iPhone 18 models may lack advanced Siri AI features due to memory limits

The upcoming iPhone 18, slated for a spring 2027 release, may not support all of Apple's advanced Siri AI features due to memory limitations. While the standard iPhone 18 and its budget variant, the iPhone 18e, are expected to have 9GB of DRAM, this is reportedly insufficient for features like expressive Siri voices and enhanced dictation. These advanced capabilities are reserved for models with 12GB of RAM, such as the iPhone 18 Pro, iPhone 18 Pro Max, and the rumored iPhone Ultra, which are scheduled for a September release. AI
