Apple Intelligence features in iOS 27.1:

• iPhone 18 Pro or iPhone 18 Pro Max — ONLY these devices

Why Pro only: Custom Voice uses the Neural Engine + 4B LLM to train a personalized voice model. Only the Pro / Pro Max has 12GB RAM to fit the on-device model + trained user voice. The base iPhone 18 has 8GB which is enough for stock Siri 2.0 but not Custom Voice.

How do I check if my device supports iOS 27.1?

Method 1: Settings → General → Software Update

• If iOS 27.1 appears, your device supports it
• If "Your software is up to date" and you're on iOS 26, your device is too old

Method 2: Apple Support page

• Visit support.apple.com/guide/iphone — Apple lists every supported device

Method 3: Apple's iOS 27.1 release notes (Nov 9, 2026)

• Lists every supported device at the top of the release notes

What if my device doesn't support iOS 27.1?

Options if you're on iPhone 15, 14S, or older:

• Stay on iOS 26 — Apple will continue iOS 26 security updates until Dec 2027
• Get a new iPhone — iPhone 17 Pro Max starts at $1,199 with full Apple Intelligence support
• Trade up — Apple's trade-in program gives $200-$600 credit for iPhone 14/15 toward iPhone 17

Security implications of staying on iOS 26: Apple issues security patches for 3 years after a major iOS release. iOS 26 will receive updates through Sept 2028. After that, no more security patches — your device will be vulnerable to new exploits.
