Summary
A new supply-chain leak says Apple’s iPhone 18 Pro Max will ship with a 5,425mAh battery in the eSIM version and 5,235mAh in the physical-SIM model.
Those figures would mark gains from the iPhone 17 Pro Max’s reported 5,088mAh eSIM battery and 4,823mAh physical-SIM pack, with the eSIM variant again carrying the larger cell.
The same wave of leaks points to broader Pro upgrades, including a vapor chamber, a smaller Dynamic Island layout and Samsung M16 LTPO+ OLED panels with 1Hz-to-120Hz refresh rates.
Camera and connectivity rumors also center on a 48MP triple-camera system, Apple’s C2 modem with 5G mmWave and satellite features, while the iPhone 18 Pro is expected to start at $1,399.
