内容总结：

苹果公司于昨日正式发布iOS 26及iPadOS 26系统更新，并向兼容设备用户提供免费下载服务。本次更新涵盖多项界面与功能优化，其中最引人注目的是采用"液态玻璃"设计语言，对主屏幕图标、按钮样式及系统视觉统一性进行了全面升级。

值得注意的是，本次更新终止了对2018年发布的iPhone XR、XS及XS Max三款机型的支持。兼容设备清单显示，iPhone 11及以上机型（含第二代及后续iPhone SE）、2019年后发布的iPad系列产品均可获得新系统推送。若用户设备不在兼容列表中，虽可继续使用旧系统，但将无法获得安全更新及新功能体验。

iOS 26带来多项实用功能革新：电话应用新增"通话辅助"和集成式联系人界面；信息应用引入群组投票功能；锁屏自定义选项更加丰富；相机界面布局优化并新增镜头污渍检测功能；截图编辑工具集成AI图像识别技术，支持谷歌搜索和ChatGPT智能问答。

对于仍在犹豫是否升级的用户，苹果同步提供了iOS 18.7安全更新版本。建议用户根据设备兼容性及功能需求，通过"设置-软件更新"自主选择升级方案。据悉，苹果在六月全球开发者大会（WWDC2025）期间已对新系统进行全面测试，正式版稳定性较测试阶段有显著提升。

iOS 26 正式发布：查看您的 iPhone 是否符合免费升级条件
我们将同步告知您的 iPad 能否兼容 iPadOS 26。

您知道吗？现在可以正式为 iPhone 下载 iOS 26 了！本次更新于昨日上线，同期发布的还有 iPadOS 26 及苹果其他操作系统更新——当然，前提是您拥有兼容设备。

若手机支持最新系统，升级后将体验到诸多显著变化。您可能已听说过"液态玻璃"设计（无论有意与否），这仿佛是苹果对 Windows Vista 设计语言的致敬。虽然这是最引人注目的变化，但我们用两周时间实测了更新包含的众多功能——欢迎查阅我们的 iOS 26 上手预览报告获取更多体验细节。

不确定设备是否兼容又不想升级？别担心，我们将帮您确认设备能否运行 iOS 26。

虽然苹果去年未移除任何兼容 iPhone 机型，但 2025 年情况有变：部分机型将被淘汰。所有 iPhone 8 系列及 iPhone X 已于 2023 年停止支持，而今年，2018 年发布的 iPhone 将无法获得更新。

以下完整列出支持 iOS 26 和 iPadOS 26 的 iPhone 与 iPad 机型。欲了解最新系统更新的全部内容，可查阅我们整理的 iOS 26 功能前瞻大全。另附苹果 iPhone 17 发布会全部亮点，包括全新 iPhone Air（完整细节请参阅 Engadget 发布会图文直播）。

这三款 iOS 18 机型与 iOS 26 不兼容
与去年不同，三款 iPhone 将无法升级最新系统。以下 2018 年首发的机型无缘 iOS 26：
iPhone XR
iPhone XS
iPhone XS Max

兼容 iOS 26 的 iPhone
根据苹果官网信息，以下设备可兼容 iOS 26。简而言之，2019 年及之后发布的 iPhone 均可顺利升级：
iPhone SE（第二代及后续机型）
iPhone 11 全系列
iPhone 12 全系列
iPhone 13 全系列
iPhone 14 全系列
iPhone 15 全系列
iPhone 16 全系列
iPhone 16e
iPhone 17 全系列
iPhone Air

兼容 iPadOS 26 的 iPad
以下 iPad 机型可升级 iPadOS 26：
iPad Pro（M4 芯片）
12.9 英寸 iPad Pro（第三代及后续）
11 英寸 iPad Pro（第一代及后续）
iPad Air（第三代及后续，含 M2/M3 芯片版）
iPad（第八代及后续，含 A16 芯片版）
iPad mini（第五代及后续，含 A17 Pro 芯片版）

不想换新机怎么办？
若想继续使用不支持 iOS 26 的旧款 iPhone，虽可照常使用，但未来将无法获得安全更新，可能导致设备面临恶意软件威胁。部分需要特定 iOS 版本的应用也会停止支持，当然也无法体验 iOS 26 的新功能。

该升级 iOS 18.7 还是 iOS 26？
打开设置中的软件更新时，您会看到两个选项：iOS 18.7 和 iOS 26。前者是苹果针对安全问题的修补版本，若对 iOS 26 的重大更新持观望态度，可先选择升级以获得更多等待系统完善的时间。但若渴望体验"液态玻璃"界面和全部新功能，请直接安装 iOS 26——经过整个夏季测试版的bug修复，苹果通常会在正式版发布后迅速推出优化更新。

iOS 26 首发体验功能推荐
液态玻璃设计：主屏幕采用新应用图标设计，支持深色/透明模式，浮动式按钮设计令视觉统一性更强
电话应用革新：集成联系人、最近通话和语音信箱于同一界面，新增"等候协助"功能，客服接听时自动提醒避免等待
实时对话翻译：支持电话或短信跨语言实时翻译
群聊投票功能：信息应用新增群组投票，轻松解决"周末聚餐选哪家"引发的30+条争论
锁屏自定义升级：更酷的时钟样式、3D壁纸效果、丰富小组件和专注模式优化
闹钟贪睡时长自由设置：可设置1-15分钟任意间隔（终于告别默认9分钟）
相机界面简化：按键布局优化减少滑动操作，新增镜头污渍检测提示
智能截图功能：截图后可直接通过谷歌以图搜图（比如找明星同款毛衣），还能通过 ChatGPT 询问图片信息——编辑界面一站式实现反向搜图

苹果全球开发者大会已于 6 月 9 日开幕，欢迎通过我们的 WWDC 主题演讲图文直播回顾2025年度苹果发布的所有内容。

iOS 26 has arrived: See if your iPhone is eligible for the free update
We'll also tell you if your iPad is compatible with iPadOS 26.
Did you know you can officially download iOS 26 on your iPhone? The update became available yesterday, along with iPadOS 26 and Apple's other operating system updates. But that's assuming you have an eligible device.
If your phone is compatible with the latest OS, you'll notice substantial changes when you install the new update. You may have already heard about "Liquid Glass," which (intentional or not) is sort of like Apple's take on the old Windows Vista design language. That's the most notable change, but we spent two weeks test-driving many of the other features included in the update — you can check out our hands-on iOS 26 preview for more impressions.
Not sure if you have an eligible smartphone or tablet but also don't want to upgrade? 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, as a few models are getting the axe this time around. All iPhone 8 models and the iPhone X were the last to receive the boot in 2023, and this year, iPhones released in 2018 will be left behind.
You can find a full list of iPhones and iPads that support iOS 26 and iPadOS 26 below. To see everything you get with the latest OS updates, you can check out our big rundown of what to expect from iOS 26. Additionally, here's everything Apple revealed at the iPhone 17 launch event, including the all-new iPhone Air. (Check out Engadget's liveblog of the event for full details.)
These three iOS 18 iPhones aren't compatible with iOS 26
Unlike last year, a trio of iPhones won't be eligible to download the newest iOS. These three models that were 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
Per Apple's site, the devices listed below will be compatible with iOS 26. In short, 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
iPhone 17
iPhone 17 Pro
iPhone 17 Pro Max
iPhone Air
iPads compatible with iPadOS 26
Meanwhile, the iPads listed below 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 eventually 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.
Should I upgrade to iOS 18.7 or iOS 26?
When you first open Software Update in Settings, you'll notice two different upgrade options: iOS 18.7 and iOS 26. Apple released the former to address security issues, so you can at least download that one if you're unsure about all the big changes on iOS 26. It also gives you more time to wait for Apple to take care of any bugs on the new OS.
However, if you're excited to finally have the Liquid Glass aesthetic on your phone and use all the new features iOS 26 has to offer, go ahead and install that one. After all, Apple had all summer to weed through the most problematic bugs during its beta phase and usually releases a new update shortly after the initial launch.
iOS 26 features to try out first
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, in Apple's terms, was designed to make all of the company's operating systems more visually cohesive.
Phone app redesign: You can finally 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 brings 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 can now create polls. This can help prevent the unwanted 30+ messages when it comes to deciding which restaurant you're meeting at this weekend.
New lock screen options: More customizable iPhone lock screen options are available with iOS 26, including a cooler clock, 3D wallpaper effects, more widgets and better focus mode options.
Snooze longer (or shorter): Say goodbye to the 9-minute snooze setting in your alarms (if you want). You now have the option to change your snooze time from one to 15 minutes.
Fresh Camera app design: You'll find the Camera app is simpler to navigate in iOS 26, with all the buttons and menus located in convenient spots. That means less swiping, more photo taking. Plus, there's a new feature that tells you if your lens is too dirty.
Screenshot revamps: When you take a screenshot, you now have the option to search for the image on Google (maybe you're looking for a sweater you saw on a celeb) and you can ask ChatGPT questions about the photo — all from the edit screen. It's like a reverse image search but without all the hard work.
