Apple plans to equip its foldable iPhone with battery capacity ranging between 5,400 and 5,800 milliamp hours during testing phases, according to tipster yeux1122, who accurately predicted iPhone Air specifications. The power cell exceeds the 5,088 milliamp-hour unit found in the iPhone 17 Pro Max eSIM variant and surpasses competing devices, including the Galaxy S25 Ultra and Galaxy Z Fold 7.
Increased battery size will result in additional thickness and weight compared to current models, though Apple appears willing to accept these tradeoffs across its upcoming lineup. The company could utilize extra internal volume to install larger vapor chambers for enhanced thermal management alongside extended runtime capabilities.
Earlier prototypes featured a 7.74-inch primary screen and a 5.49-inch external display, though final dimensions may change before mass production begins. The device reportedly resembles two iPhone Air units positioned side by side when fully opened, employing similar miniaturized logic board technology to accommodate larger components.
