iOS 18.3 update rolls out, but not all devices can access new features

In the UK, Apple released its iOS 18.3 update, enabling several devices to benefit from new features, including advancements in Apple Intelligence. This update follows the earlier iOS 18.2 release, which had already introduced initial capabilities. The update requires an iPhone to have an A12 Bionic chip or later, ensuring that the devices are equipped with sufficient processing power to handle the enhanced AI functionalities. However, while many iPhones are capable of upgrading, only specific models, including the iPhone 15 Pro, iPhone 15 Pro Max, and the entire iPhone 16 line-up, are eligible to utilize the advanced Apple Intelligence features, which provide users with visual intelligence capabilities. For users with older models, features such as phone call recording and natural language search functionality are still included, although they are unable to access the full suite of Apple Intelligence capabilities. As a result, the upgrade experience differs significantly between users with newer and older devices, which may create a disparity in user satisfaction regarding the latest iOS developments. The release reflects Apple's ongoing efforts to improve user experience and functionality across its devices while imposing hardware limitations that determine the availability of certain cutting-edge features.
