In its most recent earnings release, Apple (NASDAQ:AAPL) for the first time gave an official disclosure regarding just how big its global installed base of iPhones is: over 900 million. That figure was up 75 million over the past 12 months, which when compared to the over 200 million iPhones that Apple likely sold in 2018, confirms that the majority of unit sales are expectedly upgrades. The Mac maker points to that large and growing installed base as the underlying driver of its services business.
The U.S. could represent approximately one-fifth of that worldwide installed base.
Apple is still growing U.S. iPhone users
Consumer Intelligence Research Partners (CIRP) has released estimates today regarding the U.S. iPhone installed base, pegging domestic users at 189 million. That would represent an addition of just 4 million U.S. iPhone users in the fourth quarter. CIRP's installed base estimate would account for 21% of Apple's official 900 million figure.
