Apple’s Upcoming iPhone 18 Series, Including First Foldable Model, Expected to Run on 2nm A20 Chip

Apple is reportedly preparing to power its next-generation iPhone 18 series with its first 2nm processors, marking a major leap in mobile chip technology. According to tipsters on Weibo, the standard iPhone 18 will be equipped with the A20 chip, while the higher-end iPhone 18 Pro, Pro Max, and the company’s first foldable iPhone, tentatively called the iPhone Fold, will feature the more powerful A20 Pro chipset. This advancement is expected to bring improved energy efficiency, faster processing, and enhanced AI and graphics capabilities for Apple’s upcoming smartphones.

The A20 chipset, reportedly codenamed “Borneo,” will serve as the backbone of the standard iPhone 18, offering optimized performance for everyday tasks and better battery management. Meanwhile, the A20 Pro, or “Borneo Ultra,” is expected to power the foldable model and the Pro variants, potentially enabling smoother multitasking, advanced photography processing, and next-level augmented reality experiences.

Reports also suggest that Apple is planning a phased rollout of new form factors between 2026 and 2028, indicating that foldable devices could become a recurring part of the company’s lineup. The introduction of a horizontally folding iPhone would mark Apple’s first venture into flexible display technology, aligning it with other manufacturers that have already explored the foldable segment.

Industry analysts expect that the transition to 2nm technology could also have a significant impact on thermal management, power efficiency, and overall device performance. With the A20 and A20 Pro chips, Apple is positioning the iPhone 18 series not just as a speed upgrade, but as a platform for new features and innovations that could redefine what users expect from a smartphone.
