Apple’s iOS 27 fourth developer beta includes code strings that appear to reference a foldable iPhone model with more than one battery, according to reports from Macworld and coverage by MacRumors and others. The new Battery Health–related wording, found in iOS 27 beta 4, uses plural language such as “the batteries in this iPhone are performing as expected” and “the health of the batteries in this iPhone has significantly degraded.” The messages are similar in purpose to current iPhone Battery Health alerts, including references to Apple Authorized Service Providers being able to replace batteries to restore full performance and capacity. The strings also reportedly include a scenario where one battery “could not be verified as a genuine Apple battery,” implying separate battery identification and validation. One reported implication is that a foldable device—widely rumored to be called the iPhone Ultra—could have batteries located in different sections of the handset, and that Apple may support replacing individual batteries rather than an entire pack. The reports state the iPhone Ultra is expected to debut in September alongside other new iPhone models.

- iOS 27 developer beta 4 includes new Battery Health code strings that use plural “batteries” language.
- The strings reference battery replacement by an Apple Authorized Service Provider to restore full performance and capacity.
- The code includes a case where one battery cannot be verified as a genuine Apple part.
- Reports link the multi-battery wording to the rumored foldable iPhone, expected to be called the iPhone Ultra.
- Current iPhone Battery Health wording in Settings typically references a single battery, making the plural references notable.
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.
3 hours agoApple has rolled out the fourth developer beta of iOS 27. According to a new report, the update includes code strings that reference the company's rumored foldable iPhone, which is widely expected to be called the iPhone Ultra. The folks over at Macworld discovered new code strings in the Battery Health section of iOS 27 Beta 4 that reference an iPhone with multiple batteries.

7 hours agoThe fourth developer beta of iOS 27 has references to an iPhone with two batteries, according to Macworld. New Battery Health strings include mentions of multiple internal batteries, instead of a single battery. MacRumors confirmed the mentions are in the beta. "The batteries in this iPhone are performing as expected." "The health of the batteries in this iPhone has significantly degraded. An Apple Authorized Service Provider can replace the batteries to restore full performance and capacity." "The health of the batteries in this iPhone has significantly degraded, and one of the batteries could not be verified as a genuine Apple battery. An Apple Authorized Service Provider can replace the batteries to restore full performance and capacity." All of the wording in the Settings app on current iPhone models references a single battery, so the plural phrasing is curious. Macworld speculates the wording references the foldable "iPhone Ultra" Apple is working on. Prior rumors suggest the iPhone Ultra will use two battery cells with 1,921mAh and 2,962mAh capacities for a total of 4,883mAh. Foldable smartphones typically have two batteries, with one located in each half of the device. Apple is likely to use the same design. The iOS 27 strings suggest the batteries in the iPhone Ultra could be serviceable separately, so a single failing cell could be swapped on its own. An option to replace a single degraded cell could lower repair costs. Apple's iPhone Ultra is expected to debut this September alongside the iPhone 18 Pro models.Related Roundups: iOS 27, iPadOS 27, iPhone FoldThis article, "iOS 27 Code References iPhone With Two Batteries" first appeared on MacRumors.comDiscuss this article in our forums
