Summary
Macworld found iOS 27 beta 4 code strings for a multi-battery iPhone, including battery-status and battery-health messages written in the plural.
A regulatory filing points to two cells rated at 1,921mAh and 2,962mAh, giving the device a combined 4,883mAh capacity.
The code backs an earlier leak from Weibo account Digital Chat Station that Apple’s upcoming iPhone Ultra will use two internal batteries.
That setup is common in foldables but would be a first for the iPhone, fitting earlier iOS 27 clues pointing to a foldable, multi-display Ultra model expected in early September.
