A new leak suggests that Apple could significantly upgrade the memory configuration of the upcoming standard iPhone 18. Here’s a look at the latest update.
iPhone 18 To Offer 12GB RAM (Rumour)
According to a fresh report from Taiwan’s Digitimes publication, the next-generation iPhone is expected to arrive with 12GB of RAM. If true, this will mark a notable increase over the 8GB RAM found in the current iPhone 17.
The additional memory is reportedly being introduced to support Apple’s next wave of artificial intelligence features particularly a more advanced version of Siri that relies heavily on on-device AI processing.
This is not the first time the iPhone 18 has been linked to a memory upgrade. Reports about a possible jump to 12GB RAM first surfaced in October 2025, while another source repeated the claim in April this year.
iPhone 18 Could Bring Major Siri AI Enhancements
According to the leak, the upcoming Siri experience will require at least 12GB of RAM to run Apple’s most powerful on-device AI model. As a result, the iPhone 18 is expected to be fully equipped to handle these next-generation AI capabilities.
The upgraded Siri is said to offer more natural and expressive voice options along with new customisation controls that will allow users to fine-tune how the voice assistant sounds. The AI improvements are also expected to deliver significantly better accuracy for system-wide voice dictation.
The advanced Siri features with iOS 27 are expected to roll out in the fall. However, the iPhone 17 may not support these capabilities due to its lower 8GB RAM configuration.
Apple To Absorb Rising Component Costs
One of the more interesting aspects of the latest leak relates to pricing. Memory prices have increased considerably in recent months, which has led many industry observers to expect higher smartphone prices.
However, the report claims Apple could absorb the additional cost of the RAM upgrade rather than passing it on to consumers. If that happens, the iPhone 18 may launch at the same starting price as its predecessor.
According to the leak, the smartphone could retain the $799 starting price in the United States despite the increase in memory capacity.
Expected Launch Timeline
The standard iPhone 18 is currently expected to debut in spring 2027. Apple is also tipped to launch the iPhone 18e and possibly the second-generation iPhone Air alongside it.
Meanwhile, the lineup most likely includes the iPhone 18 Pro, iPhone 18 Pro Max, and the rumoured iPhone Ultra. These are expected to be unveiled earlier with a launch reportedly planned for September.
Notably, Apple has yet to confirm any details regarding the iPhone 18 series.
