Apple’s long-rumored foldable smartphone, expected to arrive as the iPhone Fold, is once again in the spotlight following a new leak that reveals key details about its battery capacity.
While reports remain divided on the launch timeline—some predicting a 2026 debut and others pointing toward 2027—the latest information suggests Apple is preparing a powerful device that significantly surpasses the battery capabilities of its current flagships.
According to the leak, the iPhone Fold may pack a battery between 5,400mAh and 5,800mAh, making it substantially larger than the iPhone 17 Pro Max, which houses a 4,823mAh battery in its standard version, or a 5,088mAh unit in its eSIM-only model. If accurate, this upgrade would put the foldable iPhone among the largest battery phones Apple has ever produced.
The report indicates that Apple is currently testing prototype units equipped with the mentioned battery range. Interestingly, insiders point out that Apple has a history of revising battery sizes during development.
For instance, early prototypes of the iPhone Air reportedly featured a smaller 3,000mAh cell, but the company ultimately managed to fit a larger battery into the final production model. This suggests that the iPhone Fold could also receive further enhancements, potentially ending up with a battery closer to 6,000mAh by the time it launches.
A major reason for this larger battery is the foldable’s expected dual-display setup. Rumors claim the iPhone Fold will feature a 7.58-inch inner display paired with a 5.38-inch external cover display. Such a configuration naturally demands higher power efficiency, making a more robust battery essential to maintain long usage times without compromising the user experience.
If these leaks prove accurate, the iPhone Fold could become one of Apple’s most advanced and long-lasting smartphones to date. As anticipation grows, Apple fans and industry analysts alike will be watching closely for more concrete details on the company’s entry into the foldable phone market.
