Every year, Apple updates its phone lineup with new iPhone models and a new iteration of its accompanying iOS operating system. With the increasing technical demands on iOS, older iPhones are left behind every year, and the upcoming release of iOS 18 is no exception.
Apple is likely to release iOS 18 in June at its annual Worldwide Developers Conference. According to The New York Post, iPhones released before 2018, including iPhone SE and iPhone 8 Plus and earlier, will not be able to upgrade to iOS 18. This is because the software requires more sophisticated hardware and the outdated chips cannot handle some of the new functions.
The upcoming iOS update is expected to be a big shift for Apple as the tech giant is rumored to introduce AI-powered features in iOS 18. It is likely to be highlighted at WWDC, where Apple typically debuts new operating systems for the iPhone, iPad, Mac, Apple Watch and Apple TV.
With Vision Pro now part of the Apple family, it is possible that the company may share some news about the "spatial computing" headset as well. All you need to upgrade your iPhone to iOS 18 is Apple's A12 Bionic chip, first introduced in the iPhone XR and iPhone XS in 2018.
The models since then, including the iPhone 11 to 15 and other generations of the SE, XR, XS and XS Max, all come with this technology built-in. Users of iPhones with the A11 Bionic chip that comes in the iPhone X, 8 and 8 Plus, and the A10 Fusion chip in the iPhone 7 and 7 Plus will be left out of the party.
