Apple's iOS 27 Beta Reveals Dual‑Battery Code Hinting at Foldable iPhone

Apple’s iOS 27 developer beta includes system strings that reference “batteries” instead of the usual singular “battery,” suggesting software support for a device with dual battery cells. The code also mentions fold‑state handling and dual‑screen setups, reinforcing speculation that Apple is preparing its first foldable iPhone, dubbed the “iPhone Ultra.” Leaks propose a 7.8‑inch main display with a 5.5‑inch cover screen, dual batteries of 1,921 mAh and 2,962 mAh for a combined 4,883 mAh capacity, a 48‑megapixel main and ultra‑wide camera, and a launch window in September priced between US$2,000 and US$2,500. Apple has not confirmed the rumors, and no official comment has been provided.

The discovery mirrors earlier iOS 27 leaks that showed support for various folding angles and multitasking features for flexible displays, indicating that Apple may be finalising the software foundation before moving to mass production.
