MFI is believed to be very familiar to Apple users. It belongs to Apple’s standard for charging accessories of its own products. Only products that meet the standard can be used normally. Otherwise, it will be unable to use after upgrading the system or using it for a period of time. At present, MFI certification is only limited to Apple’s lightning data line. However, recently, the charging head network has learned that MFI will have a big move with the advent of magnetic induction wireless charging. However, all this will start from the autumn launch in 2017. < / P > < p > let’s start with airpower and introduce Apple’s wireless charging and MFI licensing story in recent years. From birth to miscarriage, to today, you will understand. < / P > < p > in September 2017, apple held a new product launch in autumn as scheduled. In front of it, the iPhone 8 and iPhone 8p were launched in accordance with the usual rhythm. The metal material of the back plate was replaced by glass, and the back plate was used for wireless charging. There was also a “one more thing” to launch the iPhone x, which symbolizes the 10th anniversary of the iPhone, and cancelled Apple’s iconic home key for the first time. However, in the PPT demonstration of the press conference, we also saw airpower, Apple’s three in one wireless charging board. The oval white panel is placed on the table and connected with only one wire. You can easily charge the iPhone, airpods and apple watch on it. < / P > < p > however, we did not see the release of airpower in the following time. Subsequently, in the email of Apple’s engineers, we also learned that airpower would not be launched for the time being, because the heating of wireless charging board did not meet the standard of apple, and airpower was stillborn. < / P > < p > all iPhones released by Apple support wireless charging, but they have not launched wireless charging boards. In Apple’s Mall, we can see wireless charging boards launched by third-party brands such as mophie and Belkin. In addition, iPhone and airpods support the general Qi wireless charging protocol, so other wireless charging boards on the market gush out to realize wireless charging for iPhone and airpods. < / P > < p > the principle of wireless charging is actually very simple. There is a wireless charging coil in the backplane of the mobile phone, and there is also a wireless charging coil in the wireless charger. When the two coils overlap, a magnetic field will be generated to realize wireless charging. But at present, all the wireless chargers on the market are designed with single coil or double coil. That is to say, it is not necessarily possible to realize wireless charging by placing the mobile phone on the charging board at will, but also need to aim at the coil of the charging board. < / P > < p > in the twinkling of an eye, it’s not only when Apple’s airpower comes back to life on the Internet (tuyuan AIO Technology), but Apple uses a11 bionic chip to join airpower to control heat. Then, on the eve of the autumn conference, it is revealed that the “airpower” engineering machine is on the Internet, which is different from other wireless charging boards on the market This engineering machine has built-in 22 coils, which are densely stacked in the wireless charging board. You can imagine how much heat will be generated if it works. < / P > < p > this engineering machine can be said to be the closest product to airpower. Just when everyone thought that Apple would launch this late new product at the autumn conference, at 1:00 a.m. on September 16, I stayed up late to watch the apple conference, only to see the updates of Apple watch and iPad, not even the new iPhone. The spray of a stone instantly restored calm. < / P > < p > Apple’s vision is that users can place their mobile phones on the wireless charging board at will to realize charging without having to find the correct location, but they are forced to give up because the heating does not meet the standard. It should be mentioned here that the apple watch uses magnetic charging, so Apple plans to transfer the apple watch charging mode to the iPhone. < / P > < p > previously, the charging head network has disclosed that the new iPhone 12 will adopt magnetic suction wireless charging, so as to realize the scenario that users can place wireless charging at will. In addition, Apple has also brought MFI certification to magnetic suction charging when using magnetic charging. < p > < p > MFI can be seen as a standard that Apple launched to consolidate its product ecology. As we all know, compared with the open Android system, Apple’s system is closed. Android is highly playable, and can change themes, desktop, etc., but only the default theme interface can be used on the IOS side (except for prison break). The two systems follow two completely different paths. Let alone Android for the time being, the closed feature of IOS system is bound to be very easy to manage. Whether it’s an app launched on the shelf or the charging accessories to be said today, it needs to be To pass Apple’s certification can be put on the shelf and stable charging use, such a feature is also doomed to be not suitable for users who love to toss around. < / P > < p > only MFI certified accessory products can be used safely and stably with Apple products. MFI certified accessories will be printed with made for IOS on the package to prove that the products have been certified. However, some manufacturers have not been certified but have printed the logo on the packaging. At this time, you can go to Apple’s official website for inquiry. MFI is a certification standard, which is mainly reflected on the MFI chip. In the charging accessories, only the chip integrated with MFI can connect and communicate with Apple products such as iPhone and iPad, and it is not a simple thing to pass MFI certification. < / P > < p > first of all, if you want to obtain MFI chip, you must pass MFI certification. Enterprises need to submit materials to apple. Then Apple will review the qualifications of the enterprise. If the audit is passed, it will become a member of MFI and have the qualification to buy MFI chips. But getting MFI membership does not mean that you can always hold it. If the operation steps do not meet Apple’s requirements, it may be disqualified at any time. < / P > < p > has become a member of MFI and can buy MFI chips. However, this does not mean that you can buy MFI chips in batches and produce accessories immediately. When MFI chips are available, trial production can be carried out. The products produced need to be sent to apple for testing. After the approval, the batch production and sales can be carried out. It takes about 3 months to 6 months from the application for MFI certification to the mass production, so the process is still It’s a long time. < / P > < p > in the end, from the production factory to the consumer’s hand, we will finally see the charging product with MFI certification and built-in MFI chip. As for why such a certification standard will be introduced, whether the product can be stably connected to communication or charged a patent fee in the name of so-called “security”. Maybe the two coexist. When the charging cable is connected to the mobile phone, the other end of the charging cable is not only connected with the charging head, that is to say, an apple charging line does not only have the function of charging, but also plays the role of transmitting data and even audio and video signals. Therefore, apple is also considering the sound use of its own products. < / P > < p > so it’s not easy to finally pass Apple’s MFI certification and buy MFI chips in bulk. Many companies will be rejected in a certain link. And getting MFI license from Apple has become a symbol of technology and quality strength. Because the passing rate of MFI certification is only 2%, it is very difficult to obtain MFI authorization. < / P > < p > at present, there are many charging accessories that have passed MFI certification on the market, but they all have one common feature, which is not cheap. The price of a MFI certified Apple fast charging line is about 50 yuan. If it is a better quality braided body, it will be more expensive. In fact, it’s not up to the wire rod manufacturers to decide. Purchasing certified raw materials from Apple may cost 2-digit prices. Naturally, the cost is very high. Therefore, the apple data line with a price of more than 10 yuan or even 9 yuan / 9 package mail on the market is definitely not certified. < / P > < p > in 2017, apple replaced the back panel of iPhone with glass material for wireless charging. After experiencing the failure of the original airpower multi coil, apple made a comeback in 2020. It used the magnetic charging mode to enable users to realize the scene of charging on demand. In addition, the MFI certification standard for charging interface was transplanted to the magnetic suction wireless charger, In the field of wireless charging, apple once again copied the scene of MFI authentication. < / P > < p > Apple has achieved innovation in many fields. The annual Apple press conference has become the “Spring Festival Gala” in the science and technology circle. Every new product released has attracted much attention. For Wireless charger, maybe Apple wants a perfect solution, or it will not do it, and it will lead the way. < / P > < p > we believe that the future is the era of wireless, wireless headphones, wireless charging board, and all products are connected wirelessly. However, the development of science and technology still needs time and process, and now it is impossible to realize all wireless status. However, we can see the efforts of the major scientific and technological enterprises for wireless. < / P > < p > in 2017, airpower was stillborn, and now in 2020, Apple will return again in the way of magnetic suction wireless charging, and it is also attached with MFI certification standard. Such a move is a big move for the industry, and it will affect the whole body. Once Apple introduces the iPhone 12 with built-in magnetic suction wireless charging coil and magnetic suction wireless charger, a new charging method will appear. < / P > < p > now, whether other wireless chargers on the market can be used and whether the market will reshuffle involves all aspects of the category. Whether Apple’s action on wireless charging will affect users’ use habits is unknown at present. According to the usual Apple autumn conference, there is no iPhone It may not be known until Apple’s iPhone 12 series is launched. Global Tech
