Get “This accessory may not be supported” on iPhone? 7 ways to fix

Using counterfeit, frayed, or damaged accessories on your iPhone can trigger the “This accessory may not be supported” warning. Foreign particles on the accessory’s connector(s) or the device’s Lightning port can also cause this error.

Software-related issues are another factor worth mentioning. This post offers seven possible solutions to the same problem and warnings.

Specific warnings may vary depending on your iPhone model or operating system. “This accessory is not supported by this iPhone”, “This accessory may not be supported” and “Accessory not supported” are common variations of this error. However, their troubleshooting solutions are the same.

1. Reconnect the cable

Sometimes your iPhone may display a warning message due to an error. When an alert appears on the screen, tap ALRIGHT or Skip on the pop-up window and unplug the accessory. Wait a few seconds and reconnect the cable to your iPhone or iPad.

That may temporarily fix the problem, but the warning may reappear after a while — especially if the accessory fails.

Proceed to the next troubleshooting solution if the accessory is still not working on your iPhone and other devices.

2. Turn off or restart your iPhone

The error can also be caused by a temporary software glitch. Restart your iPhone if it keeps showing “This accessory may not be supported” when you plug in the charging cable.

Open Setting application, select Sharedclap Turn off and wait 30 seconds for your iPhone to turn off completely.

Then, plug the cable into the power adapter and connect the Lightning connector to your iPhone. If your iPhone won’t charge or restarts on its own, it’s possible that the charging cable or adapter is faulty or damaged. Restart your iPhone manually (press and hold the power button) and try the next troubleshooting.

3. Verify accessory compatibility

Not all Apple accessories work on your device, especially if you have an older iPhone or iPad. If the warning keeps popping up, your iPhone doesn’t support the accessory. Connect the accessory to other devices and check if it is still in good condition.

Contact the manufacturer if you are unsure about the compatibility of the accessory with your iPhone.

4. Clean your charging cable and power adapter

Your iPhone may charge slowly or not at all due to foreign particles causing interference. Check both ends of the charging cable and make sure there is no dirt, debris, lint or dirt in and on their surface.

Unplug both ends of the cable from your iPhone and the power adapter. Then, use a soft, dry, lint-free cloth to wipe the cable’s Lightning connector. You can also use a cotton swab or paper towel to dry, but be careful not to leave residue. To clean the USB connector, plug in a soft toothbrush and gently stroke the bristles horizontally. That will remove dirt, junk, and other particles from the connector.

You should also check the USB port on the charger (power adapter) for foreign particles. Next, clean the charger’s USB port, attach the Lightning cable, and charge the iPhone. If the warning reappears, plug the charger into a different power source and check if that solves the problem.

Avoid cleaning your accessories with any liquid material — not even water. That can corrode or damage the metal contacts on the USB and Lightning connectors. Refer to this Apple Support document for detailed instructions on how to clean Apple products and accessories.

5. Clean your iPhone charging port

Foreign particles in your iPhone’s charging port can cause the “This accessory may not be supported” error. Check your iPhone’s charging port with a flashlight and remove any foreign objects you find.

Spray compressed air from the air dust filter (canned air) into the port. It’s a safer method of removing dirt from tiny spaces in electronics without damaging delicate components.

Alternatively, you can insert a flat toothpick or pointed cotton swab into the port and gently clean the foreign objects. Avoid cleaning the port too quickly or too vigorously, so you don’t push particles deeper into the gate.

Again, do not use sharp or metal objects (pins, paper clips, needles, etc.) to remove foreign particles from your iPhone port. They will damage the metal contacts in the port. Likewise, do not blow air from your mouth into the port. The breath that comes out of your mouth contains moisture or water droplets that can damage your iPhone.

6. Try a different accessory

Apple recommends charging your iPhone (and iPad) with original accessories. So make sure you use charging accessories from Apple’s online store or offline stores.

If you’re using an original Apple Lightning to USB cable, check it for any of the words below:

  • Designed by Apple in California. Assembled in China
  • Designed by Apple in California. Assembled in Vietnam
  • Designed by Apple in California Indústria Brasileira

The 12-digit serial number must also be at the end of these lines. Third-party cables do not have inscriptions. Therefore, pay attention to a For Apple (MFI) labels or certifications on non-Apple charging accessories. You will find labels on the packaging of certified third-party accessories.

If the cable doesn’t have a serial number or MFI label, it’s a fake. There are many third-party accessories with fake MFI labels. Therefore, we recommend that you use Apple’s accessory finder to confirm if your charger or cable is MFI certified.

Open the tool in your web browser and search for your cable on Apple’s database using your brand name, model number, Universal Product Code (UPC), or European Article Number (EAN) . You will find these numbers/codes on the cable’s packaging or the product page on the manufacturer’s website.

We also recommend that you read Apple’s support documentation on identifying counterfeit or uncertified charging accessories.

7. Update your iPhone

According to Apple, some accessories may require the latest version of iOS to function properly. Install the latest iOS update on your iPhone if none of these fixes stopped the error.

Connect to a Wi-Fi network, go to Setting > Shared > Software updatesand press Download and install to update your iOS device.

Contact Apple Support

If your iPhone shows a warning without any accessories connected, the Lightning port may be filled with foreign particles. Cleaning the gate will stop the warning — refer to method #4 above for instructions. Contact Apple Support or visit a nearby Apple Store if the problem persists.
