Wireless charging on the back of the Apple 15 is enabled via a magnetic connection, requiring no additional connectors or interfaces. Not installing a wireless charger will not affect the operation and restart of the phone, but if there are metal objects in the back of the phone, it may affect the effect of wireless charging, and may cause the phone to heat and performance decline. Therefore, it is recommended to use the original manufacturer certified wireless charger to ensure the best charging effect and mobile phone safety performance.
