It will, but not very much. The biggest damage to the battery is using it while charging.
The whole process of mobile phone battery charging includes three stages: rapid charging, continuous charging and trickle charging. After the first two stages, although the system power display 100%, but in fact the battery has not really reached saturation state. The remaining capacity can only be replenished by a tiny pulse of current. Trickle charge is a small current charge after the battery is full, which can keep the electrons flowing and extend the service life of the electrons.
Does the Apple 12 magnetic charging hurt the battery?
No, Apple's wireless charging is also Apple's own original, will not damage the battery, but its power is not the same, charging will not lead to a rise in temperature, so it will not affect the battery. Apple's magnetic charging is also supported by Apple itself, and charging and fast charging will not affect the battery.
No, if he's capable of it, he must have experimented
