The main reason for this is that the Bluetooth battery has been damaged. There are two possible solutions:
First, get the after-sales network of the Bluetooth brand to help check whether it is maintenance or battery replacement.
Second, get a special place to sell Bluetooth, they are connected with the maintenance of Bluetooth, maintenance costs are cheaper than brand after-sales outlets, but the quality of repair is not good brand after-sales. When using a Bluetooth headset, you can use Bluetooth correctly according to the use of its manual, and improper use will cause Bluetooth damage in advance. When the battery product is not in use, it should be charged frequently to keep the battery power to avoid damage.
