Foldable iPhone Ultra Battery Capacity Allegedly Registered by Supplier

Apple's battery supplier has registered two new battery cells believed to be destined for the company's rumored foldable iPhone, according to a prolific Chinese leaker. In a post on Weibo, the leaker known as Digital Chat Station said that the two cells have rated capacities of 1,921mAh and 2,962mAh, for a combined minimum rated capacity of 4,883mAh. "The supply chain is also predicting a total battery capacity of 4,800–5,000mAh, though this still needs further confirmation," the leaker added. If accurate, the dual-cell design would be in line with existing book-style foldable smartphones, which typically split the battery across the device's two halves. In terms of where it sits next to rival foldables already on the market, the Google Pixel 10 Pro Fold has a total battery capacity of 5,015 mAh, while the Samsung Galaxy Z Fold 7 has a 4,400 mAh capacity. For comparison's sake, the iPhone 18 Pro and iPhone 18 Pro Max are believed to come with 4,288mAh and 5,567mAh batteries,
