Many users have reported a similar issue and didn’t know how to resolve it. This guide will show you how to fix the “accessory not supported” error on iPhone.

Reasons the iPhone accessory is not supported

First, let’s understand why the iPhone accessory is supported. The reasons include:

  • The accessory is counterfeit (not MFi-certified).
  • It is corroded.
  • The iOS software has a malfunction.
  • The lighting port is dirty, damaged, or broken.
  • A connecting cable is dirty, damaged, or broken.
  • The power adapter is defective.
  • It is not compatible with your iPhone.
  • The accessory is outdated

Using the steps below, you can easily diagnose the cause of the error message and fix it immediately.

2. Restart your iPhone

Next, you should restart your iPhone to fix software glitches that might prevent your device from connecting to the accessory.

For iPhone 8 and earlier models, press and hold the power button until the power icon appears on the screen. Swipe it to the right to turn Off the device.

For iPhone X and later models, press and hold the power button and volume buttons until the power icon appears on the screen. Swipe it to the right across the screen to switch off the device.

After 30 seconds, press and hold the power/side button to turn On your iPhone.

Try and connect your accessory again. If the iPhone charger is not supported error message doesn’t appear, then the software glitch is fixed. If it pops up, move on to the next fix.

3. Get an MFi-Certified accessory

Using a poor-quality cable is one of the main reasons your iPhone charger is not supported. Understandably, the original iPhone accessories can be expensive.

But, the cost pales compared to the damage a third-party cable might do to your device. Also, there’s the frustration of always receiving the “iPhone accessory is not supported” error message.

4. Clean the port and cable

After using your iPhone for a while, it collects pocket lint from carrying it in the pocket, magnetically-attracted debris, and dust. These accumulate in the charging port, making it difficult for the cable to fit snugly inside and connect properly. Hence “the accessory may not be supported” error message.

To solve this, you need to clean the port regularly. First, turn Off your iPhone to avoid unnecessary damage. Next, take a toothpick, push pin, paper clip, or fold a paper and use it to extract foreign objects inside the charging port. Finish by blowing air into the port to force out the remaining dirt.

Also, you must clean the cable’s pin to remove dirt and corrosion. Use an anti-static brush or new toothbrush and a little alcohol. Remember to wipe it with a dry cloth once you’re done.

5. Update iOS

If the error message is because of a software bug or glitch, then an iOS update will solve the problem. To update to the latest iOS version, follow the steps below:

  • Launch the “Settings” app.
  • Tap on “General”.
  • Go to “Software Update” and look for available updates.
  • Download and install the update.
  • You should enable automatic updates to save yourself from the manual update hassle. The iPhone will notify you before installing any new updates.

6. Enable airplane mode

For this fix, use the following guide:

  • Connect the accessory to your iPhone.
  • Dismiss or ignore the error message when it appears.
  • Enable Airplane mode on your iPhone.
  • Switch off your iPhone, wait for one minute, then turn it On.

7. Ensure the accessory is compatible

When dealing with a new accessory, ensure it’s compatible with your device. Some accessories are specifically for certain iPhone models.

8. Check the power adapter

The error message could spring from your iPhone’s power supply unit. Either the adapter is not working, or the USB port doesn’t provide enough power to charge the iPhone.

In that case, you’ll have to change the adapter or try and use alternative charging options like the power bank.

9. Inspect your accessory

If your accessory is MFi-certified but still gives you the “accessory may not be supported” error, then it could be due to damage. Inspect the cable for physical damages or any form of wear and tear.

To be sure, try and use another MFi-certified accessory.

10. Talk to Apple Support

At least one of the troubleshooting solutions above will help you eliminate the error message “this accessory may not be supported.” However, you should reach out to Apple Support if it still appears. They’re better positioned to diagnose the issue and offer durable solutions.

With an AppleCare plan, you could get a replacement accessory at no cost. Talk to the experts and let them inform you about your options.
