Multiple outlets report new leak information about Apple’s rumored foldable “iPhone Ultra,” expected to be unveiled in September. GSMArena attributes the details to a tipster known as Digital Chat Station on Weibo, saying a battery supplier has had a pair of batteries certified together for a foldable device. Because foldables typically use split batteries, the certification is presented as evidence of a total pack capacity.

GSMArena reports the two batteries have rated capacities of 1,921 mAh and 2,962 mAh, which add up to 4,883 mAh rated. The article notes that rated capacity is usually lower than the typical advertised figure, estimating the marketed capacity could be around 5,000 mAh. Other aggregated reports similarly describe supplier-related battery certification as the basis for the latest figures, while mentioning broader speculation that the device could use a dual-battery setup consistent with its foldable design.

The reports are based on unofficial claims and certification references, and they do not include confirmation from Apple.
