The answer is as follows: The Bluetooth headset will produce a certain heat phenomenon during the charging process, mainly because of the following reasons:
1. Charging current: When charging, the electric energy will be transferred to the headset battery through the charging line, and the current will produce a certain resistance during the transmission process, resulting in the conversion of electric energy into heat energy, thus heating the headset.
2. Battery charging efficiency: The battery will undergo a chemical reaction during the charging process, converting electrical energy into chemical energy for storage. However, the battery is not 100% efficient during the charging process, and some of the electrical energy will be converted into heat and lost, resulting in heating of the headset.
3. Charging protection measures: In order to protect the battery from overcharge, overdischarge and other damage, the charging circuit usually takes some protective measures, such as temperature monitoring and control during the charging process, when the temperature is too high, it will reduce the charging current or stop charging, which will also cause the earphone to heat up.
It should be noted that the headset will have a certain amount of heat during the normal charging process is normal, but if the heat is excessive or accompanied by other abnormal conditions, such as abnormal odor, charging speed is significantly slow, there may be problems with the battery or charging circuit, it is recommended to stop use in time and contact after-sales service.
It is normal for Bluetooth headphones to heat up while charging, for a variety of reasons, which can be the following:
< br >
1. The charging current is too large or overloaded. If the charger current is greater than the charging current of the Bluetooth headset, it will lead to overload and heating.
< br >
2. The charging voltage is unstable. When the charging voltage is unstable, the Bluetooth headset is not fully charged, which may also lead to fever.
< br >
3. Rechargeable battery aging. With the increase in the use of Bluetooth headphones, the degree of aging of rechargeable batteries has gradually increased, and some bad batteries may also lead to fever.
< br >
4. Overheated environment. If the Bluetooth headset is in a stuffy environment, it will also lead to heat when charging.
< br >
However, in general, the heat emitted by Bluetooth headphones when charging is acceptable and will not have significant adverse effects on the human body. If you find that the Bluetooth headset is more serious when charging, or has been hot, it is very recommended that you immediately stop using, and contact after-sales service or professionals for inspection and treatment.
< br >
It is estimated that the power management circuit of the headset turns the voltage and current in the process of conversion, because of the heat emitted by the work. It does not rule out the reason of excessive charging current. Stop charging and wait for cooling.
< br >
When charging, part of the electric energy will be converted into heat; When the current passes through the conductor, it will also generate some heat, and a slight scalding is a normal phenomenon, please rest assured. If you feel the hot situation is particularly obvious, it means that your charging current is too large, you need to change the charger, or it is estimated that the internal circuit is faulty, the charging current of the Bluetooth headset is generally not more than one hundred or two hundred mA, the current is not large, and it will not lead to fever.

Charge it. If it breaks, it doesn't work. If it works, keep using it. I can't fix this on my own.
