Despite a wide range of smartphone options available to consumers, Apple remains the largest market shareholder in the U.S. According to a report from Oberlo, Apple now holds more than 55 percent of the smartphone market in the U.S. This means more than half of smartphones sold in the U.S. are Apple hardware. 

This is followed by Samsung, which has seen its market share grow to just over 29 percent, but is still well below Apple. Between the two companies, they control more than 85 percent of the U.S. smartphone market, or the equivalent of 8 out of 10 Americans. 

Samsung has managed to close the gap between itself and Apple. In 2011, Samsung’s market share was 9.12 percent, while Apple held 54 percent. Samsung saw its biggest market share growth between 2011 and 2014, where it grew from 9 percent to 25 percent. 

Coming in a distant third of the total U.S. market share today is Motorola, which has seen its market share fall to 4.9 percent, followed by Google at 2.17 and LG at 1.82 percent. 

Cell phone purchases are on the decline in recent years, as users hold onto their devices longer. According to International Data Corp, worldwide smartphone shipments declined 18.3 percent year over year to 300 units in the fourth quarter of 2022. This marks the largest-ever decline in a single quarter.

"We continue to witness consumer demand dwindle as refresh rates climb past 40 months in most major markets," said Anthony Scarsella, research director with IDC's Worldwide Quarterly Mobile Phone Tracker. 

"With 2022 declining more than 11 percent for the year, 2023 is set up to be a year of caution as vendors will rethink their portfolio of devices while channels will think twice before taking on excess inventory. However, on a positive note, consumers may find even more generous trade-in offers and promotions continuing well into 2023 as the market will think of new methods to drive upgrades and sell more devices, specifically high-end models," Scarsella said.
