Multiple outlets report a new battery-capacity leak for Apple’s rumored “iPhone Ultra,” a foldable iPhone expected to be announced in September. The reports cite information attributed to a Weibo account known as Digital Chat Station, saying one of Apple’s battery suppliers has had two batteries certified as a pair specifically for a foldable device. Because foldables typically use split batteries due to their form factor, the leak presents separate rated capacities for each cell. The cited values are 1,921 mAh and 2,962 mAh, which sum to a rated total of 4,883 mAh. The reports note that “rated” capacity is usually lower than the advertised or typical capacity, and they project that the consumer-facing figure could be around 5,000 mAh. Separate coverage included in the search results also discusses expectations that the foldable battery may be smaller than some prior speculation, and mentions alternative ideas about battery configurations and runtime trade-offs. Overall, the sources converge on the supplier-certification claim and the same two capacity figures, but they continue to frame the information as unconfirmed pre-release rumor.
