Recently, a tech blogger released a teardown comparison video of the iPhone Duo, revealing internal structural differences between the Chinese and US versions, which sparked concerns among netizens about potential hardware downgrades in Apple's Chinese models. On November 2, Apple technical personnel responded that Apple has not issued a specific internal statement, but all products undergo factory testing before leaving the factory, and there is no situation where the Chinese version uses lower-quality materials or hardware than other versions. The technical personnel explained that many functions of overseas models require approval from domestic regulatory authorities before they can be launched and used; without approval, the relevant functions cannot be enabled, which is the core reason for the differences in hardware configurations between versions. Apple Intelligence AI functions likewise require domestic approval before they can be made available to domestic users.
