The company planed to provide updates on both the iPhone base and overall device base on a "periodic basis," Maestri added. He didn't break down the base by model, but the company did confirm that the iPhone XR was the most popular, followed by the XS Max and the regular XS.
The figure isn't available purely out of generosity, of course. This helps emphasize that the iPhone base is still growing at a substantial rate, and helps it show investors how many customers are subscribing to services (there are more than 360 million paid customers across services, if you're wondering). In essence, it's trying to tweak the thinking of investors used to paying attention to iPhone sales on a quarter-by-quarter basis.
Not that the company is content to simply tout different figures. In the call, Tim Cook noted that Apple was looking at pricing iPhones according to local currencies in China and other countries, rather than pegging them to the US price. That would bring prices closer to where they were a year earlier -- in other words, they're price cuts. While changes in pricing weren't that dramatic in the US, they were "amplified" by foreign exchange rates. Apple wants to keep iPhone sales healthy, and it's willing to absorb some of the currency changes if it helps move units.
