Determining device compatibility with Apple’s iOS 18 centers on understanding the expected lifecycle support for existing iPhone models. This involves assessing which generations of iPhones possess the processing power and architecture necessary to run the updated operating system efficiently. For example, previous iOS updates have typically excluded older models lacking certain hardware capabilities.
Identifying compatible devices carries significant implications for users. It determines whether an individual will have access to the latest features, security updates, and performance improvements that iOS 18 will introduce. Historically, continued software support has been a crucial factor in maintaining device security and prolonging the usable lifespan of an iPhone.
