iPhone Won't Charge? How to Fix a Charging Port That's Not Working
You plug in your iPhone and… nothing. No charging symbol, or it charges painfully slowly, or it cuts in and out. Before you assume the worst, know this: the most common cause of an iPhone that won't charge isn't a broken port — it's lint packed into the charging port. This guide takes you through every fix in order, from the 30-second checks to when you genuinely need a repair.
Start with the quick checks
- Try a different cable and adapter. Cables fail internally far more often than ports. Test with a known-good Apple or MFi-certified cable.
- Try a different power source. Swap the wall outlet, and try a wall adapter instead of a laptop USB port — laptops and some car chargers deliver too little power.
- Force restart the iPhone. Press and release Volume Up, press and release Volume Down, then press and hold the Side button until the Apple logo appears. This clears software freezes that block charging.
Clean the charging port (the #1 real fix)
Lint, pocket fuzz and dust compact into a hard plug at the bottom of the port, physically stopping the cable from seating. Here's how to clean it safely:
- Power the phone off first.
- Use a wooden or plastic toothpick — never metal, which can short the contacts or scratch them.
- Gently scrape along the bottom and sides of the port and hook out the debris. You'll often be surprised how much comes out.
- Finish with a short burst of compressed air held a few centimetres away.
Plug in again after cleaning — for many people, this alone solves it.
Rule out software and liquid
- Update iOS. Settings → General → Software Update. Charging bugs do happen and get patched.
- Watch for a "liquid detected" alert. If your iPhone detects moisture in the port, it blocks charging to protect itself. Unplug, dry the phone in a ventilated spot for a few hours, and try again. Do not override the warning while it's wet.
- Try wireless charging (iPhone 8 and later). If it charges wirelessly but not by cable, the problem is the port or cable — not the battery.
Inspect the cable and adapter
Look closely at both ends of the cable for fraying, kinks or discolouration. Cheap non-certified cables are a frequent cause of "charges sometimes" behaviour — and can damage the phone. Stick to Apple or MFi-certified accessories.
When you need a professional repair
If you've tried different cables and adapters, cleaned the port thoroughly, restarted, and ruled out liquid — and it still won't charge — the issue is likely hardware:
- A damaged charging port (dock connector) — bent pins or a loose connection from a drop. This is a common, affordable repair.
- A failing battery — if it charges but drops instantly or won't hold a charge, check Battery Health.
- A charging IC fault on the logic board — rarer, needs a specialist, but repairable by an experienced technician.
A port replacement is one of the cheaper phone repairs and usually done same-day, so don't rush to replace the whole phone.
Frequently asked questions
Why does my iPhone charge only when I hold the cable at an angle?
That's a classic sign of either a worn cable or a loose/dirty port. Clean the port first; if it persists with a new cable, the port connector is likely worn and needs replacing.
Is it safe to clean my charging port myself?
Yes, if you power the phone off and use only a wooden or plastic toothpick and compressed air. Avoid metal tools, liquids, and jabbing hard — you only need to lift out the lint.
My iPhone says "This accessory may not be supported." What does that mean?
It usually means a non-certified cable, a damaged cable, or moisture/debris in the port. Try a certified cable and clean the port before assuming a hardware fault.
Cleaned the port, swapped the cable, and it still won't charge? A worn charging port is one of the most common — and most affordable — phone repairs. A technician can test and replace it quickly.
