iPhone 18 Pro Max's Larger Battery Capacity Allegedly Revealed
The upcoming iPhone 18 Pro Max will be equipped with a nearly 12% larger battery compared to the iPhone 17 Pro Max, according to an apparent leak. An alleged photo of a battery pack for a Chinese model of the iPhone 18 Pro Max with a SIM card tray lists a capacity of 5,391 mAh, up from 4,823 mAh for the equivalent iPhone 17 Pro Max battery.

An alleged leak suggests the upcoming iPhone 18 Pro Max will feature a battery capacity 12% larger than its predecessor, the iPhone 17 Pro Max. A purported image of a battery pack for a Chinese version of the iPhone 18 Pro Max surfaced on Korean platform Naver, indicating a 5,391 mAh capacity compared to 4,823 mAh for the iPhone 17 Pro Max.
The same capacity appeared in a regulatory database last month, lending credibility to the leak. For the U.S. model, which lacks a SIM card tray, the Naver post claims a 5,567 mAh battery, representing a 10% increase over its predecessor. However, the smaller iPhone 18 Pro will reportedly have a 4,288 mAh battery, a mere 1% improvement over the iPhone 17 Pro's 4,252 mAh.
Apple's decision to continue including a SIM tray in non-U.S. models allows for a slightly larger battery, while U.S. devices have been eSIM-only since the iPhone 14 lineup. The table summarizes the alleged battery capacities for each iPhone generation, highlighting the increases in capacity.
