      "text": "iOS 27 is the twentieth major release of iOS, the mobile operating system Apple develops for the iPhone. Succeeding iOS 26, it was announced on June 8, 2026, at the Worldwide Developers Conference (WWDC), alongside iPadOS 27, macOS Golden Gate, watchOS 27, visionOS 27, and tvOS 27, and became publicly available on September 14. Its main themes are a rebuilt assistant, a new generation of Apple Intelligence features, parental controls, and system-wide speed improvements. Apple's emphasis falls on three areas: Siri AI, new child safety and parental controls, and system improvements designed to make everyday tasks faster and easier."

      "heading": "Development and release",
      "text": "Following three months of beta testing preceded the public launch. Apple's first public point release, 27.0.1, arrived on September 28, 2026. The latest preview version at the time of writing was 27.2 beta 4, dated October 13, 2026. The first iPhone shipping with the software, the foldable iPhone Duo, is scheduled to launch on October 23, 2026, and Apple's press release for the iPhone Duo said the device will ship with iOS 27.1, and since the device launches on Friday, October 23, iOS 27.1 is expected by that date at the latest. Apple has also adjusted the interface so it adapts to different screen sizes and orientations, which the foldable device requires."

    {
      "heading": "Compatibility and hardware requirements",
      "text": "The baseline is broad. iOS 27 can be installed on all iPhones that run iOS 26, which includes the iPhone SE 2 and the iPhone 11 series and later. Core features therefore reach older devices, while the AI features depend on newer chips.\n\nApple Intelligence features require the A17 Pro chip or newer, as found on the iPhone 15 Pro or newer. Custom Siri voices require the A19 Pro chip or newer, which is found in the iPhone Air, iPhone 17 Pro and newer, and iPhone Duo. Sources do not fully agree on the exact model lists for Siri AI. One guide says access to Siri AI and Visual Intelligence features requires an iPhone 15 Pro or iPhone 16, while MacRumors lists the iPhone 15 Pro, iPhone 15 Pro Max, all iPhone 16 models, all iPhone 17 models, and all iPhone 18 models as supported for Apple Intelligence features."

    {
      "heading": "Siri AI",
      "text": "The most prominent change is Siri AI. Apple describes it as an entirely new version of Siri that is more intelligent, knowledgeable, and capable. It combines personal context, awareness of on-screen content, and web knowledge to support more natural conversations, richer answers, actions within apps, and chat history that carries across devices. It draws context from messages, emails, photos, and app content, with processing kept on the device where possible, according to Apple. Users can ask it to locate emails, messages, photos, and files by person, time, or location, and to perform tasks such as creating home automations or deleting items.\n\nSiri AI is still labelled as a beta. Siri AI is available, but it remains in beta. The next-generation Siri has been delayed and faces additional restrictions in the European Union."

    {
      "heading": "Apple Intelligence and writing tools",
      "text": "Apple Intelligence extends across the system. Siri can generate text from scratch in iOS 27, and a system-wide Write with Siri feature is reachable from the keyboard. Writing Tools can proofread, rewrite, summarize, or generate text system-wide wherever a user can type, with optional ChatGPT integration for heavier tasks. Users can describe in plain English what they want the iPhone to automate, which is handled by the Describe a Shortcut feature. Artificial intelligence also powers visual tools: Visual Intelligence lets users point the camera at text, objects, or scenes to copy, translate, search, or identify content, and requires an iPhone 15 Pro or any iPhone 16 model."
    },
    {
      "heading": "Apps and features",
      "text": "Photos. Photos adds Spatial Reframing editing tools, along with an upgraded Clean Up feature. Shared Albums in iCloud gain enhancements.\n\nSafari. Safari can organize tabs into topics, monitor webpages for changes, and build extensions from natural-language descriptions. Its browser Notify Me feature can watch websites for changes.\n\nMessages, Mail, and Calendar. These apps can understand context, suggest actions, and create events from simple descriptions.\n\nWallet and Apple Pay. Apple Pay receives a redesigned checkout experience online and in apps, and users can swipe between payment cards while viewing rewards balances, debit account balances, and pay-later options. Later this year, users will also be able to add funds directly to eligible debit cards.\n\nMusic and TV. The AutoMix feature, which creates smoother transitions between songs, is expanding beyond iPhone to Apple TV and HomePod. Apple Music subscribers also gain access to Hi-Res Lossless Audio on Apple TV 4K.\n\nMaps. The Flyover feature has been refreshed with more detailed visuals and smoother navigation.\n\nHealth and accessories. Cycle Tracking in the Health app adds support for perimenopause and menopause, and AirPods gain custom EQ settings.\n\nInterface and camera. The camera interface can be customized so that users can pin the controls they use most often. Liquid Glass gains adjustable opacity for buttons, toolbars, and menus."

      "heading": "Performance",
      "text": "Apple reports measurable speed gains in its own testing. Apps can launch up to 30% faster, new photos can load in the Photos app up to 70% faster, and AirDrop transfers can be up to 80% faster. The company also says iOS 27 improves transitions between Wi-Fi and cellular connections and makes Mail search more relevant."

    {
      "heading": "Parental controls and privacy",
      "text": "New parental controls and significant updates to Screen Time aim to make these tools more intuitive and easier to use. Ask to Buy and Ask to Browse require children to obtain parental permission for every app download and every new website visited in Safari. Apple's broader privacy positioning is part of the release, though the assistant's data handling is the subject of ongoing scrutiny in the European Union."

    {
      "heading": "Limitations and reception",
      "text": "Coverage of iOS 27 varies in detail. Some features are only partially documented: one review notes that specific slider controls are not yet fully documented in Apple's public materials, and another says detailed behaviors are not yet in Apple's public newsroom for some Safari intelligence features. Compatibility details for AI features also differ between sources, as noted above. The release's most anticipated capability, the new Siri, therefore remains partially available, and its full range depends on hardware and region."
