Apple's iPhone revenue for the quarter is marginally below predictions because of supply constraints, but sales will instead manifest in what Tim Cook is calling the best holiday quarter ever.

In Apple's latest quarterly earnings report, Wall Street analysts had expected the company to report iPhone sales of $50.19 billion. Instead, the company says it made $49.03 billion.

Ignoring that analysts who make these predictions having no clue what's going on inside Apple at any given moment, Tim Cook isn't concerned about it.

Tim Cook accounted for the shortfall by saying that "for Q4 several models [were] supply constrained." He added that "currently we're supply-constrained on several models of the iPhone 17."

That follows higher than expected demand for the iPhone 17 range, particularly the iPhone 17 Pro Max. That model went on backorder almost immediately after going on sale.

At time of writing, the iPhone 17 Pro Max is available in-store at many locations. However, typical delivery from the online store is still between two and three weeks.

Tim Cook has also said that he expects sales in China to expand during the next quarter. That follows reports that the iPhone Air sold out in minutes in the country — and the whole iPhone 17 range broke records.
