The Iphone 8 and 8 Plus were released towards the later part of September, and the iPhone X was released in early November, which means that the iPhone 8 and 8 Plus had more than a month advantage compared to the iPhone X in terms of sales, but it seems that earlier reports of the iPhone 8 and 8 Plus not selling so well could be true.
According to Business Insider, they point towards data from analytics firm Mixpanel which reveals that the iPhone X’s adoption has managed to outpace that of the iPhone 8 and 8 Plus, despite it being more expensive and released later. In fact as you can see in the chart above, the iPhone X’s adoption has outpaced that of the iPhone 8 and 8 Plus by a pretty huge margin.
That being said, we can’t say for sure if these numbers are accurate. Apple in the past used to release official figures for first weekend/week sales, but the company has stopped doing that in recent times, meaning that many have had to rely on third-party data. However like we said, the data from Mixpanel sort of confirms earlier reports, in which the demand for the iPhone 8 and 8 Plus weren’t as hot as many would have expected.
