Way 1: Examine Your iPhone Charger

If your iPhone is saying this accessory may not be supported when you are trying to charge the device, there is great chance that the issue is caused by a defective charger.

So, the very first thing you should do is to inspect the charger thoroughly. If any physical damage is visible then you may have found the cause but if there isn’t any visible damage, you need to look further into software glitches.

Clean the charger and even try to charge the device using other chargers. If your iPhone does not say charging is not supported with this accessory on other chargers then it is a definite issue with the charger. You need to replace it immediately.

Way 2: Clean up Charge Port

Suppose you didn’t try to out different chargers on your iPhone, instead you used the same charger to charge a different device and it is working. Then, the problem must be with the device itself.

First, you need to check the Charge Port on your iPhone. It is possible that because of too much dirt the charger is not connecting properly. So, get a small brush and clean the port properly. It is possible all this might be due to a clogged port and cleaning it would fix the issue instantly.

Way 4: Check for Any Software Update

It is also possible that updating the iPhone to the latest iOS 16 will fix the issue, of course, if it a software issue. You can look for available updates and if there is any. Generally, there are 2 ways to update the device: via OTA or iTunes.

Step 1: Try to connect the device using the USB cable provided by Apple, it will work faster.

Step 2: iTunes will detect the device immediately, run the app.

Step 3: Go to “Summary” and click on “Check for Update”.
