iPhone sales heat up while iPad slows down

Apple today released its results for its fiscal fourth quarter 2015, which is the three-month period ended Septmber 26, 2015.

It's notable that the period does not include much in the way of iPhone 6S and 6S Plus sales; the devices were released on September 26. Even so, Apple's phone sales leapt over 22 percent year-over-year, to 48 million for the quarter. The iPad, however, slowed down -- sales were down over 19 percent year-on-year, to 9.8 million.

It's also worth noting that the company hasn't begun to break out the sales of Apple Watch for investors.

Though they grew in every region, Apple's quarterly revenues in China almost doubled year-on-year -- in line with news that the country's mobile game playing population has ballooned during 2015. Of course, while there's an ever-increasing number of mobile players around the globe, the pie is not sliced evenly, the data shows.

Overall, Apple is in rude health: revenues for the quarter were $51.5 billion, with profits of $11.1 billion. In a statement, CEO Tim Cook called the company's fiscal 2015 its "most successful year ever," with revenues of $234 billion.
