Charging ports: lint, sideways force, and the repair you may not need
The short answer
Most phones that arrive not charging have nothing broken. Pocket lint compacts at the bottom of the port a little further with every cable insertion until the plug cannot reach the pins. A careful clean with a wooden toothpick, phone switched off, fixes a large share of them.
What is actually in there
A charging port is a small metal shell with contacts at the back, and the shape of it is a lint trap. Every time a phone goes into a pocket it collects fibres, and every time a cable goes in those fibres get pressed further down and packed harder.
Eventually the compacted plug of lint is thick enough that the cable stops short of the contacts. The phone charges intermittently, then only at an angle, then not at all. Nothing has broken; the connector simply cannot reach.
Shine a bright light straight into the port and look. A healthy port shows a clean metal tongue or a row of contacts at a consistent depth. A blocked one shows grey felt.
Cleaning one without wrecking it
What not to do: compressed air, which pushes debris deeper and can carry moisture; anything metal; and any liquid at all. Bent pins turn a free clean into a paid replacement, and that is genuinely the most common way a cleanable port becomes a repair.
- Switch the phone offNot standby. Off. This matters if anything metallic is going near the contacts.
- Use a wooden toothpickWood is softer than the contacts. A pin, a paperclip or a SIM tool is harder than the pins and will bend them.
- Scrape, do not stabWork the point down one wall of the port and drag toward you, rather than pushing into the middle.
- Empty it repeatedlyIt comes out as a compressed grey wad, often surprisingly large. Keep going until nothing more comes out.
- Test with a good cableThen, if it works, do it every few months rather than waiting for it to fail again.
When it is not lint
That last one is a useful test if the phone supports wireless charging, because it separates the port from the battery in ten seconds and it costs nothing.
- It charges from a plug but a computer will not see it: data pins rather than power pins
- The cable falls out on its own with a clean port: worn retention, and that is a replacement
- It only charges held at an angle and the port is clean: worn or damaged contacts
- It got hot around the port while charging: stop, and get it looked at before it takes the board with it
- It stopped after the phone got wet: corrosion, and do not keep plugging it in
- It charges wirelessly but not by cable: confirms the port rather than the battery
Why they wear out in the first place
Sideways force. A connector is designed to take a plug straight in and nothing else. Charging with the phone in a pocket, lying on a bed with the cable under tension, or a car mount that pulls at an angle, all lever the port against its solder joints.
Cheap and damaged cables. A plug with a bent or discoloured connector scrapes the contacts every time it goes in, and a cable that runs hot is heating the port at the same time.
And the fast charging standards push real current through a small connector. A port that has started getting warm is worth looking at rather than living with.
What a replacement involves
On many phones the port is on its own flex assembly that unplugs, which makes it a straightforward same-day repair. On others it is soldered directly to the logic board, which means hot air, a microscope and a steadier hand, and it is bench work rather than counter work.
Which one yours is depends on the model, and it is the main reason the price varies more between phones for this repair than for a screen.
Either way, a port repair does not touch your storage. Nothing on the phone is at risk from it.
Common questions.
Most often compacted pocket lint stopping the cable reaching the contacts. Rule out the cable and the plug first, then look into the port with a bright light. A clean fixes a large share of the phones that arrive here not charging.
It varies more between phones than a screen does, because on some models the port is a plug-in flex and on others it is soldered to the board. Your model's page carries the figure, and the diagnostic tells you which yours is before anything is ordered.
Yes, on phones, tablets and laptops. USB-C carries real current through a small connector, so a port that has started to feel loose or run warm is worth looking at early rather than after it fails.
Yes. Lightning is on every iPhone up to the 14 and plenty of iPads, and we will keep repairing them for as long as people have them.

Carefully, with the phone switched off and a wooden toothpick. Never a pin, a paperclip or a SIM tool, and never compressed air. Bent pins turn a free clean into a paid replacement.
The data pins have failed while the power pins still work. Same port, different contacts, and it tells us which part of it has gone.
