Why iPhone Says “This Accessory May Not Be Supported”

Before we get to the solutions, it may be important to take a look at some of the reasons why your iPhone showing you this error. Actually, there is a variety of reasons why your iPhone says “This accessory may not be supported” and some of the most common ones include the following:

  • The accessory is not supported by your iPhone or iPad.
  • The iPhone’s software could be malfunctioning.
  • It is also possible that the accessory is dirty, damaged or broken.
  • The lightning port on the iPhone is dirty, damaged or broken.
  • The charger itself could be broken or damaged.

The following are just some of the solutions you can try to fix this accessory may not supported error on your iPhone/iPad:

Way 1: Change to an MFi-Certified Cable

If this problem occurs immediately after plugging the iPhone into a power source, it is possible that the cable you are using to charge the device is not MFi-certified. This means that the cable doesn’t meet Apple’s design standards. If you purchased the charging cable at an unauthorized store for a few bucks, then it is likely that it was cheaply made and not certified to work with Apple products. These cables can cause damage to your device and cause the voiding of the warranty.

The best way to fix this issue therefore is to charge your iPhone with the origianl cables or purchase an Apple recommended charging cable.

Way 2: Clean the Accessory and the Port

It is also important to make sure that both the accessory and the port on the iOS device are free from dust and dirt. To clean the accessory, disconnect it from the device and turn off everything, then use a microfiber cloth to rub at the surface to remove lint, dust or dirt that may be on the accessory. You can also use the standard pencil eraser and a lint-free cloth or electronic cleaning cloth to clean the port.

Way 3: Restart Your iPhone

If changing your cable and cleaning the port doesn’t work, then it is likely that the problem is software related. In this case, the simplest solution to try is a restart of your iPhone. A restart of the device will refresh the software components and fix the device.

To restart your iPhone, simply press and hold the power button (the side button on iPhone X and earlier) until the “slide to power off” slider appears. Slide to turn off the device, wait a few seconds and then press the power button again until the device power on.

Way 4: Reset All Settings on iPhone
