The iPhone 18 is expected to feature 12GB RAM, up from 8GB on the base iPhone 17.
The RAM upgrade is tipped to support Apple's advanced on-device AI features and enhanced Siri.
Apple may launch the iPhone 18 alongside the iPhone 18e in spring 2027 while keeping the price unchanged.
Apple is skipping the launch of the iPhone 18 this year, and it will likely be announced alongside the iPhone 18e early next year. However, reports suggest that the upcoming iPhone 18 will feature 12GB of RAM, instead of the 8GB RAM seen on the base iPhone 17, to support the company's most advanced on-device AI features and enhanced Siri functionality while keeping its price unchanged. Here are the expected details of the iPhone 18.
According to a report by DigiTimes, the tech giant will equip the base iPhone 18 with 12GB RAM. This increase is driven by the requirements of the enhanced Siri AI model, which was announced at WWDC 2026.
The advanced Siri features, including more expressive voices and major improvements in systemwide dictation accuracy, need 12GB of unified memory to function at full capacity.
While the iPhone 17 base model was limited to the less powerful Siri version due to its 8GB RAM, the iPhone 18 is expected to bring these premium AI capabilities to the standard model without any price increase, likely remaining at USD 799.
Citing the latest report, MacRumors reports that the tech giant has instructed its suppliers to ramp up production of LPDDR5X RAM chips for the next iPhone series.
According to KB Securities, Apple will continue purchasing mobile DRAM from Samsung, SK Hynix, and Micron at premium prices above market rates and is likely to absorb these additional costs rather than increasing the phone's price.
Till last year, Apple used to announce the base models alongside the Pro variants in the fall. Meanwhile, the budget-friendly e-models were announced in the spring, but this may be changing.
Reports suggest that the iPhone 18 might launch alongside the iPhone 18e in spring 2027, while the September fall launch event will be reserved for the iPhone 18 Pro and iPhone 18 Pro Max variants.
Though not confirmed, the company may be moving to a split launch strategy for the iPhone 18 series mainly due to increasing manufacturing complexity and supply chain challenges.
The iPhone 18 specifications are expected to include a 6.3-inch 120Hz ProMotion OLED panel using an older M12+ OLED material with a smaller Dynamic Island. However, it is not confirmed yet.
The upcoming iPhone 18 will likely be powered by the A20 chip built on a 2nm process, paired with 12GB RAM.
It is expected to come with a 48MP main camera and a 48MP ultrawide sensor with no variable aperture, and an upgraded 24MP front camera.
The iPhone 18 features might include a simplified Camera Control button, with the overall focus on strong AI capabilities and long-term performance optimisation.
Looking at the leaked specifications, we can say that the features of the iPhone 18 largely remain the same as its predecessor. However, it is worth noting that these details are based on speculation and tips, and the company is yet to reveal details regarding the upcoming iPhone 18 and other models. We suggest you take these details with a pinch of salt. Stay tuned for more updates.
