Summary
Three leaked images in China appear to show the iPhone 18 Pro Max’s battery, with one label clearly listing a 5,391 mAh capacity.
That figure matches an earlier rumor for the physical-SIM version and suggests China will get that model, while the eSIM-only variant is still expected to carry a larger 5,567 mAh battery.
The same source says the iPhone 18 Pro will have 4,056 mAh with a physical SIM and 4,288 mAh in its eSIM-only version.
Compared with the iPhone 17 line, the leak points to only a 1% to 2% battery increase for the Pro, versus a much larger 9% to 12% gain for the Pro Max ahead of next month’s launch.
