Apple Reportedly Dropped 16GB RAM Upgrade for iPhone 18 Pro and Duo Over Soaring Memory Costs

Apple's iPhone 18 Pro and first foldable iPhone Duo will launch with 12GB of RAM, after Apple reportedly dropped earlier internal plans to equip both devices with 16GB as soaring memory prices upended its 2026 hardware roadmap.

The claim comes from Chinese leaker Instant Digital, whose brief Weibo post suggests the higher specification was under consideration at an unspecified point during development.

The iPhone 18 Pro and iPhone 18 Pro Max launched in September 2026 with 12GB of RAM, a figure confirmed through Xcode 27 data and matching the iPhone 17 Pro models.

The iPhone Duo, Apple's first foldable handset, is also expected to ship with 12GB, though Xcode had not yet included the device when the Pro models were verified.

iPhone 18 Pro RAM Cut Tied to Global Memory Shortage

The shift away from 16GB appears to be a direct response to the global DRAM shortage that has affected the tech supply chain throughout 2026. In March, a report from The Bell indicated Samsung would supply 12GB memory modules for the iPhone Duo, while also noting sharply rising prices for those components.

Bloomberg's Mark Gurman subsequently reported that memory costs led Apple to discuss a higher starting price for the foldable device.

Supply chain analyst Ming-Chi Kuo had predicted in April 2025 that the iPhone 18 lineup would feature 12GB of RAM, a forecast that proved accurate despite the apparent earlier ambition for 16GB.

Analyst Jeff Pu made a similar projection in January 2026 for both the Pro models and the foldable iPhone. Kuo later said in August 2026 that DRAM shortages were forcing Apple to scale back its 2026 hardware shipment plans.

It is worth noting that Instant Digital's post does not specify when Apple considered the 16GB configuration.

An early engineering target is a different thing from a late cut, and the leak does not distinguish between them. Apple has not commented on unshipped configurations, so this is likely to stay unverified.

iPhone Duo Pre-Orders Begin 16 October as 12GB RAM Confirmed

The iPhone Duo pre-orders begin on 16 October, ahead of general availability on 23 October, according to Apple's official announcement. The device is expected to feature the same 12GB RAM as the iPhone 18 Pro models, positioning it in the Pro tier for iOS 27's Apple Intelligence features, which require a minimum of 12GB of unified memory.

For buyers, the practical takeaway is straightforward. Two generations of Pro iPhones now sit on the same 12GB, which is the part that matters for day-to-day performance and future software support.

Nothing was removed from a shipped product. It is a bump that reportedly was planned and did not ship, a distinction that matters more to spec enthusiasts than to most punters.

Nothing is confirmed yet about the exact timeline of Apple's 16GB consideration, so everything should be treated as unverified. IBTimes UK cannot independently verify these claims.

What is on the record remains clear. The iPhone 18 Pro and iPhone 18 Pro Max feature 12GB of RAM, confirmed through Xcode 27 data in a 9 September 2026 report. The iPhone Duo is also expected to have 12GB, though the Xcode data used to verify the Pro models did not yet include the foldable.
