Edit: Kinda found a answer
Major versions of iOS are released annually. Apple significantly extended the cycle of updates for iOS-supported devices over the years. Usually, only the latest iOS release is supported by Apple. Starting with iOS 15, Apple started to support 2 major versions of iOS, for a short period of time.
Hi guys this might be a silly question, do ios and iPad OS devices have different number of years of major updates (think ios 16, 17, 18 etc) and years of security updates?
Or do devices that don’t make the cut for the latest major update immediately loose access to security updates once a new incompatible major ios update is released?
Last versions of 15 and 16 both got security updates in 2024. We’ll see if this will change to 16/17 this fall, or if they update 15 still.
