Apple has confirmed that iOS 18 will be available for all iPhones currently supported by iOS 17, ensuring that millions of users can enjoy the latest software update. However, there’s a catch—most of the headline AI-powered features, collectively known as Apple Intelligence, won’t be available on older iPhone models due to hardware limitations.
While iOS 18 introduces a host of customization options and productivity improvements across the board, Apple’s new AI capabilities will be reserved for only a select group of devices.
iOS 18 Supported iPhones
Apple has confirmed that iOS 18 will support the following iPhone models:
- iPhone XS and iPhone XS Max
- iPhone XR
- iPhone 11, 11 Pro, and 11 Pro Max
- iPhone SE (2nd generation)
- iPhone 12, 12 mini, 12 Pro, and 12 Pro Max
- iPhone 13, 13 mini, 13 Pro, and 13 Pro Max
- iPhone SE (3rd generation)
- iPhone 14, 14 Plus, 14 Pro, and 14 Pro Max
- iPhone 15 and iPhone 15 Plus
- iPhone 15 Pro and iPhone 15 Pro Max
This means users with an iPhone powered by the A12 Bionic chip or newer can install iOS 18.
Apple Intelligence Is Limited to the iPhone 15 Pro Models
Although every supported iPhone will receive iOS 18, Apple Intelligence will initially be available only on:
- iPhone 15 Pro
- iPhone 15 Pro Max
Apple says the AI platform requires the A17 Pro chip and its more powerful Neural Engine, along with additional memory, to run advanced on-device AI models efficiently.
This means even relatively new devices like the iPhone 15, iPhone 14 Pro, and iPhone 13 Pro will not support Apple Intelligence.
What Older iPhones Still Get
Even without Apple Intelligence, iOS 18 brings several major upgrades to all compatible iPhones, including:
- Home Screen customization with app icon tinting
- Redesigned Control Center
- Lock and hide apps for better privacy
- Enhanced Messages with new text effects and scheduling
- Improvements to the Photos app
- Passwords app for managing credentials
- Better Safari browsing experience
- Game Mode for improved gaming performance
- Updated Wallet and Mail features
These additions ensure that older iPhones still receive a meaningful software upgrade despite missing the AI features.
Apple Intelligence Features
Compatible devices will gain access to a suite of AI-powered capabilities, such as:
- Writing Tools for rewriting, proofreading, and summarizing text
- Image Playground for AI-generated images
- Genmoji to create custom emojis
- Smarter Siri with deeper app integration
- AI-powered notification summaries
- Priority Messages and Smart Reply
- Clean Up tool for removing unwanted objects from photos
- Integration with ChatGPT for more advanced assistance when needed
Apple emphasizes that many of these features run on-device to enhance privacy, while more complex requests are handled through Private Cloud Compute.
Why the Hardware Restriction?
Apple explains that Apple Intelligence relies on large on-device AI models that require significant processing power and memory. The A17 Pro chip found in the iPhone 15 Pro models includes a faster Neural Engine capable of handling these demanding AI workloads while maintaining performance and battery efficiency.
Final Thoughts
With iOS 18, Apple is ensuring that every currently supported iPhone continues to receive the latest operating system, reinforcing its reputation for long-term software support. However, the company’s most ambitious AI features are exclusive to the iPhone 15 Pro and iPhone 15 Pro Max, leaving the majority of existing iPhone users without access to Apple Intelligence.
Even so, iOS 18 delivers numerous quality-of-life improvements, new customization options, and enhanced privacy features, making it a worthwhile update for all compatible iPhone owners.
