Wireless charger does not charge what is going on when using wireless charger to charge mobile phones, sometimes meet chargingThere are many possible reasons for this failure, we can check one by one: whether the mobile phone model supports wireless charging or whether the wireless charger matches the wireless charger sometimes does not respond, first of all, it depends on the mobile phone model does not support, do not need to install wireless charging coil.
In summary, the hot wireless charging mobile phone is a normal phenomenon, mainly by the working principle of wireless charging, energy conversion efficiency, mobile phone heat dissipation design and use environmentA combination of factors. When using wireless charging, it is recommended to pay attention to the heat dissipation of the phone and avoid charging in a high temperature or an airtight environment to ensure the safety and performance of the phone.
Wireless charger mobile phone charging heat is a normal phenomenon, but if charged to hot, we should pay attention to whether there is a problem with product quality.

Wireless charging technology uses the principle of magnetic coupling to transfer power between the transmitter and the receiver. In this process, part of the electrical energy will be converted into heat, causing the phone and charger to heat up. This is a common phenomenon of wireless charging and does not mean there is a danger.
May be due to wireless chargingPower time mobile phone opened high power consumption applications, such as: King of Glory, Tencent video and so on. When the app is opened, the CPU efficiency of the phone increases, increasing the power consumption, which causes the phone to heat up. The solution at this time is: turn off similar applications when wireless charging.

Low efficiency: energy storage and transmission efficiency is less than real contact. Slow charging speed: Due to low efficiency, the charging speed is slow at the same input power. High cost: The charger needs to have an electronic circuit to push the wireless coil, and the electrical device needs to have an electronic device to change the power, both are also neededThere are wireless coils, so the cost is higher than direct contact.
Disadvantages of mobile phone wireless charging Although the technical content of the equipment is high, the economic cost of the equipment is high and the maintenance cost is large. Because of the realization of long-distance high-power wireless magnetoelectric conversion, the energy consumption of the equipment is high. As the distance and power of wireless charging devices increase, the loss of idle work will be greater.
The harm is relatively small can be ignored, although wireless charging technology has appeared in the 19th century, but the popularity of mobile phone applications is not high. It uses the principle of "magnetic resonance" to let the wireless charger pass through the air to the phone batteryCast charge. Many wireless chargers on the market do not indicate radiation values, and electromagnetic radiation standards for wireless chargers have not yet been introduced.
