Apple typically releases its new iOS version alongside new iPhone launches in September, ensuring the latest iOS (e.g., iOS 19 in 2025) ships on new models like the iPhone 17 series out of the box. For older iPhone models, the update is usually available for download on the same day or within a day or two of the new iPhones hitting stores, assuming the older device is compatible. There’s no significant delay for supported models—Apple rolls out the update universally across eligible devices via OTA (over-the-air) updates. Compatibility usually extends to iPhones from the past 5-6 years, though some features may be exclusive to newer hardware.
