Phone won't charge — pocket lint vs a failed charging port

A phone that won't charge, charges only at a certain angle, or needs the cable "just so" is one of the most common repairs I see — and the cause is usually one of two things.

Most common: pocket lint

Your phone lives in a pocket or a bag, and the charging port slowly fills with compressed fluff and dust. It forms a solid plug at the bottom of the socket, so the cable can't seat fully against the contacts. The signs:

  • The cable feels loose, or doesn't "click" in like it used to.
  • Charging only works if you hold the cable at an angle or press it in.
  • Wireless charging still works fine (the port isn't in that path).

A careful clean-out — done with the right tools, not a pin or a cocktail stick — often fixes this completely for very little.

A wad of compacted grey pocket lint just pulled from a phone's charging port, lying on the bench beside the phone and a fine metal pick tool.
I always try a clean first — a genuinely failed port is a separate, board-level repair.

Next most common: a damaged charging port

If a clean doesn't do it, the port itself may be worn or damaged — bent, corroded or burnt pins, liquid damage, or a socket that's physically worked loose from the board. Tell-tale signs:

  • No charge at all with a known-good cable and plug (try more than one of each).
  • The phone gets warm at the port but doesn't charge.
  • The port visibly wobbles, or you can see debris or green corrosion inside.

On most phones the charging port is either a replaceable flex assembly or soldered to the mainboard. Where it's soldered, it's a board-level repair — the old port off with hot air, a new one fitted and tested.

Rule out the simple stuff too

A frayed cable, a tired plug, or a worn-out battery can all look like a charging fault. Bring the phone in and I'll test the whole path and give you a fixed quote — often it's the cheap clean, and I'll tell you straight if it is.
