Whether Apple wireless charging damages the battery mainly depends on the usage of the charger and the charging and discharging cycle of the battery.
The principle of a wireless charger is electromagnetic induction, which generates a magnetic field through current, and the phone charges the phone by inducing the current through the magnetic field. Apple officially stated that as long as the correct wireless charger is used, wireless charging will not cause damage to the battery. Wireless charging and wired charging are essentially the same, both providing power to the battery, but with different charging methods.
The most important factor affecting the service life of a battery is its charging and discharging cycle, which refers to the process of the battery from no charge to full charge, and then from no charge to full charge. Whether using wireless charging or wired charging, as long as you follow the correct charging habits and avoid overcharging or overdischarging, you can effectively extend the service life of the battery.
The energy conversion rate of wireless charging is usually high, which means that there is less energy loss during the charging process and also helps to protect the battery. However, if you frequently pick up and put down your phone for wireless charging, it may have a certain impact on charging efficiency, but it will not directly damage the battery.
Apple wireless charging will not cause damage to the battery under normal use. To extend the lifespan of the battery, it is recommended that users choose a legitimate wireless charger and follow the correct charging habits. At the same time, it is also possible to consider using a mobile phone cooling device during charging to reduce the impact of the heat generated during charging on the battery.
