1、 MagSafe magnetic suction charging technology for the first time

Since the beginning of iPhone 8 in 2017, Apple has added the wireless charging function to all iPhone models, which is similar to other mobile phone wireless charging methods. When it is placed on the wireless charger, it starts charging.

Apple is optimistic about the wireless charging function, but admits that the wireless charging depends on the alignment of the transmitting coil and the receiving coil. The traditional wireless charger can not achieve the best effect when it is placed at will. If it is placed askew, it will bring problems such as low efficiency of wireless charging, poor power, slow charging and serious heating, which hinder the development of wireless charging and bring bad experience.

Starting from the root, Apple has launched a new MagSafe magnetic charging technology to solve the bad experience of traditional wireless charging. The iPhone 12 mobile phone, peripheral accessories and charger are equipped with MagSafe magnetic parts to achieve the effect of automatic positioning and alignment. The iPhone 12, iPhone 12mini and iPhone 12pro are equipped with new MagSafe magnetic charging technology.

2、 How MagSafe magnetic charge works

As can be seen from the perspective of iPhone 12, the MagSafe magnetic suction charging system has a unique component structure, a unique winding coil to withstand greater receiving power, a nanocrystalline panel to capture magnetic flux, and an improved shielding layer to receive wireless fast charging more safely.

A dense magnet array is integrated in the periphery of 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 respond immediately to the change of induced magnetic field strength, so that it can quickly identify magnetic suction accessories and prepare for wireless charging.

3、 What is the charging power of MagSafe

Since the iPhone 8 was equipped with 7.5W wireless charging, the wireless charging power of all previous iPhones has stopped at 7.5W. MagSafe magnetic absorption charging technology has doubled the wireless charging performance, with the maximum power of 15W.

In addition to MagSafe magnetic suction charging, the full range of iPhone 12 still supports a wide range of Qi wireless charging with power up to 7 . 5W。

Users need faster charging speed, can use the original MagSafe magnetic suction charger, and the market wide circulation of Qi wireless charger can continue to use.

4、 Different usage of MagSafe magnetic suction charging

Compared with traditional chargers, MagSafe magnetic suction charger is quite different in use. In terms of appearance, MagSafe magnetic suction charger is a bit like apple watch’s magnetic suction charger. The metal shell is flat and round, with a power supply cable, which is small and light.

When the iPhone 12 is placed, the MagSafe magnetic absorption charger will bounce up directly because of its strong magnetic force and emit a “tower” sound. It will automatically align with the magnetic ring on the mobile phone and firmly absorb it. The transmitting coil and receiving coil can achieve millimeter level alignment accuracy that cannot be achieved by manual placement, so as to achieve high efficiency and high power charging.

Because of the magnetic adsorption, after the iPhone 12 is fully charged on the MagSafe magnetic suction charger, it can’t pick up the mobile phone at will like the previous wireless charger, so it needs to manually separate and remove the MagSafe magnetic suction charger, which is the same as applewatch’s magnetic suction charger.

5、 MagSafe magnetic suction charging advantages

Compared with wired charging, wireless charging system is easy to use, but the process of transmitting energy across the air depends on the accurate alignment of transmitting coil and receiving coil. Apple applied magnetic absorption technology to wireless charging, which completely solved the eternal problem of wireless charging.

There is no possibility of skew, 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 is doubled from 7.5W to 15W, which greatly improves the wireless charging speed and reduces the waiting time of users.

MagSafe magnetic suction charging convenient adsorption can develop more playability. For accessories, MagSafe magnetic suction charging also supports Qi wireless charging standard, which means that third-party manufacturers can develop 7.5wqi standard magnetic wireless charger and other accessories by themselves. In the future, I believe Apple will adopt MFI like standard to open MagSafe magnetic suction charging license to manufacturers that meet the specifications, and the third-party manufacturers can develop MagSafe magnetic wireless charger and other accessories by themselves The market of square magnet parts will break out.
