iPhone Ultra May Pack 4,883 mAh Dual-Cell Battery as 2nm A20 Pro Targets Efficiency

Summary
Regulatory filings cited by leakers point to a split battery setup for Apple’s rumored foldable: a 1,921 mAh cell plus a 2,962 mAh cell, totaling 4,883 mAh.
That capacity would leave the iPhone Ultra near the low end of major foldables, trailing several rivals at 6,000 mAh or more and only narrowly topping devices like Samsung’s Z Fold 8 and Google’s Pixel 11 Pro Fold.
Battery life concerns are sharper because the device is expected to be Apple’s thinnest iPhone yet, while foldables’ larger inner displays typically consume more power than standard slab phones.
Apple’s rumored A20 Pro—reportedly built on TSMC’s 2nm process—could offset the smaller battery by cutting power draw enough to push endurance toward roughly 12.5 to 13 hours, though still short of some 14-hour-plus rivals.
