Hello, mobile technician. Here is the complete repair solution for the Samsung Galaxy A54 5G charging issue. This problem is often caused by a defective NTC (negative temperature coefficient) resistor on the mainboard.
The Samsung A54 SM-A546 F is considered a common issue with punctuation charging, often due to physical damage or water damage to the charging connector pin. However, other causes of this problem may include a defective charger or phone battery problem.
Be sure to check that the charging port has no dirt, lint, debris, or foreign items that can block the charging cable. The presence of dirt or debris in the port can usually fail charging. If you suspect that the port is dirty and to stop charging, clean it using compressed air can. Avoid putting anything in the port to prevent damage to the system.
What is NTC in a Samsung phone?
NTC means negative temperature coefficient thermister.
It is a small inhibitor that monitors and controls battery temperature during charging. If the NTC is damaged, the phone may display “battery temperature too much/low” warning and stop charging.
Common symptoms of NTC failure and Charging Paused Problem
- Battery temperature error when charging.
- The phone is not charging even with a good charger and cable.
- Sudden charging stop or overheating alert.
- The device is restarted during charging.
Samsung Galaxy A54 Charging Paused Problem Solution:
In the Samsung A54 5G (A546), four NTC resistors are located on the mainboard. If any of these resistors is damaged or missing, you will have to face battery charging temperature errors.
👉 To fix the problem:
- Identify the defective NTC on the motherboard (see image diagram).
- Remove the damaged part.
- Change it with a working NTC stop.
- Gather the phone again and test the charge again.
Check the charging port:
See for any external damage, dust or moisture. If necessary, clean the port with compressed air or soft-bristle brush.
Change charging pin:
Charging problems can also be caused by malfunctioning or improperly charged equipment. Test if the problem persists by trying another adapter and cable.
Check the battery:
Under unusual circumstances, the battery itself can cause charge issues. If you are able to do so, try to change the battery and see if it solves the problem.
Repair Charging IC:
The IC unit may be damaged on the motherboard. You can be diagnosed with damaged integrated circuits and are potentially repaired by a qualified technician.
Reset the phone:
Resetting the phone will help clean any software problems that can prevent the phone from being charged. Before resetting the phone, make a backup copy of your files.
Changing the NTC resistance at Samsung A54 5G (A546) can solve the battery temperature error during charging. However, this repair requires professional equipment and skills. If you are not experienced in mobile repair, it is best to seek help from an expert technician.
