According to BlueFin Research, Apple will discontinue both the iPhone X and iPhone SE this fall.
The iPhone X and iPhone SE will be discontinued this year due to the 'pent-up demand' for this year's models, the iPhone 9, iPhone 11 and iPhone 11 Plus, how they are called now. During the latter two quarters of 2018, Apple is expected to manufacture 91 million units of the new 2018 iPhones. During the first two quarters of 2019, the company is expected to manufacture 92 million units.
For the fall, the analysts model Apple making 28 million units of the iPhone 9, and 11 and 11 Plus in Q3, up from a prior estimate of 24 million units. They expect another 63 million units in Q4, 46 million units in Q1 of next year, and 46 million units in Q2. All those numbers are higher than they were previously.
The iPhone 8 is expected to stay available as a lower-end and cheaper model, while the iPhone X and iPhone SE will probably be discontinued. The iPhone X because the 2018 iPhone models will probably be cheaper than the iPhone X, and the iPhone SE because the smartphone is 2.5 years old this fall (it was released in March of 2016).
The iPhone 11 Plus should satisfy those unhappy with the iPhone X due to size concerns, while the iPhone 9 device should satisfy more budget-conscious buyers and the aforementioned extension of the iPhone 8 model builds will round out a fairly extensive line-up. We continue to hear that upgrade activity over the past.
The iPhone X would presumably be discontinued in Q3 of this year, and the cheaper “iPhone SE” would also go away.
