Enough to make you feel you have a brand-new iPhone. Note, though, that one of the biggest things in iOS 18 is the introduction of Apple Intelligence, though it won’t be available in this release. When it arrives, it will be for iPhone 16 series, iPhone 15 Pro and iPhone 15 Pro Max handsets only.

Apple's latest iOS update will be supported by 2018's iPhone XR, iPhone XS, and XS Max models, the oldest smartphones eligible to get the 18th-gen update. Additionally, it is also available from the iPhone SE 2nd Generation from 2020 and the SE 3 from 2022.

After being announced all the way back in June at Apple's WWDC Developers Conference it's now finally time for i OS 18 to be released across the globe. This all-new operating system brings a swathe of improvements to iPhones and also offers a completely new way to customise the look of the home screen - that's a first for Apple!
