If your iPhone won’t charge, you’re not alone. A charging port that doesn’t work properly is one of the most common issues iPhone owners face. The good news is that not every problem requires an expensive repair. Sometimes the fix is as simple as cleaning the port or swapping out a cable. Other times, the charging port itself may be damaged and need professional repair.

Let’s go through the most common causes, quick DIY checks you can try at home, and when it’s time to bring your iPhone to a repair shop

Common Reasons Your iPhone Won’t Charge

There are several possible causes when your iPhone is not charging or the charging port isn’t working properly:

  • Lint or dust inside the port: Pockets are the number one enemy of iPhone charging ports. Lint and dust get packed inside the port and prevent the cable from making full contact.
  • Bent or damaged pins: The tiny metal connectors inside the port can bend or wear down over time. If they do not line up correctly, your phone will not charge consistently.
  • Liquid damage: Even a small amount of moisture can corrode the charging port and cause permanent damage.
  • Logic board issues: In rare cases, the problem is not the port at all but the phone’s logic board. This requires a board-level specialist, not just a simple port replacement.

👉 Pro tip: A charging port usually needs replacement if the pins are worn out or there is visible liquid damage. If it is a board issue, replacing the port will not fix the problem.

Quick DIY Checks Before Replacing the Charging Port

Before rushing to replace your iPhone charging port, try a few simple DIY steps:

  • Test a different cable and adapter: A worn-out cable or faulty adapter is one of the most common reasons an iPhone won’t charge. Always test with an Apple-certified cable and charger.
  • Try another outlet or power source: Rule out the wall socket or power strip by plugging into a different outlet or using a computer USB port.
  • Check the fit of your charging cable: If the cable doesn’t fit snugly, your port may be clogged with dust or lint.
  • Clean the charging port carefully: Use a wooden toothpick or a soft anti-static brush to gently remove debris. Never use metal objects, as they can damage the pins.

👉 If you’re not comfortable cleaning it yourself, most repair shops (including us) offer a professional charging port cleaning service for around $25.

When to Bring It to a Repair Shop

If the above steps do not solve the issue, it is likely time to let a professional take a look. Bring your iPhone in for repair if:

  • Cleaning and cable swaps did not help
  • The port feels loose or physically damaged
  • The phone only charges when you wiggle the cable
  • There are signs of liquid damage
  • The phone still will not charge after all DIY steps

At that point, the charging port may need replacement, or the issue could be deeper on the logic board.
