Since the iPhone 8 Series, Apple has introduced wireless charging for the iPhone, which is compatible with Qi wireless standard products on the market. At that time, the WPC Alliance (the maker of the Qi protocol) did not allow magnets to be added to products that support the Qi protocol, but Apple actually violated the WPC’s regulations. It is stipulated that after dismantling, we determined that there are magnets, NFC modules and Hall sensors in MagSafe, which means that Apple did not design according to the Qi certification standard, but launched another set of wireless charging design standards.

MagSafe’s 15W and Qi are completely incompatible. It can be said that they are two sets of mechanisms. The two are different in terms of operating frequency, data encoding format or data command.
