Apple iPhone Ultra foldable hinted by iOS 27 beta dual‑battery code

The fourth beta of iOS 27 contains internal strings referring to “the batteries of this iPhone” and to “one of the batteries”, indicating that the operating system is prepared to manage two separate battery cells. Such a configuration aligns with a hinge‑based design and points to Apple’s expected first foldable phone, dubbed the iPhone Ultra, slated for an autumn launch. The code also includes detections for folding angles and the ability to flag non‑original battery modules, signaling that the device’s software will monitor each cell independently. Apple has long kept details of a foldable iPhone secret, but these software clues provide the most concrete evidence yet of the upcoming hardware.
