I have an iphone 8+. I bought a pair of braided cords off amazon not long after I got my phone and they have been great. I can't find the exact cords I bought in my purchase history, but these look the most like what I have.

I bought the 6 foot cord for a number of reasons. It's been more helpful than a hinder having that much cord.

One cord stays home, but the other gets used (and abused) out and about. In two years, I have never had an issue with the end fraying like you show, or any connection issues. One thing the braided cord has over the factory cord is the plug end for the phone is a slightly smaller diameter so it works better with my Otter Box case.
