Symptoms
- Charging cable feels loose or falls out easily
- Charging is intermittent unless the cable is held at an angle
- Visible fuzz or debris inside the port when using a flashlight
- Charging stopped working after carrying the phone loose in a pocket
Likely causes
- CommonLint and dust from pockets or bagsFabric fibers pack into the port's small cavity and block the pins.
- PossibleSand or grit from outdoor useFine particles from beaches or dusty environments can wedge into the port.
- Less commonResidue from a case or screen protector packagingAdhesive or foam debris occasionally ends up in the port during setup.
What to do
- Power off the phone before cleaning to avoid any short circuit.
- Shine a flashlight into the port to see how much debris is present.
- Use a new, dry, soft-bristled brush (a small anti-static brush or a clean, unused toothbrush works) to gently sweep debris out.
- Alternatively, use a wooden or plastic toothpick to gently loosen packed lint, working slowly and never forcing it deeper.
- Tap the phone gently, port facing down, to help loosened debris fall out.
- Avoid compressed air, which can push debris deeper or damage the port.
- Avoid metal pins, paperclips, or needles, which can bend the internal contacts.
- Once clean, power on and test with a known-good cable.

When to call a pro
