Apple had a great Q1, although iPhone sales were the real standout. The company reported that its signature device had its best quarter yet, thanks partially to a surge in sales in regions like China and India.

“iPhone had its best quarter driven by unprecedented demand, with all-time records in every geography,” said CEO Tim Cook during the company’s earnings call Thursday. by Apple income report showed the company sold $85 billion worth of iPhones in the first quarter, up from $69 billion in the same period last year.

During the Q&A portion of the call, Cook revealed that China has seen a huge surge in sales. “It’s driven by iPhone, where we set an all-time revenue record,” Cook said, noting that it was “the best iPhone quarter in the history of Greater China.” Cook said the sales explosion was due to enthusiasm for the iPhone 17, which is announced in September. The new model has proven to be very popular than the company’s previous iPhone.

Apple’s earnings report showed that its total sales in the Greater China region jumped from $18.5 billion in the previous year’s quarter to $25.5 billion. Cook noted that, overall, the company is doing well in the region. “I will tell you that in the quarter, the traffic in our stores in China grew by strong double digits year over year,” he said.

Cook also highlighted India as another region where iPhones—as well as other products—seem to be flying off the shelves. “We set a quarterly revenue record in the December quarter,” Cook said, noting that records were set for “iPhone and Mac and iPad (sales) and an all-time revenue record in services.” Cook called it “an incredible quarter” in a country he noted is “the second largest smartphone market in the world and the fourth largest PC market.”

Except for the iPhone, Apple’s overall sales jumped in every geographic region, its earnings report showed. In America, for example, sales went from $52.6 billion last year to $58.5 billion, while in Europe, it increased from $33.8 billion to $38.1 billion.
