The upcoming operating system for iPhones, iOS 27, is expected to introduce a wide array of new features and significant enhancements for both new and older devices. This update is poised to be Apple's largest of the year, with the company likely to unveil it officially during the WWDC conference scheduled for June 8th. Apple has not yet officially announced the list of iPhone models that will support iOS 27, which is anticipated to include a completely revamped version of the Siri voice assistant in a chatbot-like style, alongside a dedicated application for it. However, recent reports, citing a Chinese leaker account known for its accuracy, suggest it has accessed the official compatibility list. According to revelations from "Instant Digital" via the Chinese platform Weibo, the new generation of "Apple Intelligence" — which will power Siri's enhanced capabilities — requires an iPhone from the iPhone 12 series or newer. This indicates that the following models might be too old to receive the update upon its official launch in mid-September: - iPhone 11 - iPhone 11 Pro - iPhone 11 Pro Max - iPhone SE (2nd Generation) Nevertheless, this does not mean these devices will be entirely deprived of support, as they will continue to receive security updates and other iOS 26 system updates for several years to come. Based on these leaks, the following models are expected to be compatible with iOS 27, including iPhones currently available and those anticipated for future release: - iPhone 17e - iPhone 17 - iPhone 17 Pro and iPhone 17 Pro Max - iPhone Air - iPhone 16e - iPhone 16 - iPhone 16 Plus - iPhone 16 Pro - iPhone 16 Pro Max - iPhone 15 - iPhone 15 Plus - iPhone 15 Pro - iPhone 15 Pro Max - iPhone 14 - iPhone 14 Plus - iPhone 14 Pro - iPhone 14 Pro Max - iPhone 13 - iPhone 13 Mini - iPhone 13 Pro - iPhone 13 Pro Max - iPhone 12 - iPhone 12 Mini - iPhone 12 Pro - iPhone 12 Pro Max - iPhone SE (3rd Generation) The first developer beta of iOS 27 is expected to be released shortly after the presentation concludes during WWDC. This will likely be followed by a public beta in July, before the system is rolled out to all compatible iPhones around mid-September. Although iOS 27 is not anticipated to bring radical changes to the user interface, it could become one of Apple's most significant releases in years. It is expected to integrate "Apple Intelligence" features, announced in June 2024, into the new system, alongside noticeable improvements to the Siri voice assistant, which are said to form a key part of the system update. Apple is also expected to offer broader upgrades to "Apple Intelligence," potentially bringing more intelligence to applications across iPhones, iPads, and Macs. If these reports prove accurate, iOS 27 will focus on making the user experience faster, smoother, and more reliable, while laying the groundwork for Apple's next generation of artificial intelligence features.
