Apple has seen demand for its iPhone reach new heights with sales growth in China outpacing all other regions.

Overall, sales of Apple products grew 17% to $111bn (£81bn) in the first three months of the year, compared to the same quarter a year ago, the company said in financial results released Thursday. Sales in China were up by 28% compared to a year ago.

Tim Cook, Apple's outgoing chief executive, said that recent demand for the iPhone had been "extraordinary", making the iPhone 17 the "most popular launch in [Apple's] history."

Despite continued iPhone success, sales of Apple's other products, including the Mac computer and wearable devices like the Apple Watch, remained relatively flat.

However, Cook told financial analysts on a call to discuss the company's performance that the new Macbook Neo was seeing "off the charts" demand. He said the quarter set a record for new Mac buyers thanks to the Neo, which is sold at a significantly lower price than other Mac laptop computers.
