Unveiling the Predicament of a Non-Charging Mobile Phone Battery – Effective Remedies for Resolving Charging Issues with Removable and Non-Removable Batteries

Discovering Solutions for a Mobile Phone Battery That Refuses to Charge

In the realm of mobile technology, the charging section plays a pivotal role in replenishing the battery’s energy. This crucial domain is under the jurisdiction of the Charging IC or Power IC, constituting an integral part of a mobile phone’s PCB Power Section.

Unveiling the Challenges Encountered When a Mobile Phone Battery Fails to Charge

  1. Total Absence of Charging Activity:
    • The mobile phone battery exhibits no signs of charging whatsoever.
  2. Deceptive Charging Indicator:
    • Despite displaying a charging indicator, the battery remains stagnant, devoid of any charging progress.
  3. Persistent “Not Charging” Message:
    • Upon plugging in the charger, the device stubbornly insists on displaying a “Not Charging” message.
  4. Troublesome Connectivity:
    • When the charger is connected, the mobile phone falters in establishing a reliable charging connection.
  5. Excessive Heat Generation:
    • The mobile phone experiences undue warmth when connected to the charger, raising concerns.
  6. Inadequate Charging Performance:
    • The phone’s charging capability falls short of expectations, resulting in prolonged charging durations.
  7. Incomplete Battery Charge:
    • Even after extended charging periods, the battery refuses to reach a full 100% charge in Android devices.

Resolving the Mobile Phone Battery Charging Impasse

Follow these Sequential Steps:

  1. Charger Replacement:
    • Begin by substituting the charger and assessing the voltage, which should ideally range from 5 to 7 Volts.
  2. Charger Connector Maintenance:
    • Clean, re-solder, or replace the charger connector, as it may be a source of the issue.
  3. Battery Replacement:
    • If the problem persists, contemplate replacing the battery. For non-removable batteries, exercise caution while detaching them, as they are affixed to the phone’s base.
  4. Battery Connector Voltage Check:
    • Utilize a multimeter to measure the voltage at the battery connector, aiming for a reading between 1.5 to 3.7 DC Volts.
  5. Charging Section Inspection:
    • In the absence of voltage at the connector, investigate the charging section’s circuitry. Refer to the specific mobile phone model’s diagram, or consult readily available books and online resources.
  6. Fuse, Coil, and Regulator Examination:
    • Inspect and replace these components individually if necessary, addressing potential issues step by step.
  7. Charging IC Evaluation:
    • If all else fails, consider heating or replacing the Charging IC as a potential solution.
  8. Power IC Consideration:
    • As a last resort, explore the possibility of heating, reballing, or replacing the Power IC.

Essential Considerations

  • In cases where the phone persistently displays “NOT CHARGING,” first replace the battery before considering charging regulator removal (without replacement).
  • If the issue lingers, contemplate replacing the R22 component.
  • In scenarios where the problem remains unresolved, you may need to remove the two SMD capacitors located above the Battery Connector (without replacement).
  • If all else fails and the issue persists, resort to changing the Charging IC.
