Every year, Apple updates its iPhone software, and these updates are known as iOS. Presently, several iPhones are running iOS 17 or 18, but rumor has it that a big change is coming this time, one that is likely to involve changing the name of iOS.

Expected Name of the New Software that Will Run on iPhone Insted of iOS
Some sources say that the next iPhone software update may be dubbed 'iPhoneOS', the term Apple had used when it inaugurated the device in 2007. After that, it was changed to "iOS", and the old name may find itself back in use.
The Name of Other Software Used by Apple for Its Devices
One of the reasons for this change may be that Apple now has different OS or operating systems for different devices like iPadOS (for iPads), watchOS (for Apple Watches), tvOS (for Apple TVs), and so on. This might make the iPhone's name 'iPhoneOS' seem like a more appropriate and completely different identity altogether.
Tech industry analysts are increasingly surfacing discussions regarding this possible Apple change. Nevertheless, no action has yet been taken on it. It may debut such information in June next year at WWDC 2025 (Apple Developer Event).
Other Updates Include
This would be exciting news for iPhone users because, other than the name, new updates have a lot of hearsay regarding them, full of new features. Certainly, be it iOS or iPhoneOS, Apple has always been out there in pursuit of getting their software updates loaded with features on security and speed, complemented with cutting-edge technology.

Bloomberg’s Mark Claims
According to Bloomberg’s Mark, Apple might switch to year-based names, which means the iPhone software update we are expecting is iOS 19, after iOS 18. It would be iOS 26 instead of 19, because of the year 2026.
Thus, for all iPhone owners, be prepared for some forthcoming innovations. Only time shall tell what changes will come to be affirmed by Apple.
