It's better to hurt the battery with a wire. Because magnetic charging will generate heat, and the temperature inside the battery will greatly shorten the battery life, no effect can be seen in the short term, but it will affect the battery life in the long term.
In addition, the electromagnetic wave of the magnetic charger will have an adverse effect on the battery, causing the battery to heat up, reduce capacity, and shorten life.
If you use wire charging, it is relatively safe and the battery life is relatively longer.
It is recommended to use the original charger, do not use cheap counterfeit charger, so as not to damage the battery.
Magnetic charging damage the battery.
The reason is that the MagSafe magnetic charging method is easier to heat the battery under the same use, and heating is easy to accelerate the loss of the battery. But this speed up, as long as the usual attention to use basically can be ignored. On the other hand, MagSafe does solve the problem of wireless charging alignment, which is officially advertised. Click! A sound, very image, while making the wireless charging speed increased from 7.5W to 15W.
The magnet damages the battery.

Magnetic charging is convenient; Wired charging is faster and can achieve PD fast charging, but it is relatively not so convenient.

The Apple iPhone8 began to support wireless charging, and the iPhone12 was upgraded to MagSafe magnetic charging. The advantage of MagSafe magnetic wireless charging is that the magnetic force is quickly adsorbed to make the mobile phone and wireless charging more firm, and there is no need to worry about the location of the charge when charging.
