MacRumors reported that the standard iPhone 18 models might feature 9GB of RAM, which could be insufficient for high-end iOS 27 capabilities requiring 12GB.
According to reporting from MacRumors, upcoming iPhone 18 and 18e variants are expected to include a RAM upgrade that still falls short of certain advanced Apple Intelligence requirements.
If these hardware limitations occur, users on entry-level models may face feature gaps in Siri's voice customization and dictation accuracy compared to Pro devices.
The information is attributed to a reputable supply chain analyst via a well-known Apple news outlet.

“iPhone 18 With 9GB RAM Still Won't Support Two New iOS 27 Features Friday July 3, 2026 12:10 pm PDT by Joe Rossignol The lower-end iPhone 18 and iPhone 18e will be equipped with 9G”

MacRumors reported that analyst Jeff Pu expects Apple’s iPhone 18e to ship with 9GB of RAM, up from the iPhone 17e’s 8GB. The outlet noted that Ming-Chi Kuo had already floated the same memory figure.
MacRumors reported that code spotted in iOS 27 beta 5 appears to point to six iPhone models tied to Apple’s next iPhone lineup. The outlet says the references line up with previously seen internal identifiers for devices such as iPhone 18 Pro, iPhone Ultra, and iPhone 18e.
MacRumors reported that Apple’s annual iPhone event is expected in the first half of September, with the iPhone 18 Pro, iPhone 18 Pro Max, and a foldable iPhone reportedly called iPhone Ultra on deck. The outlet said a date immediately after Labor Day looks unlikely, and pointed to a later September window instead.
The Verge wrote that a supplier earnings call backs reports that Apple will keep the Pro iPhone 18 models on a fall timeline while the standard model slips to next year. The story also notes that an iPhone 18e and a new iPhone Air are being discussed for a later launch window.
