Apple iPhone Ultra appears in iOS 27 code
According to Macworld, the fourth developer beta of iOS 27 contains references to an iPhone with two batteries. This can only refer to one device—the upcoming Apple iPhone Ultra. New battery health reports mention multiple internal batteries instead of a single one. MacRumors confirmed that these references are present in the beta version.
- “The batteries in this iPhone are working as expected.”
- “The condition of the batteries in this iPhone has deteriorated significantly. An authorized Apple Service Provider can replace the batteries to restore full performance and capacity.”
- “The condition of the batteries in this iPhone has deteriorated significantly, 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.”
The settings app on current iPhone models consistently refers to a single battery, so the plural phrasing seems odd. Currently, there is only one type of smartphone with more than one battery cell, and that is foldable devices.
Apple iPhone Ultra with 5,000 mAh battery
Macworld therefore suspects that the wording refers to the foldable Apple iPhone Ultra. Previous rumors suggest that the iPhone Ultra will use two battery cells with capacities of 1,921 mAh and 2,962 mAh, for a total of 4,883 mAh. The typical capacity would thus be around 5,000 mAh.
Foldable smartphones typically have two batteries, one in each half of the device. Apple will likely use the same design. Lines of code in iOS 27 suggest that the iPhone Ultra’s batteries might be individually replaceable, allowing a single faulty cell to be replaced separately. This option could reduce repair costs.
The Apple iPhone Ultra is expected to launch in September alongside the iPhone 18 Pro models. However, it is likely to be anything but cheap, even by Apple standards.
