All these rumors have dampened excitement for Apple’s current model, the iPhone 7, Cook said earlier this year. And unconfirmed reports of manufacturing delays have added an extra layer of uncertainty to the mix.

Nonetheless, analysts have speculated that features like voice compatibility with the new HomePod speaker could make Apple’s ecosystem more useful for consumers, boosting Apple’s ability to sell services like Apple Music.

“If you look at Services, we came in at $7.3 billion, which was up 22 percent year-on-year, really great quarter,” Cook told CNBC. “And we have now achieved our goal of being the size of a Fortune 100 company earlier than we thought.”

Still, the company is not without challenges, especially in China, where sales fell 10 percent year-over-year this quarter and 14 percent year-over-year last quarter. Local competitors such as Huawei and Xiaomi have pressured Apple’s market share, while Apple has added executives and bent to accommodate regulators in Beijing.

Cook told CNBC that the company still feels “great” about third quarter performance in China, accounting for currency.
