Apple doesn’t share iPhone unit sales any longer. But a new study from research firm Gartner is providing the details. And it’s ugly.
During the fourth quarter of 2018, global iPhone sales hit 64.5 million units, earning Apple 15.8% market share during the period. That was down from 73.2 million unit sales and 17.9% market share during the fourth quarter of 2017, according to Gartner. Apple’s drop was the biggest decline of any major smartphone maker during the period.
