If your iPhone won’t charge, charges slowly or the cable feels loose, the fault is often the charging port — but try one free fix first: clean the port. Lint packs into the bottom of the Lightning port and is the single most common cause of “won’t charge”. If cleaning doesn’t help, a replacement charging port flex costs from £5.99. Here’s how to diagnose it.
Try this free fix first: clean the port
Direct answer: switch the phone off and gently remove lint from the Lightning port with a wooden or plastic toothpick (never metal). A surprising number of charging faults are just a compacted plug of pocket lint. Also try a different cable and plug to rule those out.
Signs the charging port flex needs replacing
- The cable only charges at a certain angle, or falls out
- No charging at all after cleaning and trying another cable/plug
- Very slow charging or it keeps connecting and disconnecting
- No data connection to a computer
- The microphone fails on calls (on models where the mic shares the port flex)
Which iPhone charging port part do you need?
The iPhone charging port is a replaceable flex cable — not soldered — so it can be changed without a soldering iron. Match your exact model, and note that on some models the flex includes the main microphone or a sub-board. Examples in stock: iPhone 12 / 12 Pro charging port flex from £5.99 and iPhone 11 charging port flex with microphone from £8.99. Prices vary by model and colour.
Is it a hard repair?
Replacing an iPhone charging port is a moderate repair: you open the phone from the screen, disconnect the battery, and remove the Taptic engine and some brackets to reach the flex. If you’re comfortable opening an iPhone it’s very doable; otherwise buy the part and have a technician fit it.
