The upcoming iPhone 18 Pro is rumored to continue the battery strategy Apple introduced with the iPhone 17 Pro, offering different battery capacities depending on the region.
According to tipster Digital Chat Station, the Chinese variant of the iPhone 18 Pro will feature a 4,056mAh battery, while the US model is said to pack a slightly larger 4,288mAh cell.

A similar approach was adopted with the iPhone 17 Pro lineup. The difference stems from the fact that Chinese models include a physical SIM card slot, whereas iPhone 17 Pro units sold in the US are eSIM only.
The extra internal space freed up by the removal of the SIM tray allowed Apple to fit a larger battery in the US variants. In China, the iPhone 17 Pro came with a 3,988mAh battery compared to US models’ 4,252mAh unit.
The iPhone 18 Pro and 18 Pro Max are expected to debut in September with the A20 Pro chipset, a variable-aperture main rear camera, smaller dynamic island, and new color options.
