Other Apple products like the iPad and Mac brought in a sizable portion of the quarterly revenue, but compared to the previous holiday quarter those products dropped off. Apple's wireless headphones, its new speaker, the HomePod, and the Apple Watch together with other products saw revenue growth, up more than 30 percent from this time past year - though the HomePod wasn't available then. Apple said it will also raise its quarterly dividend by 16% to 73 cents per share in its largest jump in six years.
Total iPhone sales during the quarter, which account for more than 60 percent of Apple's total revenue, rose by 14 percent from past year.
Luca Maestri, the company's CFO, said the business performed "extremely well" during the March quarter, as it grew earnings per share by 30% and generated more than $15bn in operating cash flow.
"We're thrilled to report our best March quarter ever, with strong revenue growth in iPhone, Services and Wearables", Apple chief executive Tim Cook said. The previous best third quarter was 2015, which saw $49.6 billion in revenue. However, Apple beat its second quarter performance from a year ago, when it has shipped 50.7 million iPhones. Revenue for the company topped estimates at $61.1 billion, and earnings per share also came in above expectations at $2.72 a share.
