The iPhone 12 Mini is a true small screen lightweight flagship compared to many Android players who are trying to lose weight. < p > < p > the iPhone 12pro model continues the large cup strategy, which is divided into iphone12 pro and iphone12 Pro max. it is also equipped with 5nm A14 bionic processor, super ceramic crystal panel, matte texture glass back plate, and stainless steel material with higher hardness. < / P > < p > also thanks to the vertical narrow frame design, the iPhone 12 pro and the iPhone 11 Pro have a 6.1-inch OLED full screen with a resolution of 2532 x 1170 pixels, while the iPhone 12 Pro Max has a 6.7-inch OLED full screen with 2778 x 1284 pixels. The powerful three camera imaging system is adopted in the post shooting. The f1.6 main camera with larger background, 2x (pro) / 2.5x (pro max) light zoom, and the CMOS sensor anti shake technology on professional camera are used to make the handheld long exposure up to amazing 2 seconds. With a laser radar scanner, it has become the most powerful iPhone in history. < / P > < p > since iPhone 8 in 2017, Apple has added wireless charging function to all iPhone models, which is similar to other mobile phone wireless charging methods. It starts charging when it is placed on the wireless charger. Apple is optimistic about wireless charging, but frankly speaking, wireless charging relies on the alignment of transmitting coil and receiving coil. Traditional wireless charger cannot achieve the best effect when it is placed at random. If it is put askew, it will lead to problems such as wireless charging efficiency reduction, power failure, slow charging and serious heating, which hinders the development of wireless charging and brings bad experience. < p > < p > Apple has launched a new MagSafe magnetic charging technology to solve the bad experience of traditional wireless charging. The iPhone 12 phone, peripheral accessories and charger are equipped with MagSafe magnetic components to achieve the effect of automatic positioning and alignment. The iPhone 12, iphone12 mini and iPhone 12 Pro are equipped with new MagSafe magnetic charging technology. < / P > < p > as can be seen from the perspective of the iPhone 12, the MagSafe magnetic suction charging system has a unique winding coil to withstand higher receiving power, captures the magnetic flux through the nanocrystalline panel, and adopts an improved shielding layer to receive wireless fast charging more safely. A dense magnet array is integrated around the wireless receiving coil to realize the automatic alignment and adsorption with other magnetic suction accessories, so as to improve the wireless receiving efficiency. Equipped with a high-sensitivity magnetometer, the iPhone 12 can quickly identify magnetic suction accessories, ready for wireless charging. < p > < p > since the iPhone 8 is equipped with 7.5W wireless charging, the wireless charging power of previous generations of iPhones has stopped at 7.5W. MagSafe magnetic suction charging technology has doubled the wireless charging performance, with the maximum power of 15W. < / P > < p > in addition to MagSafe magnetic charging, the full range of iphone12 still supports Qi wireless charging with a wide range of versatility, up to 7.5W. Users need faster charging speed and can use the original MagSafe magnetic charger, while Qi wireless charger, which is widely circulated in the market, can continue to use. < p > < p > compared with traditional chargers, MagSafe magnetic suction charger has a big difference in use. In terms of appearance, MagSafe magnetic suction charger is a bit like apple watch’s magnetic suction charger. Its metal shell is flat and round, with a power supply cable, which is small and light. < / P > < p > when the iPhone 12 is placed, the MagSafe magnetic suction charger directly bounces up due to its strong magnetic force, and sends out a “tower” sound. It automatically aligns with the magnetic ring on the mobile phone and firmly absorbs it. The transmitting coil and receiving coil reach the millimeter level alignment accuracy that cannot be achieved by manual placement, so as to realize high-efficiency and high-power charging. < / P > < p > because of the magnetic adsorption, after the iPhone 12 is fully charged on the MagSafe magnetic suction charger, it can’t pick up the phone and walk away as it used to be. It needs to manually separate and remove the MagSafe magnetic suction charger. This operation is the same as apple Watch’s magnetic suction charger. < / P > < p > compared with wired charging system, wireless charging system is easy to use when discharging and charging, but the process of energy transmission in space is very dependent on the precise alignment of transmitting coil and receiving coil. Apple’s application of magnetic suction technology to wireless charging has completely solved the problem of wireless charging difficult to align. There is no possibility of distortion, so that the wireless charging efficiency can be optimized, and it is feasible to improve the wireless charging power. The wireless charging power of this generation of iPhone 12 can be doubled from 7.5W to 15W, greatly improving the speed of wireless charging and reducing the waiting time of users. For accessories, MagSafe also supports Qi wireless charging standard, which means that third-party manufacturers can develop 7.5W by themselves Qi standard magnetic wireless charger and other accessories, I believe that Apple will also adopt similar MFI standards to open MagSafe magnetic suction charging license for manufacturers that meet the specifications, and the third-party magnetic suction accessories market will usher in an explosion. < / P > < p > MagSafe dual charger has a white leather appearance. Soft connection is used between the two areas. The apple watch area has a mechanical structure, which can be turned down and flat. It supports the overall folding and storage of the external belt, which is more convenient. < p > < p > Belkin, Apple’s strategic partner, has also launched MagSafe car holder, which can be easily installed in the air conditioner outlet through the rear clamp. Compared with other elastic clamps, the magnetic suction system is more convenient to use, and it can also supplement the charging power of the mobile phone while using iPhone navigation in the car. < / P > < p > home users often need to face the demand of charging multiple Apple devices at the same time. Belkin Belkin MagSafe multi charging base is just to solve this problem. It has three wireless charging areas, and supports the simultaneous charging of Apple watch, airpods and iPhone. Among them, the iPhone area can see the mobile phone tilted in the air, and MagSafe magnetic suction wireless charging design is also adopted. < / P > < p > Apple has launched a new protective shell with magnets. It can be made of silica gel, transparent and leather in various colors. It is easy to snap on the iPhone by suction and take it off easily. With the magnetic protection case, the user will not be affected by the use of other magnetic suction accessories, and the magnetic suction protective case will not be affected. It can be charged normally with MagSafe magnetic absorption charger. < / P > < p > in addition to the protective case, Apple has also introduced MagSafe magnetic card bag, which can be put into bank card, traffic card and other conventional cards. It can be easily attached to the back of the iPhone 12 or MagSafe magnetic suction case by magnetic force, so it is more convenient for users to carry cards when they go out with light load. < / P > < p > the launch of iphone12 series once again brings the strongest iPhone in history, 5g high-speed communication, professional camera system, and powerful computing power of 5nm A14. In terms of charging, wired charging supports 20W PD fast charging, while wireless charging is a big change. The newly developed MagSafe magnetic suction wireless charging system is aimed at user experience, making coil automatic alignment more convenient and easy to use, doubling the wireless charging power to 15W, and compatible with 7.5W Qi wireless charging standard. < / P > < p > wireless charging has unlimited possibilities. MagSafe magnetic suction wireless charging will change people’s use habits and improve the fragmented charging experience of iPhone, which is a change both in the market and in the industry chain.
