MagSafe’s future is not just about magnetic charging. Apple has played a retro style on the iPhone 12, and the founder’s shape reminds many people of the iPhone 4 released ten years ago. Of course, this is not a simple salute. The more compact design controls the fuselage thickness to an amazing 7.4mm, and the new super ceramic crystal panel prevents it from repeating the fragile failure of the iPhone 4 glass panel. Concept is old, design and technology are new. < / P > < p > another technology inherited from the old product is MagSafe system. Its earliest form is the magnetic suction charging port on MacBook. Later, it was replaced by the more popular usb-c due to its lightweight and unified interface. The return of MagSafe not only brings the iPhone 12 a “one-step” wireless charging experience, but more importantly, the magnetic suction function can extend the rich accessory ecology. The concept of MagSafe is derived from the design of magnetic power interface in Japanese electrical appliances, which is to avoid the safety problems caused by the power cord being pulled apart. In fact, the use of notebook computers also has this hidden danger. Of course, the greater significance is that the magnetic suction charging port does not need to be aligned to automatically adsorb, which improves the use efficiency. < p > < p > in 2006, Apple introduced MagSafe design into the first generation of MacBook Pro. The five metal pins inside the interface are palindromic design, so it can be absorbed from both sides without intentional alignment. There are indicator lights on both sides of the plug, green means full, red is charging. The design later became an iconic feature on MacBook. < p > < p > in 2015, the redesigned MacBook (retina display) abandoned MagSafe for the first time, and was gradually replaced by usb-c. There was a lot of controversy at the time, with some saying that Apple abandoned a good design. Of course, looking back now, usb-c is obviously more in line with the future trend than MagSafe in terms of charging efficiency, transmission speed and popularity, while the magnetic suction interface is slightly weaker. It’s a matter of choice. < / P > < p > Apple restarted MagSafe on the iPhone 12. On the one hand, it fills the hole left by airpower to achieve “one-step wireless charging”; on the other hand, it aims to make the iPhone completely free from cables for a broader future. < / P > < p > let’s talk about what it looks like at this stage. First of all, MagSafe on the mobile phone is not just a magnetic interface, it represents a whole set of design concepts. The iPhone 12 has an integrated charging coil and magnet array, which can be correctly positioned on the wireless charger to achieve efficient charging. MagSafe magnet accessories also contain corresponding magnets, which can be easily absorbed and “superimposed” for use. < / P > < p > the accessories currently on display include two wireless charging stands, the MagSafe charger that charges the iPhone individually, and the MagSafe duo that charges both the iPhone and the apple watch (not available yet). And a range of MagSafe cases, including a holster that can be attached to the case. < / P > < p > Apple says more third-party accessories will be added to the MagSafe ecosystem in the future. Belkin has shown off a three in one charging dock (iPhone, apple watch, airpods) and an in car magnetic suction charger. Have you found out? MagSafe’s car charger doesn’t need to install metal plates on the phone, which is one of the advantages of the built-in magnet. Recently released Dajiang mobile phone PTZ 4 has added magnetic suction quick disassembly design, which no longer needs complicated installation and leveling work. In fact, the concept is similar to MagSafe in a sense. But its implementation is to install a metal ring bracket (or metal clip) on the mobile phone. If the iPhone has magnets, wouldn’t it be much more convenient? < / P > < p > the iPhone 12 has a single turn coil NFC and magnetic sensor inside, which can identify accessories and react, which makes it more imaginative. The official video has shown the identification holster, which shows the time in a fixed position. < / P > < p > remember the Nokia N79 and nut phones that can recognize the theme color change of the back cover? It’s not convenient to change the back cover of the mobile phone. It’s not convenient to replace it with a magnetic case. Now it’s time for apple to lift its restrictions on iPhone desktop beautification. < / P > < p > the MagSafe magnetic suction accessories that can be used in combination make the iPhone possible to be “modular” in a sense. To install zoom lens and pull ring bracket, these accessories need to be attached to the back of the phone or through the phone shell. Now it can be pasted. If Apple releases the restrictions, the corresponding operation will be triggered when the accessories are replaced, such as through the Apple App clip… It’s a bit far away, but I don’t think it’s impossible. < / P > < p > in addition to the ecological possibility of accessories, Apple’s bigger “ambition” may be to completely wireless the iPhone. In the name of “environmental protection”, Apple has not included a charging head and headset in the iPhone box. After the 3.5mm interface, the next step may be to remove the charging port. The future direction is non porous and wireless. < / P > < p > all future visions are based on how Apple will open up MagSafe ecology. Basically, Apple’s control of MagSafe will be very strong. If the future vision is wireless, it means that Apple has lost a sum of MFI accessory income, which will be compensated by the new MagSafe certification. Don’t forget, iPhone 12 has the function of identifying accessories. At present, only certified charging base can achieve 15W fast charging (7.5W for the third party), so it is not difficult to control. < p > < p > the MagSafe system of iPhone 12 is a small surprise of this conference, but from the perspective of the future, it has unlimited possibilities, and it is not just magnetic charging.
