iPhone 18 Pro Max battery seen reaching up to 5,425 mAh

Battery capacity figures for Apple\'s next flagship iPhone 18 Pro Max have been floated at 5,425 mAh for an eSIM model and 5,235 mAh for a physical SIM model. The numbers, compiled from social media-based leaks, are not confirmed specifications. Compared with the iPhone 17 Pro Max, both variants would increase. Questions remain over reliability because the original source is unclear, though a recent data leak incident at supplier Tata Electronics is cited as a factor.
