Phone won't charge, or has to be wiggled at the perfect angle? The most common cause isn't a broken port, and the fix is often under £20.
You plug your phone in. Nothing. You wiggle the cable. The charging icon flickers on and off. You buy a new cable, then a new charger, and the problem stays. You're convinced the port is fried.
It probably isn't. Here's what's almost always actually going on, and how to fix it for a lot less than a port replacement.
A charging port is a small metal cavity that you carry around in a pocket all day. Lint, dust, biscuit crumbs and microscopic fibres get packed into the bottom of it, slowly building up a layer that prevents the charger from making proper contact.
The symptoms:
If you're seeing any of these, the port is probably fine. There's just a sticky plug of lint between the connector pins and your cable.
Shine a phone torch into the port from a few centimetres away. Look for:
Don't try to clean it with a metal pin, paperclip, or needle. You can short out the pins, scrape protective coating off them, and turn a £15 cleaning job into a £39+ port replacement.
We use a non-conductive tool, a low-pressure puff of clean air, and isopropyl alcohol on a tiny brush. The process takes about 15 minutes. Most of the time the customer can see the chunk of fluff that came out. They're often surprised at the size.
A charging port cleaning is £15 at our Birmingham lab. That's it. If it turns out the port is genuinely damaged, the diagnostic is included in the quote for the next stage of repair.

There are a few scenarios where the port itself has had it.
All charging port work comes with a 6-month warranty.
Worth a 5-minute home check first.
If after all that the port is still flaky, bring it in. A 15-minute clean might be all you need.
It's fine short-term. But it's slower, generates more heat (which ages the battery faster), and you can't move data over the cable. That means iTunes/Finder backups stop working, certain accessories stop working, and CarPlay over cable stops working. Treat it as a stopgap while you book a proper port fix.
Why does my phone say "Liquid detected in Lightning connector" when it's dry? This iOS warning often persists after water exposure even once the port has dried, because residue inside continues to read as moisture. A professional port clean removes it. If it keeps coming back, you may have corrosion on the contacts that needs micro-cleaning.
Will using a cheap charger have damaged the port? The port itself, no. But a non-spec charger can spike the charging IC on the logic board, which is a much more expensive failure. Stick to MFi-certified accessories.
My phone charges with one cable but not another. Is the port broken? Almost certainly not. Cables have wildly different tolerances. If a fresh, known-good cable works fine, your old one is failing.
Should I just live with a flaky port? Three reasons not to. One: one day it'll stop entirely. Two: intermittent connections generate heat and accelerate battery ageing. Three: a £15 clean now is much cheaper than the IC repair you'll need if the port shorts.
