iPhone 12 remains the most popular model, iPhone 12 Pro sales strong too: Apple CEO Tim Cook

"iPhone 12 is the most popular, but we did see very strong sales of the Pro models as well.

When asked about how the iPhone cycle has changed compared to previous cycles, the Apple CEO has said the company "doesn't predict going forward, other than for our own internal use."
