Summary
iOS 27 developer beta 4 adds Battery Health text for “batteries” in plural, indicating Apple is preparing software support for an iPhone with two internal cells.
The new strings also describe replacing multiple batteries and even a single non-genuine cell, suggesting the pack could be serviced in parts rather than as one unit.
Current iPhones use one battery, making the wording a notable break from existing hardware and strengthening speculation that the code targets Apple’s foldable iPhone Ultra.
Rumors peg that model at 1,921mAh and 2,962mAh cells—4,883mAh combined—with a September debut expected alongside the iPhone 18 Pro lineup.
