Steps

  1. Power off your phone and unplug the charger before you touch the port.

  2. Shine a flashlight into the port and look for grey fluff, dust or lint packed against the back wall.

  3. Give the port two or three short bursts of compressed air. Hold the can upright and keep the nozzle a few centimetres away.

  4. Slide a wooden toothpick along the inside walls to hook out lint. Work slowly and never push toward the metal pins.

  5. Lift stubborn fluff with a plastic dental pick or the flat end of the toothpick. Skip metal pins, needles and paper clips.

  6. Turn the phone port facing down and tap it gently against your palm so loose dust drops out.

  7. Brush the port walls with a clean, dry soft toothbrush to sweep out what is left.

  8. If you used a drop of isopropyl alcohol on the brush, let the port dry for at least 10 minutes before charging.

  9. Plug in a known-good cable and charger and check that the charging icon appears. Try a second cable if it does not.

Tips and common mistakes

Never dig into the port with a metal pin, SIM tool or paper clip, as it can bend the charging pins.

Do not spray liquid cleaner or water into the port, and never blow into it with your mouth because moisture causes corrosion.

If the phone still only charges at a certain angle after cleaning, the cable or the port itself is likely worn and needs a repair shop.

Clean the port every few months if you carry the phone in a pocket or bag without a case cover.

Questions

Can I use a vacuum cleaner to suck out the dust?

Yes, but use a small nozzle on low power and keep it a few centimetres away. Strong suction close to the port can damage the internal pins.

Is isopropyl alcohol safe inside the charging port?

A small amount of 90 percent or higher isopropyl alcohol on a brush is fine because it evaporates fast. Let it dry fully before you plug anything in.

How do I know if the problem is the port or the cable?

Test with a different cable and charger first. If the phone charges normally with another cable, replace the cable. If nothing works, the port needs a repair.
