A new leak suggests the iPhone 18 Pro Max will pack the largest battery ever used in a non-folding iPhone. According to the rumor, the eSIM-only model will feature a 5,425mAh battery, while the version with a physical SIM slot will have a 5,235mAh cell.
If accurate, both variants would offer a significant increase over the iPhone 17 Pro Max and even surpass the 5,000mAh battery found in the Samsung Galaxy S26 Ultra. The upgrade could make the iPhone 18 Pro Max Apple’s most enduring flagship smartphone yet.
