Digital Chat Station posted on Weibo that the iPhone Fold will house a 4,883 mAh battery, split into two cells of 1,921 mAh and 2,962 mAh. Earlier February leaks suggested a larger 5,000 mAh pack and called the cells 3D stacked. The new figure comes from regulatory filings by an unnamed battery supplier and fits a total capacity range of 4,800–5,000 mAh.

The iPhone 18 Pro was rumored to have a 4,288 mAh battery, meaning the Fold’s combined capacity would be roughly 14 % higher. Apple’s design goal for a thin, foldable device forces it to split power across two sideswm, with one side hosting the motherboard and the other a larger battery module.

If the numbers hold, consumers will see a device that offers longer daily use than the latest non‑foldable iPhone, but the split‑cell design may impact charging speed and overall power density. Apple will need to balance the Fold’s slim profile with the practical limits of dual batterieswerfen.

Concrete analysis: the 4,883 mAh capacity signals Apple’s willingness to compromise on power density to maintain a razor‑thin chassis, setting a precedent for future foldable smartphones that prioritize form over raw energy storage.
