iPhone won't charge: cable, lint, or a dead charging port?
Most phones brought in for a dead charging port do not need a port. Here is the diagnosis order that finds the real cause before anyone quotes you for parts.
80% of dead ports
are compacted lint or a worn cable, and are resolved the same visit without replacing a part.
- Port cleaning is a same-visit job and usually no more than a diagnostic.
- Port flex replacement is quoted after inspection, typically under an hour on the bench.
- Wireless charging is a useful test: if it charges on a pad, the battery and board are fine.
Nine times out of ten it is not the port
An iPhone charging port is a connector with a row of very small pins, sitting at the bottom of a pocket-facing cavity. Lint, fabric dust and pocket grit compact into the back of that cavity over a year or two and stop the cable seating the last millimeter. The cable clicks, but the contacts never touch. That phone arrives described as a dead port and leaves with the original port still in it.
The second most common cause is the cable itself, followed by the charger brick, then a software or charging-circuit fault. The port itself being physically broken is real, but it is much rarer than the internet suggests.
How to check it yourself in two minutes
Do these five things before you drive anywhere.
- Shine a light into the port. Compacted lint looks like a felt floor at the back of the cavity.
- Try a different cable, then a different brick, then a different wall outlet. Test each separately.
- Put the phone on a wireless charging pad. If it charges, the battery and charging circuit are healthy and the fault is in the port or cable path.
- Wiggle the cable gently while watching the charging icon. Charging that cuts in and out points at the connector or cable, not the battery.
- Check whether the phone charges when powered off. Charging that only works off is an app or software issue, not hardware.
When the port really is the problem
If the port is packed with corrosion, has visibly bent pins, or the phone only charges at a specific angle no matter which cable you use, the port assembly is the likely culprit and gets replaced as a unit. On most models that is a self-contained flex, which means no board work and a fast turnaround.
There is a third category: the port is fine, the cable is fine, and the phone still will not recognize a charger. That points to the charging IC on the logic board, the component that negotiates power. Board-level work is quoted after inspection, and we explain the fault in plain terms before you decide whether it is worth it for the age of the phone.
What we do at the bench
The process is short and mostly about not skipping steps.
- Inspect the port cavity and contacts under magnification before anything is quoted.
- Clean compacted debris out properly with the right tools rather than a paperclip, which bends pins.
- Test charging at multiple wattages and check whether the phone negotiates fast charging correctly.
- Replace the port assembly when it is genuinely faulty, then retest charging and data transfer.
- Check battery health too. A tired battery can make a healthy phone look like it has a charging fault.
- If the fault is board-level, explain what failed and what the repair involves before proceeding.
What it costs
Cleaning and assessment start at the $49 diagnostic, waived if a repair goes ahead. Port and board-level repairs are quoted after inspection, before any work.

Common questions
What people ask before booking this repair
Get it fixed
Two ways to hand it over, one standard of work.
Drop off or meet up around Flemington for same-day service, or mail the device in from anywhere in the US. Phones are tested before and after, and you hear from a technician, not a call center.
