iOS 27 and iPadOS 27 don’t drop support for any iPhones—and just a few iPads

iOS 27 和 iPadOS 27 未淘汰任何 iPhone 机型，仅少量 iPad 受影响

If you’re using older iPhone or iPad hardware and you’re hoping to keep running Apple’s latest operating systems, this year’s releases bring mostly good news. The iOS 27 update will run on all iPhones that can run iOS 26, all the way back to the iPhone 11 and second-generation iPhone SE.

如果你正在使用较旧的 iPhone 或 iPad 硬件，并希望继续运行苹果最新的操作系统，那么今年的发布带来了大多是好消息。iOS 27 更新将支持所有能够运行 iOS 26 的 iPhone 机型，涵盖范围一直追溯到 iPhone 11 和第二代 iPhone SE。

The iPadOS 27 update is slightly less generous, dropping support for the 3rd-generation iPad Air, 8th-generation iPad, and 5th-generation iPad mini (all of these devices used an older A12 Bionic chip; supported devices now use an A13 or better). Apple says owners of older devices should see performance improvements in iOS 27, thanks in part to an updated CPU scheduler. This scheduler was apparently already included with newer iPhones but has been ported back to older devices with this release.

iPadOS 27 的支持范围则稍显局限，停止了对第三代 iPad Air、第八代 iPad 和第五代 iPad mini 的支持（这些设备均搭载较旧的 A12 仿生芯片；目前受支持的设备均使用 A13 或更高版本的芯片）。苹果表示，得益于更新后的 CPU 调度程序，旧设备用户在 iOS 27 中应能感受到性能提升。该调度程序此前已应用于较新的 iPhone，此次更新将其移植到了旧设备上。

But many of the new features Apple mentioned require support for Apple Intelligence, which remains confined to newer devices with at least 8GB of RAM. Apple Intelligence still requires an iPhone 15 Pro or newer, an iPhone 16 or newer, or an iPhone Air. On the iPad, support requires an iPad Air or iPad Pro with an M1 or newer.

然而，苹果提到的许多新功能都需要“Apple Intelligence”的支持，而该功能仍仅限于配备至少 8GB 内存的较新设备。Apple Intelligence 依然要求 iPhone 15 Pro 或更新机型、iPhone 16 或更新机型，以及 iPhone Air。在 iPad 上，则需要搭载 M1 或更新芯片的 iPad Air 或 iPad Pro。

And the more capable local models Apple announced have even more restrictive system requirements. They need a newer Apple Silicon chip and at least 12GB of RAM, which means they’ll only work on the iPhone 17 Pro, the iPhone Air, the recently introduced M4 iPad Air, or the M4 or M5 iPad Pro.

此外，苹果宣布的更强大的本地模型对系统要求更为严苛。它们需要更新的 Apple Silicon 芯片和至少 12GB 的内存，这意味着它们仅适用于 iPhone 17 Pro、iPhone Air、近期推出的 M4 iPad Air，或是 M4/M5 iPad Pro。

The first iOS 27 and iPadOS 27 developer betas are available now, and a version aimed at public beta testers will follow in July. The final releases will land in the fall, as they typically do.

首个 iOS 27 和 iPadOS 27 开发者测试版现已发布，面向公开测试人员的版本将于 7 月推出。正式版将如往常一样在秋季发布。
