1. Try another cable and adapter
Cables fail inside where you cannot see it. Borrow a known-good cable and wall adapter. If the phone charges with a different set, replace the cable first. It is the cheapest fix.
2. Look inside the charging port
Lint, dust, and pocket debris pack into the USB port over time. Shine a light in there. If you see compacted fluff, a technician can clean the port safely. Do not poke metal into the port at home. You can short the pins or push lint deeper.
3. Check the socket and power source
Wall sockets, extension boards, and cheap car chargers drop voltage. Plug directly into a wall socket you trust. If you only charge from a laptop USB port, try a proper adapter. Some phones need more power than a weak port gives.
4. Restart and watch for moisture warnings
Restart the phone. Some models block charging after a drop or humidity until you clear a moisture alert. If the phone got wet, stop forcing the charger. Dry it and bring it in before corrosion spreads.
5. Note what changed
Did charging stop after a fall, a new screen, or a cheap cable from the street? That detail helps a fundi wa simu narrow the fault fast. Charging issues after repair often point to the port flex or a loose connection, not the battery.
Bring the phone if cleaning and a new cable did not help, if the port feels loose, or if the phone only charges at an angle. We check the port, flex cable, and charging IC with computerized diagnosis before replacing parts.
