Hidden code within the latest iOS 27 developer preview indicates that Apple is preparing for a foldable iPhone by integrating support for dual-cell battery systems. According to MacWorld, code strings in the fourth developer beta explicitly reference multiple internal batteries, a departure from the single-cell architecture used in all previous iPhone models.
Hardware Architecture Behind the Foldable iPhone
The proposed configuration includes a 1,921mAh cell paired with a larger 2,962mAh battery.
Software Foundations for a Folding Display
The transition to dual-battery management is not the only hint of a foldable form factor found in recent software updates. Earlier versions of the iOS 27 beta included code related to a “foldState,” which suggests the operating system is being optimized to detect a fold state. Furthermore, developers have identified support for widgets capable of expanding into full-page views, likely designed to leverage the increased screen real estate of a foldable display.
Did you know? While Apple has yet to confirm the existence of a foldable smartphone, industry expectations point to an unveiling alongside the iPhone 18 Pro and iPhone 18 Pro Max, likely arriving in September.
Market Positioning and Future Releases
Analysts anticipate the foldable device may be branded as the “iPhone Ultra.” Given the complexity of the hardware, including the dual-battery implementation and the folding display technology, the price point is expected to exceed $2,000. While the high-end foldable is slated for a potential release in the coming years, more accessible models like the iPhone 18 and 18e are not expected to reach the market until 2027.
