On the new flagship Mi 10, there is a 30W wireless flash charge function, which increases the power of the minute, and there is a 10W fast wireless backcharge, which means that the Mi 10 can be charged for other mobile phones that need to be charged.
wireless charging adjustment frequency of the mobile phone, and the current working frequency of wireless charging is less than 1M wireless charging adjustment frequency , so it will not affect the signal of the mobile phone.
2, the current wireless charging alliance (WPC) formulated the Qi standard of the charging frequency is generally about 100kHz, it is recommended to take a look at this standard, it is the current wireless charging more mainstream standard.
3, under normal circumstances will not harm the phone, wireless charging nowThe working frequency is below 1M, so the signal of the mobile phone will not be affected. 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.
4, wireless charger operating frequency, according to QI standard is 110-205kHz Wireless charge adjustment frequency ; The frequency of mobile phone communication is in the range of 0.8GHz to 2GHz (different communication systems will vary, 1GHz=10^9Hz).. The different frequencies make the mechanism of their impact on the human body is different.
2, low frequency electromagnetic field (that is, like you said wireless charger, hair dryer type) will not have the kind of heating effect of radio frequency electromagnetic field, the possible threat to human health is mainly: low frequency electric field and low frequency magnetic field will produce or induce current in the human body, if the current is large enough, can stimulate nerves and muscles.

5, wireless chargingElectricity is a form of charging that does not require the use of a traditional wired charger to connect to a device. Based on the principle of electromagnetic induction, wireless charging is realized by generating electromagnetic fields in the charging device and then transmitting the electric energy to the device supporting the wireless charging function. The development of wireless charging technology makes it more convenient to charge the device. There is no need to worry about plugging and removing the charging cable, and the device can be placed on the charging device with the wireless charging function.
6, wireless chargers, they are essentially radio transmitting equipment, at work will send radio waves around. And in most countries, due to the needs of communication and other fields, wirelessThe electrical frequency bands have corresponding controls, so the Mi 12 wireless charging configuration conditions in production support a maximum of 50W. The "Provisional Provisions" regulations stipulate that the use of wireless charging should be regulated to avoid interference with radio services and maintain the order of air waves.
Basically no damage: Wireless charging technology uses the principle of electromagnetic induction to transmit electrical energy through magnetic and electromagnetic fields, which has no direct damage to the internal structure of the mobile phone battery. Modern mobile phones have built-in wireless receivers with voltage and current ratings, soUnder normal use, wireless chargers are safe for mobile phone batteries.
