Steps

  1. Turn the phone off completely. Hold the power button and tap Power off, then wait for the screen to go dark.

  2. Lay out 100% isopropyl alcohol and a brush with flexible bristles around 2 to 3 cm long. A soft toothbrush works if you do not have one.

  3. Spray or dip the brush until the bristles are wet but not dripping. Shake off any excess over a paper towel first.

  4. Push the brush into the port and make 10 to 15 strokes in one direction only. Keep the strokes light so you do not bend the pins.

  5. Turn the phone around and repeat with 10 to 15 strokes from the other side, so both rows of contacts get cleaned.

  6. Repeat the full brushing two or three times if the port is badly clogged. Re-wet the bristles between rounds.

  7. Slide a plastic pick with a hook into the bottom of the port and pull out any hard dirt left behind. Never use a metal pin or needle.

  8. Set the phone aside for 10 to 15 minutes so the alcohol evaporates completely. Check the port looks dry before you power it on.

  9. Plug in your charger and confirm the phone shows it is charging. If it still will not charge, try a different cable before cleaning again.

Tips and common mistakes

Never poke the port with a metal pin, needle or SIM tool, as it can short the contacts.

Skip compressed air, which can push lint deeper into the port instead of clearing it.

Do not turn the phone on until the alcohol has fully dried, and keep it away from flames.

Clean the port every few months if you carry the phone in a pocket or bag.

Questions

What alcohol should I use to clean a charging port?

Use 100% pure isopropyl alcohol. It dissolves grime and evaporates fast, while water-based cleaners can leave moisture inside the phone.

How long should I wait before turning the phone back on?

Wait about 10 to 15 minutes after the last brush stroke. The port should look and feel dry before you press the power button.

Can I use a toothpick instead of a plastic pick?

A wooden toothpick is a reasonable substitute, but avoid anything metal. A plastic pick with a hook reaches the compacted dirt at the bottom more easily.
