GoKawiilApple 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.
GoKawiil's interpretation of the reporting above, not reported fact.
China is introducing a data-erasure standard effective January 1, 2027, requiring devices to support overwriting stored data rather than relying solely on cryptographic erasure, and this feature appears designed to meet that mandate. It highlights how regional regulation can push Apple to build hardware-level features that may later expand globally, while also raising tradeoffs between thorough data destruction and flash storage wear.
- The overwrite-erase feature is currently exclusive to Chinese iPhone models in iOS 27.2 beta 1.
- It responds to a new Chinese data-erasure regulation taking effect in 2027.
- Code hints show the feature could eventually extend to iPad, HomePod, and Vision Pro devices.
