It's all right. It will not affect the use of the phone, but you can best go to change a charging cable first. Receiving\/transmitting coils are arranged at both ends of the mobile phone and the wireless charger. The current of the wireless charger generates a magnetic field through the coil at the transmitting end. When the coil at the receiving end of the mobile phone is close to the magnetic field, the current will be generated, and then it will be converted into usable DC direct current by the rectifier voltage regulator filter circuit built in the mobile phone.
