The one-year exposure of the new iPhone may be extended for one or two months this year due to the epidemic. The most popular iPhone exposure in September should be the magnetic wireless charging coil. On September 7, it was reported that the latest exposure showed the products suspected of iPhone 12 magnetic wireless charging protective case.
Last week, according to the supply chain information and the magnetic wireless charging module, the charging head network predicted that Apple would use magnetic wireless charging. The magnetic suction wireless charging protective cover exposed this time is the official shell shape familiar to Apple, with flannelette and the words "Designed by Apple in California" and other conventional designs inside.
However, it also has a magnet coil array, which is similar to the magnetic coil of the rumored iPhone 12. The difference is that there is no wireless charging coil in the magnet array of the protective case.
According to the disclosure, this circle array is designed to solve the problem of "the magnetic force drops due to wearing the shell". Its magnetic array can match with the iPhone 12 and play the role of transmission enhancement, which is used to maintain the magnetic adsorption between the magnetic charging base and the magnetic charging base.
Smart Cover Case for iPad
36 strong magnets are added to the fuselage and protective shell respectively, which will not only increase the weight of the fuselage and accessories, but also increase the cost. If this revelation is hit, the price of Apple's official shell and third-party accessories will inevitably rise in the future, which may be similar to the Smart Cover (with magnetic suction and screen wake-up function) of the iPad that year.

Charging board scheme for large number of charging coils
Back to the technical level, magnetic wireless charging is essentially a common Qi standard wireless charging, but it has more magnetic structure. Magnetic wireless charging has already appeared on Apple Watch and some smart watches, and it can really solve the problem that wireless charging needs to be aligned.
"Adding a magnetic suction structure to a mobile phone or watch" and "placing a large number of coils on the charging board" are both aimed at reducing the need for alignment, but they are in opposite directions:
The former is a bit like the story of "the ancient king went on a visit and asked to pave cow leather on the road, but the minister proposed that the feet could be wrapped in cow leather". A magnet was added to enable the mobile phone to automatically align with the coil of the charging board. Sacrifice the portability of the mobile phone body, but greatly reduce the requirements for charging accessories;
AirPower, the Apple wireless charging board that rolled over before, put a large number of coils on the charging board (it is said that AirPower was cut down because the Apple Watch's private wireless charging protocol was too hot and the problem could not be solved).
