So, Apple sold fewer iPhones in Q4 2017 than the year before and that's while having both the iPhone 8 and iPhone X in steady supply. The dip in sales is alarming to some because it is the first time in the iPhone's history that it's decreased year over year. There's various reasons that analysts are trying to determine as the cause. Higher price of the iPhone X, confusion or indecision in choosing between iPhone 8 Plus and iPhone X, uncertainty about the lack of of Touch ID on the X, the list goes on.
Despite this, Apple still had record earnings and now Strategy Analytics is telling us the entire smartphone industry has taken a 9 per cent decline in 2017. This is mostly attributed to a 16 percent decline in demand from China, the biggest smartphone market in the world.
