If your USB socket is charging intermittently, it may be caused by the following reasons:

1.Poor Contact

·Loose USB plug or socket: Check if the USB cable is securely connected. Try using a different socket or cable.

·Internal damage or oxidation of the interface: Prolonged use may cause the USB port to loosen or oxidize, affecting the connection.

2.USB Data Cable Issues

· Internal breakage or poor contact in the charging cable: It is recommended to replace it with a high-quality USB cable.

· Aging or damaged cable: Worn-out cables may cause intermittent charging.

3.Power Adapter or Socket Failure

· Insufficient or faulty adapter power output: This may lead to unstable power supply. Try using a different charger.

· Poor socket contact: Try plugging the charger into another socket.

4.Device Port Issues

· USB charging port of the device may be damaged or dusty, causing poor contact: Clean it using an air blower or alcohol wipes.

· Device battery or charging IC module malfunction: It is recommended to send the device for professional repair.

5.Overheat Protection

· When the charging device or adapter overheats, it may automatically reduce charging power, leading to intermittent charging.

· Avoid excessive heating during charging, especially when using the device while charging.

Solutions:

1.Try replacing the USB data cable with a new one.

2.Use a different charger or socket to check if the issue persists.

3.Clean the USB port to remove dust or debris.

4.Check for any software or hardware issues in the device (e.g., update the system or restore factory settings).

If the problem remains unresolved after trying the above methods, it may be a hardware issue, and it is recommended to send the device for repair to avoid further damage.
