Now that you know the causes for seeing “This Accessory may not be supported” message on your iPhone, let us dive right into the possible fixes.

Solution 1: Ensure that the cable is MFI Certified

As stated earlier, MFI certified stands for Made For iPhone/iPad/iPod, and it means that the accessory has been certified to work with Apple products. If the cable you are using on your iPhone is not MFI-certified, a prompt error will appear. 

To solve this problem, try as much as possible to use the original cables that were included with your iPhone. Still, if you opt to use third party cables, see to it that they are MFI-certified. The easiest way to know whether a product is MFI certified is by checking if its packaging has the “Made for iPad” or “Made for iPhone” badge. Also, MFI certified cables can sometimes have a 12-digit serial number and a smooth, consistent appearance.

However, if you cannot locate the accessory’s packaging or the serial number, you can search whether it is MFI certified or not here.

Solution 2: Examine Your Lightning Port

After inspecting your accessories and ensuring that they are in the MFI certified, it is now time to inspect your lightning port where you connect the lightning cable. Any dirt, debris, or gunk that is stuck inside the lightning port is likely to affect the connection between your phone and the accessory. Use a flashlight to thoroughly inspect the lightning port and then clean the inside using a toothpick. Be careful while doing this to prevent internal damage. Once done, try charging the phone.

Solution 3: Update the Latest Version of iOS

It is recommended to update your device to the latest version of iOS. This is because some accessories, particularly those made by Apple, may require the latest and updated versions before they can connect. To do this:
  • Go to Settings
  • Click on General
  • Then click om Software Update
  • If there is a new update available, click on Download and Install

Before undertaking this procedure, it is important to ensure that your iPhone has at least 50 percent battery life or is charging. 

Solution 4: Reset All Settings

Incorrect settings can trigger some errors on the iPhone device as well. Doing an all-settings reset would be ideal if the error appears after doing a customization of your phone’s settings. By doing a reset of the settings, you will be able to remove the auto-update overrides and all customized settings to help correct the errors.
  • Go to Settings
  • Click of General and then Reset
  • On the Reset tab,tap on Reset all settings
  • Enter the passwords of your device and confirm to reset all settings on your device

After performing the reset, you phone will automatically reboot before loading up the default options. 

Solution 5: Reboot your iPhone

In most cases, restarting your phone or doing a soft reset will likely do the trick. This can help to clear out minor errors in your system, including the “This accessory may not be supported” error.

To do a soft reset or reboot for your iPhone, follow these steps below:

Reboot for iPhone 7 or iPhone 7 plus:Press and hold the volume down button and the side switch button for about 10 seconds until the Apple logo appears.

Solution 6: Turn on Airplane Mode

It might seem simple, but turning on the Airplane mode on your device could do the trick. Once you have turned it on, power off your device and then turn it on in two minutes time, but with the accessory attached.
