The standard iPhone 18 might not include two significant Siri AI functionalities.

      The standard iPhone 18 may lack sufficient RAM to support certain AI features locally.

      Apple is anticipated to introduce the iPhone 18 Pro and iPhone 18 Pro Max this fall, potentially alongside its first foldable iPhone. In contrast, the standard iPhone 18 is expected to launch in spring 2027, alongside the iPhone 18e. Although the lineup is projected to increase RAM, this upgrade may still not meet the requirements for two advanced Siri AI functionalities in the standard and 18e models.

      The challenge lies with Apple’s AFM Core Advanced model, which facilitates Advanced Dictation Preview in iOS 27 and the new expressive Siri voices. This model operates locally on compatible devices but necessitates a minimum of 12GB of RAM.

      More memory may not suffice

      According to TF International Securities analyst Ming-Chi Kuo, Apple's entry-level iPhones in 2027, powered by the A20 chip, will increase to 9GB of RAM from the current 8GB on standard models. Forbes indicates that this enhancement might still leave the iPhone 18 and iPhone 18e lacking the necessary RAM for Apple’s more advanced Siri features.

      iOS 27 is set to provide tighter system-level integration with Apple Intelligence. My recent industry observations suggest that Apple’s lower-end iPhones expected in the first half of 2027, equipped with the A20 chip, will shift to 9GB DRAM (1.5GB × 6 dies), up from 8GB (2GB × 4 dies) in the existing A19 models, to sustain the system… — Ming-Chi Kuo (@mingchikuo) June 26, 2026

      Currently, Advanced Dictation Preview is accessible on the iPhone 17 Pro, iPhone 17 Pro Max, and iPhone Air utilizing the iOS 27 beta, while the standard iPhone 17 and even the iPhone 16 Pro are excluded due to their 8GB RAM.

      Advanced Dictation Preview enhances accuracy and can autonomously manage punctuation and capitalization as users speak. The expressive Siri voices are aimed at making Apple's assistant sound more natural and adaptable. If the 12GB benchmark remains, these features will be unavailable on the standard 18 and 18e models.

      The Pro models are expected to excel

      Apple has yet to unveil the iPhone 18 lineup, so the division of features remains unconfirmed. Kuo states that the iPhone 18 Pro, iPhone 18 Pro Max, and the anticipated foldable iPhone will maintain 12GB of RAM.

      This differentiation might suggest that Apple is nudging consumers towards the Pro models; however, the RAM situation is more nuanced than simple product categorization. Apple has already increased prices across its iPad and Mac product lines as RAM costs have risen, and the upcoming iPhone 18 Pro models are likely to experience a price surge of approximately $200.

      The company is reportedly also seeking governmental approval to procure RAM from China’s CXMT as it manages a supply shortage that is complicating the integration of advanced AI features in more affordable models.

      Apple’s foldable iPhone may be introduced this fall, but acquiring one could be challenging.

      There might be a launch shortage for Apple's foldable iPhone.

      Reports from industry analyst Ming-Chi Kuo suggest that the anticipated iPhone Ultra (foldable iPhone) may be announced alongside the iPhone 18 Pro and iPhone 18 Pro Max, but preorders and sales might occur later due to expected limited early production. Kuo estimates that Apple could produce approximately 7 million to 8 million foldable iPhones in the latter half of 2026, but only 0.5 million to 1 million units might be ready by the third quarter, a critical period when Apple typically prepares for its September iPhone launch. In contrast, the iPhone 18 Pro and Pro Max are expected to have around 20 million to 22 million units available during the same timeframe.

      Apple is anticipated to unveil three new iPhones this fall, including the iPhone 18 Pro, iPhone 18 Pro Max, and the rumored foldable iPhone Ultra. Recent leaks suggest that the iPhone 18 Pro Max will experience a significant battery enhancement, with one source claiming a 5,235mAh battery for the physical SIM variant and a 5,425mAh battery for the eSIM-only version. Additionally, China's 3C certification database (via Digital Chat Station) appears to indicate the actual battery capacities for both the iPhone 18 Pro and iPhone 18 Pro Max, with the Pro Max figures revealed as even larger than previous leaks suggested.

      iOS 27 has finally introduced a much-improved Siri experience for iPhones, meeting the expectations Apple set three years ago. The new Siri, referred to as Siri
