内容总结：

苹果iOS 26公测版第五版发布 多款旧机型将无法升级

苹果公司近日发布了iOS 26操作系统的第五个公测版本，但2018年发布的iPhone XR、XS及XS Max三款机型将被排除在本次系统升级名单之外。根据官方确认，iOS 26正式版预计将于9月16日发布会后一周向用户推送。

本次系统升级带来多项重大功能革新：全新"液态玻璃"设计语言将重构主屏幕视觉体验，带来悬浮式按钮和深色模式图标；电话应用新增"通话辅助"功能，可实时提示客服接听状态；实时翻译技术将延伸至AirPods耳机，实现跨语言通话同步转译；信息应用新增群组投票功能，方便用户协同决策。

兼容设备方面，iOS 26支持2019年后发布的所有iPhone机型，包括iPhone SE（第二代及后续机型）、iPhone 11至16全系列产品。iPadOS 26则兼容M4芯片iPad Pro、第三代及后续12.9英寸iPad Pro、第一代及后续11英寸iPad Pro、第三代及后续iPad Air、第八代及后续iPad，以及第五代及后续iPad mini。

值得注意的是，无法升级的旧款设备将无法获得后续安全更新，可能面临安全风险和应用兼容性问题。苹果将于9月9日举行iPhone 17新品发布会，届时将正式确认iOS 26的最终发布时间。

苹果iOS 26公测版第五版现已发布，但您的iPhone是否符合升级条件？请查阅支持机型列表
本文同时汇总所有确认可升级iPadOS 26测试版的iPad机型。
距离苹果iPhone 17发布会仅剩数日——这场官方确认为9月9日（周二）举行的"震撼降临"活动结束后，若遵循往年惯例，我们或能在一周后正式下载iOS 26与iPadOS 26系统。新一代操作系统将为iPhone和iPad带来重大升级：您想必听说过液态玻璃设计？这项堪称Windows Vista优化版的视觉革新，无疑是今秋最令人期待的功能之一。我们经过两周实测体验——您可查阅详细的iOS 26上手预览报告，或直接下载安装公测版第五版自行体验。该版本相较于开发者测试版（目前已更新至beta 8）更为稳定，但缺少部分尚未下放至公测版的炫酷功能（虽公测版开放所有用户下载且运行稳定，但仍需注意测试版系统存在潜在风险）。另有可靠消息称，iOS 26可能为AirPods新增实时翻译功能。若您尚未决定是否升级设备也无须担心，我们将助您快速确认现有设备是否支持新系统。

与去年全系iPhone均获支持的情况不同，2025年将有多款机型被排除在支持名单之外——2018年发布的机型此次将止步升级。若您使用的恰是这些机型，今秋将无法下载iOS 26系统（2023年淘汰的末代机型为iPhone 8全系与iPhone X）。

我们将完整披露支持iOS 26与iPadOS 26的iPhone和iPad机型清单。欲了解新系统功能详情，可查阅苹果6月9日WWDC全球开发者大会的全部发布内容。不过别对Siri的升级抱有过高期待——尽管传闻称苹果正在开发精简版AI聊天机器人以对抗ChatGPT。

三款iPhone将无法兼容iOS 26
与去年不同，今年9月新版iOS发布时，部分iPhone机型将无法升级。以下三款2018年首发的机型将无缘iOS 26：
iPhone XR
iPhone XS
iPhone XS Max

兼容iOS 26的iPhone机型
虽然苹果下月将发布的新款iPhone（暂称iPhone 17系列）尚未官宣，但根据苹果官网信息，以下机型已确认兼容iOS 26。简而言之，所有2019年及之后发布的iPhone机型均支持升级：
iPhone SE（第二代及后续机型）
iPhone 11
iPhone 11 Pro
iPhone 11 Pro Max
iPhone 12
iPhone 12 mini
iPhone 12 Pro
iPhone 12 Pro Max
iPhone 13
iPhone 13 mini
iPhone 13 Pro
iPhone 13 Pro Max
iPhone 14
iPhone 14 Plus
iPhone 14 Pro
iPhone 14 Pro Max
iPhone 15
iPhone 15 Plus
iPhone 15 Pro
iPhone 15 Pro Max
iPhone 16
iPhone 16 Plus
iPhone 16 Pro
iPhone 16 Pro Max
iPhone 16e

兼容iPadOS 26的iPad机型
以下列出的iPad及今年后续发布的新款iPad均可升级iPadOS 26：
iPad Pro（M4芯片版）
12.9英寸iPad Pro（第三代及后续机型）
11英寸iPad Pro（第一代及后续机型）
iPad Air（第三代及后续机型，含M2/M3芯片版）
iPad（第八代及后续机型，含A16芯片版）
iPad mini（第五代及后续机型，含A17 Pro芯片版）

若不想更换新iPhone怎么办？
若选择继续使用不支持iOS 26的旧款iPhone，虽可正常使用，但将无法获得安全更新，设备可能面临恶意软件威胁。部分需要新系统支持的应用程序也可能停止运行，当然也无法体验iOS 26的新功能。

iOS 26正式版何时发布？
苹果通常在新iPhone上市前数日（即9月中旬）推送新版iOS。去年iOS 18于9月16日（周一）发布，若今年保持相同节奏，新系统应于9月16日（周二）——即发布会整一周后推送。具体发布日期将在9月9日iPhone 17发布会上确认。

值得期待的iOS 26新功能
液态玻璃设计：主屏幕采用新应用图标设计，支持深色模式与全透明选项，浮动式按钮设计令人耳目一新。该设计旨在提升苹果各操作系统间的协同性。
电话应用重构：终于可在同一屏幕浏览联系人、最近通话和语音邮件信息。新增"等候协助"功能，在客服接听时发出提醒，避免长时间聆听等待音乐。
实时翻译：通过电话或短信与不同语言者交流时，系统可实现实时对话翻译。
投票功能：信息应用的群聊中将支持创建投票，轻松解决"周末聚餐选哪家餐厅"引发的30+条无效讨论。

苹果年度全球开发者大会已于6月9日开幕。欲了解WWDC 2025主题演讲实时动态与全部发布内容，请查阅我们的大会图文直播实录。

Apple's new iOS 26 public beta 5 is here, but is your iPhone eligible for the update? Check this list
We'll also tell you the iPads that are confirmed to run the iPadOS 26 beta.
In just a few days, the Apple iPhone 17 event will be here — the "awe dropping" event is officially confirmed for Tuesday, September 9. If Apple follows its past schedule, that could mean we'll get to download iOS 26 and iPad 26 exactly one week after the event. Coming with the OS 26es are huge upgrades to your iPhone and iPad's operating systems. You've heard of Liquid Glass, right? It's like the better-executed version of Windows Vista and definitely one of the cooler features coming this fall. We spent two weeks test-driving it — you can check out our detailed hands-on iOS 26 preview, or you can try it out yourself by downloading and installing the public beta 5. That software is a more stable iteration of the separate developer version, which recently hit the beta 8 waypoint, and offers a few more flashy features not yet available in the public version. (While the public beta is open to everyone and quite stable, always remember there's a degree of risk involved with beta software.) Additionally, there are credible reports that iOS 26 could bring a new live translation feature to AirPods, too. Not sure if you want to upgrade your smartphone or tablet this year? No worries, we'll help you find out if your devices will be able to run iOS 26.
While Apple didn't nix any iPhones from its eligibility list last year, that's not the case for 2025 — a few models are getting cut this time. All iPhone 8 models and the iPhone X were the last to get the boot in 2023, and this year the 2018 models are getting left behind. If you have an ineligible device, you won't be able to download iOS 26 when it becomes available this fall.
We'll get to the bottom of which iPhones and iPads will support iOS 26 and iPadOS 26 this year. To see what's coming with the latest OSes, check out everything announced at Apple's WWDC June 9 event. One thing you shouldn't immediately expect is Apple's updated version of Siri, though the company is reportedly working on a 'stripped-down' AI chatbot to compete with ChatGPT.
These three iPhones won't be compatible with iOS 26
Unlike last year, several iPhone models won't be eligible to download the newest iOS when it makes its debut in September. This trio of models first released in 2018 won't be coming to the iOS 26 party:
iPhone XR
iPhone XS
iPhone XS Max
iPhones compatible with iOS 26
While we don't yet know the new iPhones Apple will be dropping next month — though there are iPhone 17 rumors — we do know, per Apple's site, that the phones listed below will be compatible with iOS 26. Basically, if you have an iPhone that was announced in 2019 or later, you're in the clear:
iPhone SE (second generation or later)
iPhone 11
iPhone 11 Pro
iPhone 11 Pro Max
iPhone 12
iPhone 12 mini
iPhone 12 Pro
iPhone 12 Pro Max
iPhone 13
iPhone 13 mini
iPhone 13 Pro
iPhone 13 Pro Max
iPhone 14
iPhone 14 Plus
iPhone 14 Pro
iPhone 14 Pro Max
iPhone 15
iPhone 15 Plus
iPhone 15 Pro
iPhone 15 Pro Max
iPhone 16
iPhone 16 Plus
iPhone 16 Pro
iPhone 16 Pro Max
iPhone 16e
iPads compatible with iPadOS 26
The iPads listed below, and any iPads released later this year, are eligible to download iPadOS 26.
iPad Pro (M4)
iPad Pro 12.9‑inch (3rd generation and later)
iPad Pro 11‑inch (1st generation and later)
iPad Air (3rd generation and later, including M2 and M3)
iPad (8th generation and later, including A16)
iPad mini (5th generation and later, including A17 Pro)
What if I don't want to buy a new iPhone?
If you want to continue using your older iPhone that isn't supported by iOS 26, that's fine. However, you'll miss out on security updates which could potentially put your phone at risk for malware and other threats. Additionally, some apps may stop working if they require a certain version of iOS or later. And of course, you won't be able to access the latest features iOS 26 offers.
When will iOS 26 become available?
Apple usually rolls out its latest iOS in mid-September, just a few days before the new iPhones hit store shelves. Last year, it released iOS 18 on Monday, Sept. 16. If it follows suit this year, we should have access to the new operating system on Tuesday, Sept. 16 — exactly one week after the event.
Expect a confirmation of the release date at the iPhone 17 event on September 9.
iOS 26 features we're excited about
Liquid Glass design: Your home screen is getting revamped with new app icons, including dark mode and all-clear options. You'll also notice buttons with a new floating design. Liquid Glass was designed to make all of Apple's OSes more cohesive.
Phone app redesign: You'll finally be able to scroll through contacts, recent calls and voicemail messages all on one screen. It also comes with a new feature called Hold Assist that'll notify you when an agent comes to the phone so you can avoid the elevator music.
Live Translate: iOS 26 is bringing the ability to have a conversation via phone call or text message with someone who speaks another language. Live Translate will translate your conversation in real time.
Polls feature: Coming to group messages in the Messages app, chat members will be able to create polls. This can help prevent the unwanted 30+ messages when it comes to deciding which restaurant you're meeting at this weekend.
