iPhone revenue as share of Apple's total revenue 2009-2024, by quarter

iPhone sales made up approximately 50.6 percent of Apple’s total revenue in the second quarter of the company’s fiscal year 2024. iPhone sales usually contribute to half or more than half of Apple’s overall sales revenue. Apple’s other businesses such as the Apple Watch and the iTunes Store have been bringing in growing shares of revenues, from around five percent in 2017 to a combined almost 30 percent in the second quarter of FY 2024.

Apple is the second largest smartphone vendor

As Apple’s most successful product, the iPhone is one of the most heavyweight players in the smartphone market, with dozens of millions of iPhones being shipped every quarter. Indeed, when it comes to smartphone vendor share, Apple is the second largest smartphone vendor in the world, after Samsung. iPhone runs the iOS system, which is Apple’s inhouse operating system. Most other products on the market run the Android system developed by Google. iOS occupies around a quarter of the overall mobile operating system market, Android the rest.

The differences between iOS and Android

iOS is a closed system while Android is more open, which means that users can better customize their phones using the Android system. Because of its open nature, Android is also an easier target for hackers, whereas iOS is considered safer as Apple does not release its source code to developers and users. Both operating systems get regularly updated – Android 13 is Android’s 13th major release, and iOS 17 is the 17th major iOS release. Due to the great many models of Android phone devices, the Android versions are more fragmented than iOS, with older versions like Marshmallow and Lollipop still running on a big number of devices, whereas iOS 17, released in 2023, runs on around 66 percent of all Apple devices when looking at iOS version share.
