1. There are several factors that cause heat during charging:
2. The efficiency of the mobile phone charging chip is too low, and a large amount of energy is converted into heat instead of electricity; It's a congenital disability. It's almost impossible to adjust.
3. The charging interface is in poor contact, or its own conductive impedance is too large, and the same large amount of energy is converted into heat energy rather than electric energy, which can be solved by changing a good charging interface.
4. The charging current is really large, such as 1.5a or even 2a, even if the efficiency is very high, the corresponding heat energy will be relatively high, this is a normal phenomenon, most of the high-current charging mobile phones have similar problems, in fact, the heat is not too much, but it is hotter than the usual small current charging mobile phones.
First, the heat dissipation function of Bluetooth headphones is not very good.
Second, listen to the car listening to the song for too long, the Bluetooth hand headset has been in a working state.
Third, the general Bluetooth headset is mainly used for calls, if you want to listen to music, you can buy a Bluetooth headset for listening to music, four, it is recommended that the Bluetooth headset listening to music time is not too long
