How To Fix Unlock iPhone To Use Accessories Charger Not Working

We’re currently not sure if these are just some isolated cases, or if an iOS 16.2 bug is triggering the Accessory Connected notification, but here is what you can do to solve it:

1. Clean Parts

This problem has been reported in the past, in iOS 15 too and it’s been usually related to a faulty charging cable or dirty charging port.

First, clean your iPhone’s charging port using a toothbrush, toothpick or a special cleaning tool like this one.

Tip: You can use the same multi-tool for cleaning the Lightning plug, or use a soft wipe.

2. Replace Cable

If the issue persists, replace the Lightning to USB-C cable. Make sure that you use a genuine accessory.

Fact: Aftermarket chargers could also trigger the USB Accessory notification and even the Liquid detected in Lightning connector error!

Tip: The Unlock iPhone to use accessories when charging prompt is usually triggered when the iPhone thinks that there’s also a data connection and not only power transfer involved. Avoid using USB hubs, or any other middle-man!
