According to a press release on IHS' website on Wednesday, the new iPhone 7 was the best-seller in the fourth quarter alone, followed by iPhone 7 Plus.
"Apple again has demonstrated that its new iPhones integrate enough innovations and new features to drive sales and remain successful in the market. The company is also capable of selling older devices for an extended period of time," the statement added.
The year-old iPhone 6s and 6s Plus were both among the most-shipped models in 2016.
Meanwhile, Samsung Galaxy S7 Edge and S7 ranked fifth and ninth, respectively, outperforming S6 and S6 Edge in terms of sales.
With the recall of the Note 7, S7 and S7 Edge became the best flagships in the premium line-up of Samsung.
