The process involves installing a newer version of the software that powers Apple’s mobile devices, such as iPhones and iPads. This installation replaces the existing system software with a more current iteration. For example, moving a device from iOS 16 to iOS 17 constitutes such a change.
Applying these revisions is critical for device security and functionality. They often include patches for vulnerabilities, protecting against potential threats. Furthermore, they can introduce new features, enhance existing performance, and improve battery management. Historically, these revisions were infrequent and required a wired connection; modern iterations are typically delivered over-the-air (OTA), streamlining the user experience.
