Apple's latest iOS 27 beta is drawing attention for clues that point beyond software and toward a new hardware direction. Code discovered in the update includes references to multiple internal batteries, a detail that would make sense for a foldable iPhone design.
According to findings from Macworld, the beta contains Battery Health strings that refer to "batteries" rather than a single battery, including language about one battery not being genuine. That wording suggests Apple may be preparing system support for a device built with separate power cells on each side of a folding display.
The same beta also appears to include references to angle detection and fold states, two terms that strengthen the case for a foldable form factor. Similar battery layouts are already used in other foldable smartphones, where compact cells are split to support the device's shape and screen demands.
Apple has not announced a foldable iPhone, and the company has not confirmed any product details. Still, the software clues indicate that iOS 27 may already be being shaped with a new category of device in mind. If that direction continues, Apple's next major iPhone evolution could blend familiar design language with a more flexible mobile experience.
The coming months may show whether these signals are early groundwork for a foldable iPhone, and how Apple could redefine premium smartphone design for the next generation.
