I agree that battery replacement program had effect on sales. But the stability and responsiveness of iOS 12 on older devices had it as well. I'm surprised that Tim Cook did not mention that. I only hope that they won't jump to some crazy conclusions based on those observations...
And personally I believe that apart from higher prices of phones, also insanely growing prices of service (for example fixing phones with crashed screens) contribute to this year's sales failure - it is just more and more risky to go with the iPhone, as its maintenance costs are potentially huge.
