“设置”，点击顶部的姓名，选择“iCloud”，然后点击“iCloud 备份”，再点击“立即备份”。阅读我们的《如何备份 iPhone 或 iPad》指南，了解其他方法和更多详情。

Then, head to Settings > General > Software Update and choose iOS 27 or iPadOS 27 when you see the option. Installation will take several minutes, and your iPhone or iPad will restart, so set aside several minutes for the whole process. 之后，前往“设置”>“通用”>“软件更新”，在看到选项时选择 iOS 27 或 iPadOS 27。安装需要几分钟时间，你的 iPhone 或 iPad 将会重启，因此请预留出足够的时间来完成整个过程。

Siri AI, the new assistant, will ask to index your phone or iPad to learn more about you, your apps, and your data so it can be more helpful. This indexing takes a while—anywhere from a few hours to a couple of days—so be prepared to wait a bit. 新的助手 Siri AI 会请求对你的手机或 iPad 进行索引，以了解更多关于你、你的应用和你的数据，从而提供更有帮助的服务。此索引过程需要一段时间——从几小时到几天不等——所以请做好等待的准备。

Apple Intelligence Only Works on Select iPhones

Apple Intelligence 仅适用于部分 iPhone

Remember—even if older iPhones and iPads receive the iOS 27 or iPadOS 27 update, that doesn’t mean all of the new features will be available. Apple Intelligence is still only compatible with the iPhone 15 Pro and newer and select iPads, meaning that several artificial intelligence features are unavailable on older devices. 请记住，即使旧款 iPhone 和 iPad 收到了 iOS 27 或 iPadOS 27 更新，也不意味着所有新功能都可用。Apple Intelligence 仍然仅兼容 iPhone 15 Pro 及更新机型以及部分 iPad，这意味着多项人工智能功能在旧设备上无法使用。

iOS 27 和 iPadOS 27 的顶级新功能

Here’s a top-line view of some of the biggest changes coming to iOS and iPadOS 27. The updates are largely the same across both operating systems. 以下是 iOS 和 iPadOS 27 中一些重大变化的概览。这两个操作系统的更新内容基本相同。

Siri AI and a New Siri App

Siri AI 与全新的 Siri 应用

Siri is finally becoming “a more capable assistant,” or so Apple claims. The company says this is largely thanks to its third-generation foundation models, developed from the ground up with Google’s Gemini models. However, Apple says it isn’t using Google’s infrastructure to power Siri interactions and that no user data from Siri actions gets shared with Google. Siri 终于成为了“更强大的助手”，苹果如是宣称。该公司表示，这主要归功于其第三代基础模型，该模型是与谷歌的 Gemini 模型从零开始共同开发的。不过，苹果表示并未利用谷歌的基础设施来驱动 Siri 的交互，且 Siri 操作产生的任何用户数据都不会与谷歌共享。

Siri AI has an all-new look when you activate the assistant. It now resembles a glass orb. You can type or talk naturally to Siri, and there’s even a dedicated Siri app where you can revisit previous conversations or pick up where you left off on a different device. Siri is also now in the camera app, giving you a more direct way to start a visual search, much like Google Lens. You can even point the camera at a restaurant bill, and Siri can split the tab between you and your friends. 当你激活 Siri AI 时，它拥有全新的外观，现在看起来像一个玻璃球。你可以通过打字或自然语言与 Siri 对话，甚至还有一个专门的 Siri 应用，你可以在其中回顾之前的对话，或者在另一台设备上继续之前的进度。Siri 现在也集成到了相机应用中，为你提供了一种更直接的视觉搜索方式，非常类似于 Google Lens。你甚至可以将相机对准餐厅账单，Siri 就能帮你和朋友分摊费用。

The assistant understands your personal context, so it can comb through your emails, messages, and photos to find relevant information based on your query. It can then take action on your behalf, whether that’s drafting an email in a specific tone or getting wine recommendations for a particular dish. Siri’s voice is more expressive, but you can also customize the assistant’s voice, its expressiveness, and its pace. 该助手能够理解你的个人语境，因此它可以梳理你的电子邮件、信息和照片，根据你的查询找到相关信息。然后，它可以代表你采取行动，无论是用特定的语气起草电子邮件，还是为特定的菜肴推荐葡萄酒。Siri 的声音更具表现力，你还可以自定义助手的语音、表现力和语速。

Platform Stability Improvements

平台稳定性改进

Apple has focused on making iOS run faster in this update. The company says app launches are up to 30 percent faster, newly captured photos in your Photo Library load up to 70 percent faster, and AirDrop transfers are up to 80 percent faster. The iPhone will do a better job switching between Wi-Fi and cellular, so you hopefully won’t have that awkward minute with no service while you wait for your device to switch networks as you leave the house. Many of these upgrades will affect older iPhone models, like the iPhone 11, thanks to a better-optimized CPU Scheduler. 苹果在此次更新中专注于提升 iOS 的运行速度。该公司表示，应用启动速度提升了高达 30%，照片库中新拍摄的照片加载速度提升了高达 70%，AirDrop 传输速度提升了高达 80%。iPhone 在 Wi-Fi 和蜂窝网络之间的切换表现也会更好，因此当你离开家时，希望你不会再遇到那种等待设备切换网络时尴尬的断网时刻。得益于优化更好的 CPU 调度器，许多此类升级也将惠及 iPhone 11 等旧款 iPhone 机型。

“液态玻璃”优化

Hate Liquid Glass? Love Liquid Glass? You have some options to make it work for your tastes in iOS 27. Apple says it has generally updated the design language to improve readability and contrast. App icons are sharper, for example. But you now finally have a slider in the Settings menu that lets you adjust the intensity of the Liquid Glass look, from super clear to more opaque. You can customize this in Settings > Appearance > Liquid Glass. 讨厌“液态玻璃”？还是喜欢它？在 iOS 27 中，你有一些选项可以根据自己的喜好进行调整。苹果表示，他们全面更新了设计语言以提高可读性和对比度。例如，应用图标变得更加清晰。现在，你终于可以在“设置”菜单中找到一个滑块，让你调整“液态玻璃”外观的强度，从超清晰到更不透明。你可以在“设置”>“外观”>“液态玻璃”中进行自定义。
