iPhone had its best quarter ever.

Apple had a great first quarter, but iPhone sales were the standout. The company reports that its signature device posted its best quarter ever, thanks in part to surging sales in regions like China and India.

“iPhone had its best quarter ever, setting record highs across all regions, driven by unprecedented demand,” CEO Tim Cook said during the company’s earnings call Thursday. According to Apple’s earnings report, 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 said there has been a significant surge in sales in China. “This was led by iPhone, where we set an all-time sales record,” Cook said, calling it “the best iPhone quarter in Greater China history.” Cook said enthusiasm for the iPhone 17, which was announced last September, has led to a surge in sales. The new model has proven to be much more popular than the company’s previous iPhones.

According to Apple’s earnings report, overall sales in the Greater China region jumped to $25.5 billion from $18.5 billion a year earlier. Cook noted that, overall, the company has performed quite well in the region. “During this quarter, traffic to our stores in China increased significantly by double digits year-over-year,” he said.

Cook also highlighted India as another region where iPhone and other products are sold. “We set a quarterly sales record during the December quarter,” Cook said. It noted that records were set for “all-time revenue records for iPhone, Mac and iPad (sales) and services.” Cook called it a “great quarter” in the country, which is “the world’s second-largest smartphone market and fourth-largest PC market.”

Excluding the iPhone, Apple’s overall sales surged in all regions, the company’s earnings report said. For example, sales in the Americas increased to $58.5 billion from $52.6 billion a year ago, while in Europe they increased from $33.8 billion to $38.1 billion.
