Android Charging Problem Spark 5 Pro.

PROBLEM: Show charging but not charge battery nor increase current.

SOLUTION: First we check the input current on the diode which will be 5.2 volts etc.

After that, check the output current on the capacitor next to the charging IC which will be 4.2 volt, etc.

If the output is low, then change the charging IC.

If the output is full, check the resistor, if it is bad, change it.
