Mobile Phone Battery Not Charging Problem and Solution

Follow these Steps One after Another:

  1. Change the charger and check. Voltage must be 5 to 7 Volts.
  2. Clean, Resold or Change the Charger Connector.
  3. If the problem is not solved then change the Battery and Check. Non Removable Battery are Just Glued at the Bottom. They can be Removed Easily but Little Carefully.
  4. Check Voltage of the Battery Connector using a Multimeter. Voltage must be 1.5 to 3.7 DC Volts.
  5. If there is no voltage in the connector then check track of the charging section. Refer to the diagram of the particular model of the mobile phone. Books with track diagrams are easily available in the market. The same can also be searched on the internet.
  6. If the problem still not fixed then check Fuse, Coil and Regulator – one by one. Change if required.
  7. If the problem is still not solved then Heat or Change the Charging IC.
  8. Lastly Heat, Re-ball or Change the Power IC.

Important Note

  • If the phone shows “NOT CHARGING” then change the Battery and check. If the problem is not solved then remove the charging regulator (no need to change it).
  • If the problem is still not solved then change the R22.
  • If the problem is not fixed then remove the two SMD capacitor above the Battery Connector (No need to change).
  • If the problem still persists then change the Charging IC.
  • If the Phone Shows “FALSE CHARGING” then use a 3.6 Volt Zener Diode and do Direct Charging.
