A dead battery can be a real drain on your plans—especially when your iPhone® refuses to charge or sync like it should. Whether it’s stuck at 1% or won’t connect to your laptop, the USB-C port might be the problem.

At Asurion, we help our millions of customers troubleshoot their tech every day. Here’s how to figure out what’s going wrong with your iPhone’s USB-C port—and how to fix it without making it worse.

Start with the basics

Before digging into your phone’s settings or hardware, double-check:

• You’re using an Apple-certified USB-C to USB-C cable and charger.
• The outlet or power source is working.
• The cable works on another device.
• Your iPhone is running the latest version of iOS.

If you’ve tried all that and still no charge, it’s time to look closer.

Clean your USB-C port

Dust, lint, or pocket fuzz in the port is one of the most common reasons an iPhone won’t charge or sync. Even a tiny piece of debris can block the connection.

• Turn off your iPhone.
• Use a soft-bristled brush or toothpick to gently clear out the port.
• Avoid using anything metal or sharp.
• Try a can of compressed air to blow out stubborn dust.

Follow our step-by-step guide on how to clean your charging port if you need a visual walkthrough.

Restart your iPhone

It sounds simple, but restarting your device can fix temporary software glitches.

• Press and hold the Side button and either Volume button until the power-off slider appears.
• Drag the slider to turn it off.
• Wait 30 seconds, then press and hold the Side button again to turn it back on.

Now plug in the charger and check for the lightning bolt icon.

Try a different cable or charger

If cleaning didn’t help, try charging with a different cable and power adapter. If it starts working again, the original cable or charger might be the issue.

If your iPhone still isn’t charging or syncing after all these steps, the USB-C port might be loose, damaged, or worn out. That kind of hardware issue won’t be fixed with cleaning or restarts.
