On June 8, 2026, Apple revealed the details of its next generation of iPhone software at its Worldwide Developers Conference in Cupertino, California. It was Tim Cook’s last WWDC as Apple CEO before he steps down from the role, and the event’s announcements included new developments in Siri AI, Apple Intelligence and Liquid Glass software design.

The unifying thread connecting all of WWDC 2026’s announcements was iOS 27, Apple’s latest operating system update. Reportedly optimised for the arrival of Apple’s first foldable iPhones in September, according to sources like Bloomberg, iOS 27 is set to enhance your iPhone’s AI features, digital tools and shortcuts.


Despite its many benefits, iOS 27 has a significant downside for older iPhone users: not every iPhone will support it. If your iPhone has more than a few years behind it, there’s a high chance you’ll miss out on important security updates and new software features going forward.

Buying a refurbished iPhone is the best way to balance software longevity, cost savings and performance all at once without compromising on any of them. OzMobiles is Australia’s leading refurbished smartphone destination, with a wide range of locally-sourced and high-quality refurbished iPhones. If you’re wondering if your current iPhone is iOS upgrade-ready and why you should buy a refurbished model, the OzMobiles team can answer all your questions. Here’s our guide to iOS 27 and the most effective way to maintain iOS capability: refurbished smartphones. 

The Big Reveal: What the Latest Software Updates Mean for Your iPhone and Why iOS 27 Matters

iOS is Apple’s sleek, intuitive operating system that runs on each of its digital devices in order to create a seamless experience. It’s the software that makes Apple’s ecosystem, which includes iPhones, iPads, Macs and Apple Watches, operate so smoothly in sync. Every year, Apple unveils the new version of iOS during its WWDC event in June before the final version is released with September’s new iPhone models.

At WWDC 2026, the latest update was announced during the opening keynote at 10 a.m. PT/1 p.m. ET and then released in beta mode for developers. In July, an iOS 27 public beta will allow iPhone users to test new features and offer their feedback, with the final version becoming available to the general public in September, along with the new iPhone line-up.  

If the big question on your mind is “will my iPhone support iOS 27?”, here’s some good news. Apple hasn’t dropped any devices from the update cycle. If your device is an iPhone 11 or newer model, you’ll be able to take advantage of iOS 27. 

If your iPhone is iOS 27 compatible, here is what the latest updates mean for you:

Greater stability and performance

Apple’s main focus for iOS 27 will reportedly be ironing out issues and enhancing the overall quality of performance, according to sources like Macworld. This means Apple’s engineers have been fixing bugs and cutting bloating wherever possible.

Foldable functionality

In September, Apple launches its first foldable iPhone, which, according to rumours, is expected to feature a 7.8-inch inner display and a 5.5-inch outer display. iOS 27 will optimise Apple’s software for this new model, with new features and app layouts that take advantage of the larger screen size.

Apple Intelligence

Having made a deal with Google, Apple will reportedly use the search engine’s Gemini models to power iOS 27’s Siri and Apple Intelligence features. According to Bloomberg, Siri will live inside the Dynamic Island and feature a ‘Search or Ask’ interface that you’ll be able to scroll down from the top of the screen to access. A standalone Siri chatbot app will let you auto-delete chats or upload files and photos with your voice. New writing tools and features include a ‘Help Me Write’ button, a ‘Write with Siri’ toggle and a powerful grammar checker to rival Grammarly.

A fully customisable camera app

Apple is continuing to enhance the iPhone’s camera app after iOS 26’s dramatic overhaul. Additions include Visual Intelligence that recognises labels and contact information, and an Add Widgets function that lets you decide which features appear in the camera app interface and wear.

New photo editing features

Apple will reportedly add three new photo editing features that let you get creative with the images you capture. ‘Extend’ allows users to generate extra image content beyond the image’s original frame, ‘Enhance’ improves an image’s quality, while ‘Reframe’ allows users to shift perspective. The ‘Clean Up’ feature that already exists in the app also has improvements in the works

The Official iOS 27 Compatibility List: Which Models Make the Cut?

One of the most persistent rumours leading up to WWDC 2026 was that Apple would drop support for the iPhone 11 range and older models. Legend had it that the iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max and iPhone SE (2nd generation) would lose protection.

Fortunately, the rumours were wrong on this count as Apple made a point of announcing during WWDC that your iPhone 11 model will indeed be able to install iOS 27. The caveat is that you won’t be able to use anything older than an iPhone 15 Pro / Pro Max if you want to use the new Apple Intelligence features, such as Siri AI.

The full list of models that support iOS 27 includes:

(use check icons as bullet point symbol)

  • iPhone SE (2nd generation and later)

  •  iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max

  • iPhone 12 Mini, iPhone 12, iPhone 12 Pro, iPhone 12 Pro Max

  • iPhone 13 Mini, iPhone 13, iPhone 13 Pro and iPhone 13 Pro Max

  • iPhone 14, iPhone 14 Plus, iPhone 14 Pro and iPhone 14 Pro Max

  • iPhone 15, iPhone 15 Plus, iPhone 15 Pro and iPhone 15 Pro Max

  • iPhone 16e, iPhone 16, iPhone 16 Pro and iPhone 16 Pro Max

  • iPhone 17e, iPhone 17, iPhone Air, iPhone 17 Pro and iPhone 17 Pro Max

If you have an older model iPhone than the iPhone 11, the reality is that you will not be getting iOS 27. However, that doesn’t mean your iPhone will stop working, simply that you won’t get any new apps, design upgrades, AI features or (eventually) new security measures. 

Unlocking Premium Features without the Premium Price Tag 

Every time Apple releases a new iPhone line-up, they push the boundaries of what is possible in terms of design, processing power, software, battery life and (lately) generative AI. While iPhones remain consistently popular, many buyers are put off buying the latest models due to the cost. 

If you know your iPhone model, it’s easy to cross-check it with the compatibility list in this and other articles. To check that you’re using the latest version of iOS, go to Settings > General > Software Update, and if an update is available for your device, select Update Now. 

If you’ve been looking to upgrade your iPhone and want to make sure you choose one that’s iOS 27 compatible, the refurbished iPhone market offers newer models at more affordable prices. 

Refurbished smartphones are pre-owned phones that qualified professionals have put through a detailed inspection and repair process and restored to full working order. While a used phone is sold, usually without a warranty, in the condition the previous owner left it, a refurbished smartphone has been cleaned, tested and fixed up to meet high Australian standards and comes with a warranty and other guarantees included. Often, the only difference you’ll find between a refurbished smartphone and a new one is some superficial markings or blemishes.

Refurbished smartphones are a positive option for both the planet and your bank balance, reducing your carbon footprint and saving you hundreds of dollars.

iPhones are extremely common and popular on the refurbished market, and you don’t have to settle for an ancient model when you buy one. When a new iPhone hits the stores, many Apple enthusiasts race out to upgrade their existing models, leading to models that may only be a year or two old arriving on the refurbished market. You’ll also find plenty of ex-demo iPhones that have only been removed from their boxes to be displayed in-store. 

Step Up to Modern Performance with a Smart Hardware Upgrade

If your iPhone is ageing and won’t be able to support the latest iOS upgrade, buying a refurbished iPhone is one of the easiest and most powerful hardware upgrades you can make. Buying a refurbished iPhone 15, a refurbished iPhone 14 or even an older model means a dramatic discount from the original sale price with full access to new protections and features.

Enjoy Next Generation Performance with an iPhone 15 Refurbished Model

The iPhone 15’s main claim to fame was being the first phone on which Apple embraced USB-C charging instead of Lightning. But there’s more to this handset than that. Released in 2023, the iPhone 15 remains a highly practical and dynamic all-rounder. Powered by the A16 Bionic chip, it has a camera that takes incredibly vibrant photographs and a battery with up to 20 hours of video playback. Now that it’s been on the second-hand market for a couple of years, you can experience a refurbished iPhone 15’s incredible next-generation performance while striking hundreds of dollars off the price.

Save Big and Stay Connected with an iPhone 14 Refurbished Handset

The savings get even better when you pick up an iPhone 14 refurbished. Released in 2022, the iPhone 14 still provides a reliable and high-performing device for everyday tasks. While you still need to buy the Pro or Pro Max models for features like Dynamic Island, the base model iPhone 14 still has a capable camera set-up, a 15+ hour battery life and a subtle yet elegant design. 

How the Refurbished Smartphone Market Compares to Buying Retail Alternatives

Brand new phones from brands like Apple and Samsung come direct from the factory in pristine condition, but with a price tag that many find unaffordable. Customers want value for money without compromising on quality, and a refurbished smartphone is the most effective way to get it. While new phones are expensive, used phones come with a host of risks: badly degraded batteries, hidden water damage, and a locked carrier. Many used smartphones are sold without warranties, and some may even be stolen.

Compared to other retail options, refurbished smartphones have several unique benefits, including:

Cost savings

With savings of up to 50-70% on some models, there’s simply no better option than refurbished smartphones when you want to save money but still take home a good product. You can own premium flagship phones that would usually extend your budget while staying well within it.

Rigorous testing

Refurbished smartphones are the most extensively tested second-hand smartphones on the market, professionally inspected in order to meet high Australian sales standards.

Warranty

Unlike most used phones, refurbished smartphones almost always come with warranties included.

Freedom of carrier

Refurbished smartphones are sold unlocked so that you can instantly make them your own without worrying about previous carriers. Just pop your SIM card in and you’re ready to go.

Better for the environment

Refurbished smartphones help the environment in two ways. On top of reducing the amount of e-waste that ends up in Australia’s landfills, they remove the need for carbon emissions and more raw materials to be involved in the production of a new smartphone.

The official launch of iOS 27 drops major software support for generations older than the iPhone 11 series, meaning legacy models like the iPhone X, XR, and XS will no longer receive operating system updates. If your current phone is left off the official list, upgrading to a certified refurbished iPhone is an efficient way to regain modern software longevity without paying full retail costs.

Yes, unsupported devices will continue to handle basic daily tasks like calls, texts, and web browsing. However, as time goes on, your device will stop receiving critical Apple security patches and new app updates, making your personal data more vulnerable over time. Transitioning to a supported model, such as an iPhone 14 refurbished handset, ensures your operating system remains fully secure and protected.

An iPhone 15 refurbished base model fully supports the core performance optimisations, layout updates, and camera enhancements introduced in the new software. However, Apple's advanced, on-device Apple Intelligence system and Siri AI updates are restricted to the iPhone 15 Pro, Pro Max, and newer models due to the specific processing memory required for on-device AI.

Historical trends and lifecycle data of previous device generations show that Apple typically provides major operating system updates for roughly six to seven years from a model's original launch date. This extensive support window means that investing in a relatively recent refurbished model ensures you will receive multiple years of ongoing digital security and functional utility.

Apple has explicitly optimised the core architecture of iOS 27 to clean up system bloating and improve operational stability across older compatible hardware. However, major updates can strain older internal components if your battery health is degraded. If a supported phone feels sluggish after an update, replacing the battery is often the most effective way to restore its peak performance speeds.
