The Top New Features in Apple’s iOS 27 and iPadOS 27

苹果 iOS 27 和 iPadOS 27 的主要新功能

While the news coming out of WWDC 2026 is not as dramatic as last year’s iOS 26 update, where the new Liquid Glass redesign caused a big stir, Apple’s presentation still made waves. 尽管 2026 年全球开发者大会（WWDC）发布的消息不像去年 iOS 26 更新时那样具有戏剧性——当时全新的“液态玻璃”（Liquid Glass）设计引起了巨大轰动——但苹果的发布会依然激起了不小的波澜。

During the WWDC keynote, Apple walked through the changes coming to the next version of its mobile operating systems, iOS 27 and iPadOS 27. These updates will roll out to iPhones and iPads later this year, likely in September. 在 WWDC 主题演讲中，苹果详细介绍了其下一代移动操作系统 iOS 27 和 iPadOS 27 的变化。这些更新将于今年晚些时候（预计在 9 月）推送到 iPhone 和 iPad 上。

iOS 27 and iPadOS 27 focus largely on stability improvements that enrich the everyday usability of the operating systems. There are several smaller quality-of-life improvements, but the big highlight is the Siri AI upgrade. Here’s everything you need to know. iOS 27 和 iPadOS 27 主要侧重于提升系统稳定性，从而增强日常使用的体验。虽然包含了一些细微的体验优化，但最大的亮点在于 Siri 的 AI 升级。以下是你需要了解的所有内容。

Is Your iPhone or iPad Compatible?

你的 iPhone 或 iPad 支持更新吗？

Apple sometimes cuts a few older devices from the support list with new versions of its operating systems, supposedly due to hardware age. (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. 苹果有时会因为硬件老化等原因，在新版操作系统中剔除一些旧设备（苹果通常为 iPhone 和 iPad 提供 6 到 7 年的支持）。但今年有个好消息：2019 年及以后发布的 iPhone（即 iPhone 11 及后续机型，包括第二代 iPhone SE）都将支持 iOS 27。

That means any iPhone that received iOS 26 is still compatible with iOS 27. If you’re unsure about your iPhone model, head to Settings > General > About and look at the model name. 这意味着所有支持 iOS 26 的 iPhone 依然兼容 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 model. You can figure out what model iPad you have by heading here. There are a few iPads that are now 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”命名法，现在改用芯片组来标识型号。你可以点击此处查看你的 iPad 型号。目前有几款 iPad 不再支持 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 Air 13-inch: M2 and later
iPad Air 13 英寸: M2 及后续芯片机型
iPad Pro 11-inch: 2nd gen and later
iPad Pro 11 英寸: 第二代及后续机型
iPad Pro 12.9-inch: 4th gen and later
iPad Pro 12.9 英寸: 第四代及后续机型
iPad Pro: M4 and later
iPad Pro: M4 及后续芯片机型

Should I Install the Developer Beta?

我应该安装开发者测试版吗？

Anyone can install the developer beta of iOS 27 and iPadOS 27 right now. But it might not be a good idea, especially on a phone you use and rely on every day. Developer betas are notoriously buggy and sometimes have crippling issues that could make your phone inoperable. If you really want to give it a try, maybe use an older iPhone you have lying around. 任何人现在都可以安装 iOS 27 和 iPadOS 27 的开发者测试版。但这可能不是个好主意，尤其是对于你每天依赖的手机而言。开发者测试版以 Bug 多而著称，有时甚至会出现导致手机无法使用的严重问题。如果你真的想尝试，建议使用闲置的旧 iPhone。

If you want to try it no matter what, make sure to back up your iPhone before installing the update. Then, head to Settings > General > Software Update > Beta Updates and choose iOS 27 Developer Beta or iPadOS 27 Developer Beta. You should see an option to install it right away. (Installation will take several minutes.) 如果你执意要尝试，请务必在安装更新前备份 iPhone。然后，前往“设置” > “通用” > “软件更新” > “Beta 版更新”，选择“iOS 27 Developer Beta”或“iPadOS 27 Developer Beta”。你应该会看到立即安装的选项。（安装过程需要几分钟。）

The public beta is often more stable and might be a better time to try the software. It’s usually available in July, and the final version often rolls out mid-September. 公测版通常更稳定，或许是尝试新系统的更好时机。公测版通常在 7 月发布，而正式版往往在 9 月中旬推出。

Apple Intelligence Only Works on Select iPhones

Apple Intelligence 仅适用于部分 iPhone

Remember—even though older iPhones and iPads may 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 on the iPhone 15 Pro and newer and select iPads, meaning that several new artificial intelligence features are unavailable on older devices. 请记住，尽管旧款 iPhone 和 iPad 可能收到 iOS 27 或 iPadOS 27 的更新，但这并不意味着所有新功能都能使用。Apple Intelligence 仍然仅兼容 iPhone 15 Pro 及更新机型以及部分 iPad，这意味着旧设备无法使用多项新的人工智能功能。

iOS 27 和 iPadOS 27 的主要新功能

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 即将带来的一些重大变化。这两个操作系统的更新内容基本一致。

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, which were developed from the ground-up with the help of Google’s Gemini models. However, Apple says it is not using Google’s infrastructure, 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。苹果表示，这主要归功于其第三代基础模型，该模型是在谷歌 Gemini 模型的帮助下从零开始开发的。不过，苹果强调并未采用谷歌的基础设施，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 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. 当你激活 Siri AI 时，它拥有全新的外观，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应用程序，让你回顾之前的对话，或在不同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，类似于 Google Lens。你甚至可以将相机对准餐厅账单，让 Siri 帮你分摊费用。

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 to draft an email in a specific tone or get wine recommendations for a particular dish. Siri’s voice is more expressive, but you can also customize the assistant’s voice and adjust its expressiveness and 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。它还可以代表你采取行动，无论是用特定的语气起草邮件，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，并调整其表现力和语速。

Platform Stability Improvements

平台稳定性改进

One of the most appreciated features will be Apple’s improvements in making iOS run faster. 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 even do a better job of switching between Wi-Fi and cellular, so you hopefully won’t have that awkward minute with no service as you wait for your device to switch networks while leaving the house. Many of these upgrades will affect older iPhone models, like the iPhone 11, thanks to a better-optimized CPU Scheduler. 最受好评的功能之一将是苹果在提升 iOS 运行速度方面的改进。苹果表示，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，这样当你离开家时，就不必再经历那段等待设备切换网络时尴尬的“无服务”时间。得益于优化后的 CPU 调度器，许多此类升级也将惠及 iPhone 11 等旧款机型。

“液态玻璃”细节优化

Hate Liquid Glass? Love Liquid Glass? Well, 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”菜单中通过滑块来调整“液态玻璃”效果的强度，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。
