The other thing about AppleCare is that it covers the headphones and charging cables as well. For some reason my Apple branded lightning cable seem to fail somewhat regularly. It's always the same pin that turns black and stops working. I run with my iPhone and sometimes the headphones go bad, although that seemed to happen more often with the older round style than with the newer EarPods. I've replaced quite a few of those under app,e care as well. I think the lightning cables run about $20, so if I replace two of them over the course of the two year warranty, the effective cost of the warranty is only $50. It's definitely not for everyone, but I find the peace of mind I get from having apple care to be well worth the cost.
I still have original lightning cables from my iPhone 5 purchase. If you go through wires that much then you're mistreating them. They don't just fail regularly on their own if you handle them properly.
