Apple iOS 27 Is Officially Here: 10 New iPhone Features Worth Trying First

Apple has pulled the trigger on iOS 27, and it is already sitting in the Software Update tab of hundreds of millions of iPhones around the world. The rollout began on Monday, September 14, 2026, roughly three months after Apple first showed off the update at WWDC in June, and it lands as the company’s biggest software release of the year. If you have spent the summer watching beta screenshots trickle out on tech blogs, the wait is over. iOS 27 is now a free download for anyone running an iPhone 11 or newer.

What makes this release different from the usual autumn refresh is how much of it is built around a genuinely reworked Siri. Apple has spent the past two years playing catch-up on AI, and iOS 27 is the update where that work finally shows up in the hands of ordinary users. But Siri AI is far from the only reason to update. Apple also refined the Liquid Glass design language it introduced last year, sped up dozens of everyday interactions, and quietly reworked how Photos, Safari, Shortcuts, and even AirPods behave.

Below is a rundown of the ten features that are worth exploring first, what they actually do, and which iPhones can use them.

iOS 27 At A Glance

1. A Noticeably Faster iPhone, Even on Older Models

Not every headline feature in iOS 27 needs an AI chip to matter, and the performance work is the clearest example. Apple has trimmed the fat out of a long list of everyday actions. Animations feel snappier, apps open a beat quicker, and the App Library and Home Screen respond with less lag when you swipe between pages. AirDrop transfers wrap up faster, the keyboard pops up with less delay, and photos load without the brief stutter some users noticed on iOS 26.

There are also fixes under the hood for how iMessage syncs across devices. Messages that previously failed silently now retry automatically, and conversations stay better aligned between an iPhone, iPad, and Mac. Switching between Wi-Fi and cellular is smoother too, which matters for anyone who spends the day moving between office Wi-Fi, a data plan, and public networks. The best part is that none of this depends on Apple Intelligence, so even an iPhone 11 or iPhone 12 benefits.

2. Siri AI: The Assistant Apple Should Have Shipped Years Ago

This is the feature carrying the whole release. Siri AI replaces the assistant iPhone owners have quietly tolerated for over a decade with something built for back-and-forth conversation, closer in spirit to ChatGPT or Claude than to the old command-and-response Siri.

The difference is not just tone. Siri AI can dig into your messages, emails, photos, and installed apps because it has private access to your personal data, which lets it complete tasks that used to require opening three different apps. Ask it to find every email a particular colleague sent you last month, and it will surface them. Tell it to build a home automation that locks the doors at midnight, and it sets it up without you touching the Home app. It can search the open web for general questions, pull passwords stored in the Passwords app when you ask, delete a batch of old screenshots, or add a shopping list built entirely from a recipe link you found online.

You can talk to it in several ways: say a wake word, swipe down from the middle of the screen to type a question, open the dedicated Siri app, or hold the side button. Apple has confirmed that Siri AI’s rollout will happen in stages by language and region, with the English-language beta still expanding as of the September launch, and full availability in the EU and China delayed for regulatory reasons. Hardware matters too. The full conversational experience needs at least an iPhone 15 Pro, and Apple has reserved features like custom Siri voices for the newer A19 Pro chip found in the iPhone 17 Pro, iPhone Air, and iPhone Duo.

3. Visual Intelligence Moves Into the Camera App

Point your camera at something and Siri can now tell you what it is looking at. Visual Intelligence has been folded directly into the Camera app as a new mode you swipe to, sitting alongside Photo and Video.

Aim it at a plate of food and it will estimate nutritional information. Snap a photo of a restaurant receipt and ask Siri to split it, and it will work out what each person owes. Point it at a flyer, a product on a shelf, or a landmark, and Siri can pull up relevant details without you typing a single word. It is a natural extension of the camera-as-search-bar idea Apple has been building toward for a few years, and it finally feels complete.

4. Write With Siri Lands System-Wide

Apple has added a genuine AI writing assistant that lives in the keyboard, available in almost any app that accepts text input. Highlight a paragraph in Notes, Mail, or a messaging app, and Write with Siri can rewrite it, adjust the tone, tighten the wording, or draft something from a rough idea.

The more interesting trick is that it can study your own past emails and messages to mimic your writing style, so a drafted reply sounds like something you would actually send rather than generic AI copy. Spelling and grammar suggestions are sharper too, catching phrasing issues that the old autocorrect engine used to miss entirely.

5. Photos Gets a Genuinely Useful Clean Up Tool

The Clean Up feature that strips unwanted objects out of photos has been in iOS since last year, but iOS 27 makes it dramatically better at filling in the gaps left behind. Remove a stranger walking through the background of a beach photo, and the tool now blends the replacement pixels convincingly instead of leaving a smudged patch.

Two new tools join it: Extend, which uses AI to stretch the borders of a photo beyond its original frame, and Reframe, which can shift the composition or perspective of an image after the fact. Together they turn Photos into something closer to a lightweight editing suite than a simple gallery app.

6. Adjustable Liquid Glass, Finally With a Slider

Liquid Glass, the translucent design language Apple introduced with iOS 26, split opinion. Some loved the glassy look on buttons and toolbars; others found it distracting or hard to read in bright sunlight. iOS 27 settles the argument by giving users control. Head to Settings, then Appearance, then Liquid Glass, and a new slider lets you dial the transparency up or down until the interface looks the way you want it. It is a small addition, but it is the fix a lot of users have been asking for since last year.

7. Safari Learns to Build Its Own Extensions

Safari’s AI upgrades are aimed squarely at power users. You can now describe what you want a webpage to do in plain English, and Safari will generate a custom browser extension on the spot. Apple’s own examples include creating a citation for the page you are on, building a three-minute focus timer, forcing a minimum font size, or even restyling a site to look like it belongs in the 1990s.

Beyond extensions, Safari now automatically groups open tabs into topics, which helps if you are the type of person with forty tabs open at once, and it can monitor a page and alert you when something on it changes, handy for tracking price drops or job listings.

8. The Home App Gets Sharper Eyes

Owners of HomeKit Secure Video cameras get two solid upgrades. Recording quality jumps to 2K and 4K, and a new AI layer can describe, in plain text, what just happened on camera, then let you search through footage using natural language rather than scrubbing through a timeline manually. Ask “show me when the delivery driver came” and the Home app will pull up the relevant clip.

The catch is that the AI description and search features require a 2TB iCloud+ subscription for a single camera, with higher-tier plans needed to cover more cameras. The 4K streaming itself, however, does not require the storage upgrade.

9. Custom Sound Tuning for AirPods

If the default AirPods sound profile has never quite matched your taste, iOS 27 introduces a proper EQ. You can now adjust bass, mids, and highs directly from the Bluetooth settings, tuning the sound the way you would on a dedicated music app. The feature covers AirPods 4, AirPods Pro 2, AirPods Pro 3, and AirPods Max 2, so it is worth checking your model before getting your hopes up.

10. Shortcuts Without the Headache

The Shortcuts app has always been powerful and consistently intimidating for casual users. iOS 27 changes that by letting you describe, in ordinary language, what you want a shortcut to accomplish. Siri then builds it for you, and you can refine the result with further natural-language instructions or drop into the manual editor if you want full control. It is the kind of change that should finally get more people automating small daily tasks instead of avoiding the app altogether.

Which iPhones Actually Support iOS 27?

Compatibility is more layered this year than usual, since the headline AI features need considerably newer hardware than the update itself.

In practice, this means older iPhones going back to the iPhone 11 will install the update and feel the performance boost, but the marquee AI features stay locked to the iPhone 15 Pro generation and later. Owners of the base iPhone 15 or older Pro models without Apple Intelligence support will still get the interface refinements and the adjustable Liquid Glass slider, just without the conversational Siri experience.

How to Install iOS 27

Updating is the same process as always. Open Settings, tap General, then Software Update, and the iOS 27 download should appear if your device qualifies. Apple typically stages the rollout, so it is normal for the update to show up for some users a few hours before others on launch day. Backing up your iPhone beforehand, either through iCloud or a computer, is still good practice before any major iOS update.

iOS 27 is less about a single flashy feature and more about Apple finally catching its AI ambitions up to what users have wanted for a while. Siri AI is the obvious headline, but the quieter wins, faster performance across the board, a Liquid Glass slider, sharper Photos editing, and a friendlier Shortcuts app, are what most people will actually notice day to day. If your iPhone supports it, this is one of the more worthwhile updates Apple has shipped in recent memory.
