Apple's iOS 18 release date is September 16 but is your iPhone compatible? Here are the eligible devices and new features to expect

In just three days, you'll be able to download iOS 18 on your eligible iPhone. Apple announced the release date at its iPhone event on Monday, along with the new iPhone 16 and iPhone 16 Pro models, and the new Apple Watch Series 10 and AirPods 4 devices (here's everything Apple revealed at the iPhone 16 launch event). If you're lucky enough to snag one of the new phones on September 20, they'll already have iOS 18 installed. But if you're sticking with your older iPhone, you can check out iOS 18 when it becomes available as a free download on September 16. Not every iPhone, however, will be able to run iOS 18, and even the ones that can won't have all the bells and whistles of the new Apple Intelligence features.

That update stratification is nothing now. Generally each year, some older iPhone models are removed from Apple's iOS eligibility list. Last year, for instance, the iPhone 8, iPhone 8 Plus and iPhone X were left off the compatibility list. That meant those iPhone owners couldn't update to iOS 17 and missed out on some notable features. On the flip side, some older hardware will get major new features: Consider the upcoming software update that effectively turns existing AirPods Pro headphones into a hearing aid, complete with a built-in hearing test. (Apple just received FDA approval to release that feature later this year.)

We'll help you find out if your iPhone will support iOS 18, as well as Apple Intelligence. If you want a full list of all the new iOS 18, check out Apple's exhaustive list in PDF form (via MacRumors).

iPhones compatible with iOS 18

We have good news: If you had an eligible phone last year when you updated to iOS 17, that device should still be compatible with iOS 18, according to Apple. That means you won't have to buy a new phone to check out most of the new software features.

• iPhone SE (second generation or later)

• iPhone XR

• iPhone XS

• iPhone XS Max

• iPhone 11

• iPhone 11 Pro

• iPhone 11 Pro Max

• iPhone 12

• iPhone 12 mini

Put another way, if you have an iPhone from the 2017 model year or earlier (iPhone 8 or iPhone X), you can't upgrade to the latest iOS, but your phone should continue to work — albeit without the latest and greatest features.

Is your iPhone compatible with Apple Intelligence?

While your older device will still be able to support the latest iOS, chances are that you won't get to try the Apple Intelligence beta yet next month. Unless you have an iPhone 15 Pro or iPhone 15 Pro Max — the top-end 2023 models — or one of the new iPhone 16 models, your iPhone isn't eligible.

When will Apple Intelligence features be available?

If your device is compatible with Apple Intelligence, you can start playing with some of those features in October, when they begin to hit those newer iPhones in subsequent updates.

Apple Intelligence will be available in English in the US this October. In December, it'll become available in localized English to Australia, Canada, New Zealand, South Africa and the United Kingdom. Additional language support, including Chinese, French, Japanese and Spanish, will be available sometime next year, Apple says.

As previously reported, Apple Intelligence will not be making its way to EU countries anytime soon. The American tech giant remains locked in a battle with European regulators over enforcement details of the EU's Digital Markets Act.

iOS 18 new features to expect

While Apple Intelligence is by far the biggest update coming with iOS 18, its features are going to be released more piecemeal over the subsequent few months. And the more advanced features won't be available on older iPhone models aside from the iPhone 15 Pro series. But the rest of the iOS 18 features will hit the handsets listed above. Here are just some of the highlights you can expect when you download Apple's new software later this month.

Passwords app: Securely store all your credentials in one place, including passwords and security alerts that you can access directly in the app. (While this functionality currently exists in Settings, moving it to a new app should make it easier to locate and access.)

Improved Messages app: A new iMessages experience is bringing the option to bold, italicize, underline and strikethrough your text. You'll also be able to add animations to your text messages. The update is also bringing RCS to iPhones to better support Android compatibility.

An organized photos library: The Photos app is getting a redesign, which allows you to create and pin your own collections in the app — think "wedding photos" or "trip to Aruba." It removes the current tabbed bottom and leans into a grid layout. The updated carousel view that was touted at WWDC was removed during the beta process.

Personalized home screen layout: You'll finally get the option to rearrange your apps — for instance, you can leave the middle space open to display your home screen photo, and instead have your apps alone the border of the screen. You can also change the appearance of the apps by tinting them with any color, as well as making the apps larger.

There are plenty of other tweaks and improvements to keystone apps like Maps, Calendar, Safari and more. Check out Cherlynn Low's choices for the best hidden features of iOS 18 and its sibling Apple operating system updates, based on the betas released earlier this year.

Is there an iOS 18 beta?

There is, and you can download it now — so long as you're willing to live with the glitches and challenges of beta software. If you haven't already downloaded it at this point, we'd suggest just waiting for the real deal to be released in just under a week.
