1. The charging control circuit is faulty;
2, the charger is faulty;
3, poor interface contact;
4, the battery performance is close to failure. According to the phenomenon you described, there are only two reasons: 1 is the charging head is broken (whether it is the original or it brand, the charging head is used inside the resistance, capacitor step-down rectification, and then voltage regulation into 5V power supply, the advantage is small size and large current, the current can reach 1-1.5A; The disadvantage is that the performance is not good, the voltage is unstable, and if the capacitor breakdown is possible to damage the phone); 2 is that the battery has failed, has not reached the nominal voltage and capacity. You can verify that the method is to plug the phone into the computer or use the switching power charger (that is, the old big charger with USB interface) on the charge, if the power is constantly, then it is the problem of the original charger, on the contrary, if the fault is still, then the battery has failed. It is recommended that when charging the mobile phone, you should try to choose a switching power type charger, but the charging current should be controlled below 0.5A, so that the phone can avoid hot charging, but also to extend the life of the battery.
one
Cooling in the charging time we see for a while, this time we need to put the computer and charging in a cold place.
two
Replace the charging disconnect, there may be a short circuit state of the charger, it may be caused by the mismatched charger, we need to replace our original charger for charging.
three
The computer charging port is in poor contact, or the charger fails due to too long use, at this time we need to repair the operation of the computer, or replace the charger.
four
Charging for a while disconnect charging, may be the computer is too hot at that time, in order to protect the computer, automatically stop charging operation.
Is there a problem with the charger always cutting itself out?
First of all, you can check whether there is a problem with the magnetic card on your charger and the phone does not fit, then it is easy to break, second, we can first look at the phone's power is full, if it is full, it will automatically break
The above is about the charger always automatically cut off some views
If there is such an automatic break, automatic grade case for a long time, it is very harmful to the mobile phone battery, it will appear that the mobile phone battery is not used
The above is about the charger always automatically power off and what will be the impact of some explanations
The charging anomaly of the mobile phone may be a problem with the charger or the mobile phone itself. Users can first try to replace a set of charger and data cable to charge the phone. If it is still unable to charge normally, it may be due to problems with the tail plug, battery, motherboard and so on.
In this case, it is recommended that users send their mobile phones to the brand customer service for testing as soon as possible. The customer service engineer will find out the fault cause of the phone and inform the user after checking the phone again.
The warranty period of the mobile phone is 1 year, if the mobile phone is guaranteed and it is responsible for the warranty after natural failure. If it has been insured or caused by human failure, it can only pay for maintenance.
