iOS is Apple's proprietary mobile operating system. Running exclusively on iPhones, it is the software that powers your entire device.
Apple constantly updates iOS to introduce new features, remove bugs, and improve your data security. Updating your iOS to the latest version will keep your device safe and provide the best experience with Apple's products.
Apple just announced iOS 27 at WWDC 2026. It will be released this fall and include features like Siri AI, new parental controls, and Liquid Glass customizations.
Until iOS 27 is released, iOS 26.5.1 is the newest iOS version release. It's a software update that addresses a battery charging issue that prevented wired charging on the iPhone Air and iPhone 17 models when the battery was nearly drained. This update is only available to the iPhone 17 models and iPhone Air.
We've got all the details surrounding the upcoming release of iOS 27. Read on to learn how to update Apple's most recent version of iOS, find out which iPhones are compatible with iOS 27, and discover more about the latest features.
What is iOS?
Originally developed in 2007, iOS is Apple's mobile phone operating system. Engineered to run exclusively on Apple hardware, iOS is the software that runs your iPhone. In 2019, Apple rebranded its iPad software as iPadOS, though the two systems are closely linked. Similarly, the Apple Watch runs watchOS, while the Apple TV runs tvOS.
Note that iOS is not the same as Android, which is Google's open-source smartphone operating system. Android runs devices like the Google Pixel and Samsung Galaxy.
A big part of the Apple experience is iCloud, which handles syncing and backups across all your devices. Here's our guide to what iCloud is and how it works if you want to dig deeper.
What is the latest version of iOS?
iOS 26.5.1 is the newest iOS version release, but it is only available for iPhone 17 models and the iPhone Air. It's a software update fixing a known bug that prevented wired charging on affected devices when the battery was nearly drained.
iOS 27 is the future update that will be released later this year. While not as large as iOS 26, it still includes major features like Siri AI, Apple Intelligence expansions, additional parental controls, and Liquid Glass refinements.
Why is it called iOS 27?
Apple is following the same naming system it created last year with iOS 26. Instead of naming the new operating systems sequentially, iOS 26 was named after the year 2026, when most of its features were released. iOS 27 will follow this pattern, seeing many of its core updates come out next year during 2027.
Apple is also unifying all of its operating systems around a common design and the 2027 name. In addition to iOS 27, the new software systems will also include:
- watchOS 27
- tvOS 27
- macOS 27
- visionOS 27
- iPadOS 27

*Expected 2026 models.
Apple announced that iOS 27 will cover the same devices as iOS 26. That's a pleasant surprise, as iOS updates usually drop the oldest models from the previous generation. No devices were discontinued during this software generation.
If you have a compatible device, make sure you're ready to update to iOS 27 when it launches this fall. Earlier versions of iOS are more susceptible to security threats and major bugs.
The history of iOS
The launch of iOS coincided with the release of the first-generation iPhone in 2007. Apple releases a new version of iOS annually, with iterative updates throughout the year. Progressive software overhauls deliver bug fixes, improvements to existing functions, and brand-new features. In 2008, the iOS App Store launched, allowing access to a few hundred apps. Since then, the roster of iOS apps has risen beyond 2 million.
What's new in iOS 27?
With each annual iOS update, Apple introduces important security updates, bug fixes, Apple Intelligence capabilities, and new features. iOS 27 is a more focused update than last year's sweeping redesign, but there are still several meaningful changes. Here are the biggest updates coming with iOS 27.
Siri AI: Apple Intelligence finally comes to Siri

Apple first promised an AI-enabled Siri back in 2024 with iOS 18. Finally, after two years, iOS 27 is delivering on that promise.
Siri AI is a completely rebuilt assistant powered by the next generation of Apple Intelligence. The major upgrades include:
- Personal context understanding: Siri can pull a restaurant recommendation from a text thread or surface a hotel confirmation buried in your email.
- Onscreen awareness: Siri can answer questions about whatever is currently on your screen.
- New dedicated Siri app: Apple syncs your conversation history across all Apple devices via iCloud, so you can pick up a thread on iPhone that you started on your Mac.
Parental Controls: A serious upgrade for child safety

Apple is overhauling its child safety tools with iOS 27, organized around four key areas:
- What kids can see: Parents choose which apps are available when children set up their phone, and can require approval before a child accesses any new website in Safari or downloads a new app.
- Who they can talk to: Parents manage contacts across Messages, FaceTime, and Phone, and can require approval before kids add anyone new. Communication Safety now also blocks violent or graphic content in shared images and videos.
- When they can access apps: Time Allowances let parents set limits by app category (Entertainment, Games, or Social Media), with daily schedules that restrict access during specific times of day, like school hours.
- How parents stay informed: A redesigned Screen Time dashboard shows daily average usage and top apps. Parents can pause device access with a single tap, or extend it when kids need a few more minutes with their device.
Photos: Reframe, Extend, and a better Clean Up

iOS 27 brings three image editing upgrades to the Photos app, all powered by Apple Intelligence:
- Clean Up: This existing tool gets a quality upgrade that produces more natural-looking results when removing objects from pictures.
- Extend: A new tool that expands the edges of an image to give subjects more breathing room, with Apple Intelligence using image generation to fill in what's missing.
- Reframe: This new tool allows users to adjust a photo's composition by touching and dragging to shift the perspective in real time. New content is only generated where the perspective changed, keeping the rest of the image intact.
Apple Intelligence updates: Safari, Shortcuts, Passwords, and more

Beyond the Photos app, iOS 27 pushes Apple Intelligence into several other native apps. Many of these are agentic AI tools, meaning Apple Intelligence can execute tasks independently without additional input from you. Here are the top new Apple Intelligence features in apps:
- Safari: Tabs are automatically organized by topic, a new Notify Me feature monitors webpages for changes, and you can create custom extensions just by describing what you want.
- Shortcuts: A new Describe a Shortcut feature lets you build automations in plain language.
- Image Playground: Now supports photo-realistic image generation, with edits via natural language or by tapping and circling objects directly.
- Passwords: Apple Intelligence can now automatically fix weak or compromised credentials with a single tap, navigating websites on your behalf to update them.
- Home app: Related smart home notifications are consolidated into single activity summaries, and HomeKit Secure Video cameras gain generated video descriptions and searchable clip history.
- Call Context: When you call a business, the Phone app can automatically surface relevant info—like a confirmation number—from other apps, without listening to your call.
Liquid Glass refinements: Bug fixes and customization

Liquid Glass was the defining change of iOS 26, offering a new visual interface across Apple's entire ecosystem. However, the reaction has been mixed. The translucent look is distinctive, but some users struggled to read text against the clear backgrounds, and the system shipped with several visual bugs.
iOS 27 is addressing problems in Liquid Glass with:
- Intensity controls: New settings let you dial back the Liquid Glass effect to your preference.
- Bug fixes: Apple is resolving the visual bugs that have accumulated since the iOS 26 launch, like laggy screens or sluggish animations.
Liquid Glass isn't completely going away, but this is an acknowledgment from Apple that the design's execution has been flawed throughout iOS 26.
How to update to iOS 27
iOS 27 isn't available for download yet. We expect it should be available in September of 2026. For now, iOS 26.5.1 is the newest version of iOS.
It's important to make sure you update to iOS 26.5.1 if your device is eligible.
If it's been a while or you've never performed a software update, you'll want to do so immediately. While app improvements and emojis are nice, iOS updates also frequently include critical safety updates that improve the security of your device.
Here's how to update to the latest version of iOS:
- Head to Settings > General > Software Update
- Choose Download and Install to obtain the most recent software release for your iOS device.
Since upgrades are typically large, we suggest downloading over Wi-Fi.
You can also enable automatic iOS updates by:
- Navigating to Settings > General > Software Update
- Tapping Automatic Updates
- Toggling on Download iOS Updates and Install iOS Updates.
However, if it's been a while and your Apple iPhone still hasn't updated, go ahead and perform a manual update. As Apple's Craig Federighi reveals, iOS auto-updates often arrive several weeks after release.
Best iPhones for iOS 27
Whether you're an existing iPhone user looking for an upgrade or switching from Android, a new iPhone is a compelling purchase. Our favourite iOS devices include the newest iPhone 17 series and last year's iPhone 16 series. Both of these series have access to Apple Intelligence.
Older models such as the iPhone 15, iPhone 14, and iPhone SE 3rd gen (2022) are also excellent options for iOS 26, especially if you can find a good deal. While these devices don't include the newest bells and whistles, they do have 5G connectivity and will let you hook up to Apple's ecosystem at a cheaper price point.
