Apple adds full-storage overwrite erase option in iOS 27.2 beta, limited to China
iOS 27.2 beta 1 contains references to a new erase feature that overwrites an iPhone's entire storage, including unused space, with blank data rather than just destroying encryption keys. 9to5Mac found the option is currently restricted to devices sold in China, and Apple warns it takes longer and may affect device lifespan. Code references suggest the same capability is being built for iPad, HomePod, and Apple Vision Pro as well.
