What’s going on with the iPhone12 MagSafe magnetic wireless charging

Since the iPhone 8 in 2017, Apple has added the wireless charging function to all iPhone models, which is similar to the wireless charging method of other mobile phones, and it starts charging when it is placed on the wireless charger. Apple is optimistic about the wireless charging function, but frankly said that wireless charging relies on the alignment of the transmitter coil and the receiver coil. Traditional wireless chargers cannot achieve the best results when placed at hand. If they are placed incorrectly, the efficiency of wireless charging will be reduced and the power will not increase. , Slow charging, severe heating, etc., hinder the development of wireless charging and bring poor experience.

Starting from the root cause, Apple introduced the new MagSafe magnetic charging technology to solve the bad experience of traditional wireless charging. The iPhone 12 mobile phone, peripheral accessories, and charger are all equipped with MagSafe magnetic components to achieve the effect of automatic positioning and alignment. iPhone 12, Both iPhone12 mini and iPhone12 Pro are equipped with the new MagSafe magnetic charging technology.

As can be seen from the perspective of iPhone12, MagSafe magnetic charging system component structure, unique winding coil to withstand greater receiving power, capturing magnetic flux through the nanocrystalline panel, and adopting an improved shielding layer to more safely receive wireless fast Recharge. A dense array of magnets is integrated on the periphery of the wireless receiving coil to realize automatic alignment and adsorption with other magnetic accessories, thereby improving wireless receiving efficiency. Equipped with a high-sensitivity magnetometer, it responds immediately to changes in the induced magnetic field strength, allowing iPhone12 to quickly identify magnetic accessories and prepare for wireless charging.

Since the iPhone 8 is equipped with 7.5W wireless charging, the wireless charging power of previous iPhones has stopped at 7.5W. MagSafe magnetic charging technology doubles the wireless charging performance, with a maximum power of 15W.

In addition to MagSafe magnetic charging, the entire iPhone12 series still supports Qi wireless charging with a wide range of versatility, with a power of up to 7.5W. Users who need a faster charging speed can use the original MagSafe magnetic charger, and the Qi wireless chargers that are widely circulated on the market can continue to be used.
