✅ 30-Step Charging Solution Guide
Disassemble the Huawei P Smart 2019 safely.
Remove battery and check the USB port physically.
Clean the charging connector with IPA.
Check for bent or damaged USB pins.
Use multimeter in diode mode on VBUS and GND.
Trace VBUS line from USB to charging IC.
Check input filter/fuse/resistor for continuity.
If fuse is open, make jumper or replace.
Check voltage at battery connector pins.
If no voltage, suspect PMIC or charging IC.
Check capacitor near USB connector for short.
Remove USB jack and test its resistance.
Replace with a new Type-C/Micro USB jack.
Clean the pad area with solder wick.
Resolder with flux and proper alignment.
Test voltage after USB jack replacement.
If still no charge, check charging IC (usually near PMIC).
Heat and reflow the charging IC.
If short persists, remove the IC and re-test.
Replace charging IC with compatible model.
Use schematic or ZXW tools for tracing.
Reassemble motherboard.
Reconnect battery and power on.
Plug charger and observe charging animation.
Use amp meter to test charging current.
Should read between 1.0–1.5A for normal.
If slow charging, replace USB cable and charger.
Also check thermistor lines from battery.
Perform final charging test for 15 mins.
Problem solved — device charging normally!
