The first: is the most common case, Bluetooth headset self-protection measures. Bluetooth headset if not used for a long time, then when we charge it again, it can not be charged at first, because the Bluetooth headset has not been used for a long time, the battery will be in a dormant state, at this time we need to charge the headset for 20 or 30 minutes to activate the battery, at this time the charging will not show the light, but in fact there is a rush, Wait half an hour and check again.
The second case: the contact of the Bluetooth headset or the thimble of the charging pod is broken - or the contact is poor
Because the Bluetooth contact and charging pod thimble are often used, easy to damage or black, it is easy to have poor contact, this time can only be taken to repair - if there is the same Bluetooth headset, you can cross test whether the headset contact is broken or the charging pod thimble is broken.
Third scenario: the charging bay is broken. There is no electricity inside can not save electricity, this situation is relatively rare, generally look at the charging cabin electricity indicator light can know.
Fourth situation: the power control chip of the Bluetooth headset is broken. At this time, the Bluetooth headset is not available, and it cannot be charged.
1, the charger is broken or the socket is in poor contact. It may be that the use of the charger for a long time makes the charger socket loose and the poor contact results in the inability to charge the Bluetooth headset normally. I suggest you try a new charger.
2, Bluetooth headset charging port loose contact caused by poor. Check the charging port of the Bluetooth headset, whether there is loose, poor contact, resulting in normal charging.
3, the Bluetooth headset battery is damaged, resulting in no charge. If the charger is good and the interface is not loose, it is necessary to consider that the battery is damaged. May be long-term use, resulting in battery aging, resulting in battery damage can not be charged normally, use.
