Apple's first foldable smartphone has reportedly been spotted in the iOS 27 beta code, according to a report. Expected to be called iPhone Ultra, the foldable is said to pack a multi-battery setup. The report highlights that the code strings say, “The batteries in this iPhone are performing as expected,” and “the health of the batteries in this iPhone has significantly degraded.” The latter appears to be a warning that might appear when the iPhone Ultra’s battery health falls below 80 percent. Similarly, the code strings also reportedly mention specific situations, including one where one of the batteries of the foldable iPhone model might not be a genuine Apple part.
