The long-awaited foldable iPhone Fold is expected to launch later this year, offering a form factor unlike any existing Android foldable. According to fresh rumors from Chinese sources, the device will feature the largest battery ever seen in an Apple smartphone. While earlier estimates placed the battery capacity between 5,400mAh and 5,800mAh, the latest reports suggest it could reach up to 5,500mAh. That's nearly 10% larger than the current biggest battery in an Apple device — the eSIM-only iPhone 17 Pro Max. Combined with iOS's historically better power efficiency compared to Android, the iPhone Fold's battery life is expected to far outlast the competition. For other specs, the phone is reported to use an A20 Pro chipset and 12GB RAM, with a 7.8-inch inner display and 5.5-inch outer display. On the camera side, it's said to include two 48MP rear cameras and two 18MP selfie cameras. Ref: gsmarena
