A leaker claims to have the specifications for both of the batteries expected in the iPhone Fold, and the suggestion is that despite its thin chassis, it will have all-day battery life.
The two sides of the iPhone Fold are each expected to house a battery.
A leak in February 2026 claimed that the iPhone Fold would have the largest-capacity battery of any iPhone ever, but stopped short of any specifics. Around the same time, a separate rumor said that capacity would be 5,000 mAh, and the battery would have two cells that are “3D stacked.”
Now leaker Digital Chat Station has posted on the Chinese social media site Weibo that the iPhone Fold will have a battery capacity of at least 4,883 mAh. This figure is said to have come from regulatory filings made by an unspecified battery supplier.
