Jordan Crook, reporting for TechCrunch:
For the first time in its history, the iPhone is experiencing a drop in sales.
In 2015 at this same time, Apple sold 61 million units of the iPhone. This year, for the period ending March, Apple only sold 51.2 million units, representing a 16 percent YOY drop.
This is to be expected. As smartphone hardware matures, there’s less of an incentive to upgrade to the latest model — all of the compelling features have already been built. Folks like you and I might upgrade every year or two, but I expect it will become increasingly common for average users to continue using their handset until it doesn’t work anymore.
