Why Your Current iPhone Isn't Smart Enough for iOS 27

Apple’s iOS 27 supports older devices back to the iPhone 11 thanks to a clever new CPU scheduler, but don't celebrate just yet. The crown jewels of Apple Intelligence—like the ultra-natural Siri—are locked behind a hefty hardware wall. Apple is demanding a whopping twelve gigabytes of RAM for its advanced local AI models. This means you will need an iPhone 17 Pro, Pro Max, or the sleek new iPhone Air to experience them. Even iPad users are feeling the pinch, as these features require an M4 iPad Pro with at least one terabyte of storage, or the new M4 iPad Air. It is the classic Apple RAM tax all over again, proving that while your older device can run the system, the real magic remains a premium privilege.
