How do I fix "This accessory uses too much power" error on my iPhone 15 Pro Max?

Hello,

I have an iPhone 15 Pro Max for more than a year now and every once in a while it gives me hard time charging it.

A few months ago it showed liquid detected message although there were no liquid nor humidity and it worked again next morning.

Now and after the upgrade to latest iOS (mainstream version not beta), it showed a new message, “This accessory uses too much power” it kept doing so every 1 or 2% while charging so I disconnected it and today it refused to charge at all, using the same block and cable!

I usually use my Apple’s block along with an Anker certified 1.8 M cable, I replaced the Anker cable with Apple’s original and the phone started to charge, which looks like a faulty USB C cable, no dear, the same cable is charging my iPad Pro now without any problems.

I have Apple’s original block, Anker’s cube power port III 20w block with 2 cables, Apple’s original and Anker’s 1.8 M certified cable.

No matter which 2 components of the above you will use, eventually they both will stop charging the phone and cause an error message. If you switch the block or the cable, the phone starts charging again. In a few weeks, If I go back to my previous block and cable, they will work again!!

This looks to me like a software issue and not hardware related issue.

I have been an Apple users since generation 1 back in 2007 and I have not regretted any model I got as I regretted replacing my 14 Pro Max with my current 15 Pro Max, the 15 has endless issues with battery performance and charging, unfortunately.
