Signs Your Charging Port May Be Faulty

1. No charging at all
You plug in the charger, but nothing happens. You have already tried a new cable and adapter with no change.

2. Intermittent charging
The phone charges only when the cable is held at a certain angle or when you press on it. This usually means the port pins are loose or worn.

3. Slow charging
Your phone still charges but takes much longer than usual. This can be caused by damaged pins or debris blocking the port.

4. Overheating while charging
If the charging area becomes hot, there could be internal resistance caused by corrosion or damage.

5. Computer not detecting phone
When you connect to a computer with a USB cable, it does not recognise the phone. The data connection inside the port may be broken.

 

Common Causes of Charging Port Damage

• Frequent plugging and unplugging of the cable over time

• Using low quality or incorrect chargers and cables

• Physical damage from drops or pulling the cable at an angle

• Dust, lint, or small debris getting stuck inside the port

• Corrosion from water or liquid exposure

• Manufacturing defects or weak solder joints

 

What You Can Try Before Repair

Before bringing the phone in, try the following:

• Test with a known reliable cable and adapter

• Check for dirt or lint inside the port using a torch

• Restart the phone to rule out software issues

• If water damage is possible, stop charging immediately and bring it in for inspection

If the above does not help, the charging port likely needs repair or replacement.

 

How YKL Repairs Charging Ports

Charging port repair is not always as simple as swapping a part. Many modern phones have the charging port soldered directly to the logic board or combined with other components like microphones or antennas.

At YKL, we begin with a full diagnostic to confirm the fault and then:

• Remove any blockages or debris safely

• Reflow or re-solder loose port connections

• Replace the charging port flex or sub board when needed

• On logic board soldered ports, carry out micro soldering replacement

• Test charging speed, data transfer, and microphone function after repair
