Wireless charger under normal circumstances will not harm the mobile phone, wireless charging now the working frequency is done below 1M, so the signal of the mobile phone will not have an impact. Wireless charging has no effect on mobile phone battery life, and wired charging is basically the same, but the rate is lower, but the wireless charger conversion rate is still high, more energy saving.

Wireless charger, mainly using inductive coupling technology, because the coupling technology is mainly through the magnetic field of the coil to generate current, the internal component of the battery itself can not constitute a magnetic field, so it will not damage the internal structure of the battery during the power-on process. At present, most mobile phones on the market are in line with the QI wireless charging standard, with a built-in wireless receiver, which has a rated voltage and current, so the wireless charger has no effect on the mobile phone.
Wireless charging does not directly harm the mobile phone battery, because it uses the principle of electromagnetic induction, which transmits electrical energy through the electromagnetic field to the mobile phone battery for charging. Compared with the traditional wired charging method, wireless charging will generate some heat energy, but it will have little impact on the life of the phone battery. At the same time, wireless charging can also avoid the wear and loosening of the charging cable on the interface, so as to better protect the mobile phone battery. However, it should be noted that the use of low-quality wireless chargers may generate large heat and affect battery life, so it is recommended to use a regular brand of wireless chargers.
