IPhone 18 and 18e Locked Out of Two iOS 27 Apple Intelligence Features
What You Need to Know
- IPhone 18 and 18e receive 9GB RAM, up from 8GB, primarily for Apple Intelligence stability.
- Two iOS 27 Apple Intelligence features require 12GB RAM, excluding iPhone 18 and 18e models.
- Pro models and iPhone Ultra retain exclusive access to advanced local AI capabilities.
- Standard iPhone 18 models launch March 2027, four months after Pro lineup September release.
Apple’s plan to give the iPhone 18 and iPhone 18e 9GB of RAM reads like a modest concession rather than a meaningful upgrade. According to supply chain analyst Ming-Chi Kuo, the bump from 8GB (used in the iPhone 17 and iPhone 17e) is primarily aimed at keeping Apple Intelligence running smoothly on the lower-end models, not at closing the gap with Pro hardware.
The gap, as it turns out, matters more than the upgrade. Two iOS 27 features tied to Apple’s most advanced on-device AI model will require at least 12GB of RAM, which means the iPhone 18 and iPhone 18e are locked out before they even launch. Those two gated features are Siri voice customization (adjustable expressiveness and speaking pace) and a significant accuracy improvement for systemwide speech-to-text dictation.
The full reported RAM breakdown across the iPhone 18 lineup:
- iPhone 18e: 9GB
- iPhone 18: 9GB
- iPhone 18 Pro: 12GB
- iPhone 18 Pro Max: 12GB
- iPhone Ultra: 12GB
- Second-generation iPhone Air: likely 12GB
That split means the Pro lineup and the rumored foldable Ultra retain exclusive access to Apple’s more capable local AI model, continuing a pattern where hardware tiers translate directly into AI feature tiers. Users who want the full iOS 27 Apple Intelligence experience will need to step up to a Pro.
Pricing Pressure Compounds the Divide
Timing adds another layer of complexity. The iPhone 18 Pro, Pro Max, and Ultra are expected in September, while the standard iPhone 18, iPhone 18e, and second-generation Air are not expected until around March 2027. By that point, buyers of the lower-end models will already know exactly which Apple Intelligence features they are giving up.
Component costs are also climbing. RAM and NAND storage shortages have pushed prices up, and analysts expect the iPhone 18 and iPhone 18e to cost $100 to $200 more than their predecessors. Apple has held prices steady so far, but the pressure from supply constraints makes that position harder to sustain with each new cycle.
