Apple continues to work on its first foldable iPhone, expected next year alongside the iPhone 18 Pro models. A new report now reveals that one key area could become a significant advantage for the device: The battery. According to a source with ties to the supply chain, Apple is considering incorporating a battery with a capacity of over 5,000 mAh, a move that could put the foldable iPhone in a clear advantage over Samsung’s Galaxy Z Fold series.
While Samsung unveiled the Galaxy Z Fold 7 this year with upgrades based on customer feedback, it retained a disappointing 4,400 mAh battery, identical to the previous model. The Galaxy S25 Ultra also came again with a 5,000 mAh battery, and its successor is expected to offer the same level. If Apple indeed opts for a significant jump beyond 5,000 mAh, it could pressure Samsung to finally improve the batteries in its foldable devices.
However, not everything is expected to favor Apple. According to early leaks, the foldable iPhone may lag behind Samsung’s flagship models in most other areas. Estimates suggest it could struggle to compete even with the current Fold 7, let alone the Galaxy Z Fold 8, which will feature a higher-quality display, a particularly powerful chip, and a design that has improved significantly in recent years.
Apple has not yet chosen a battery supplier, so the exact capacity is not final, but it has already begun finalizing the other hardware components.
