Symptoms
- Phone doesn't charge or charges only in certain cable positions
- Charging icon flickers on and off
- No response at all when plugged in
Likely causes
- CommonLint or debris blocking the portPocket lint compacts inside the port and blocks the pins from making contact.
- CommonBad cable or wall adapterFrayed or cheap cables are a very common cause mistaken for port damage.
- PossibleBent or damaged pins inside the portUsually from inserting a cable at an angle or a drop.
What to do
- Test with a different cable and wall adapter you know work on another device.
- Look inside the port with a flashlight for lint, dust, or a bent pin.
- Power off the phone and gently clean the port with a wooden toothpick or a dry, soft brush — never metal.
- Try compressed air in short bursts to blow out debris.
- Wiggle the cable gently while plugged in to see if a specific angle makes it charge, which points to a loose port connector.
- If a known-good cable and cleaning don't help, the port likely needs professional repair.
