CIRP conducted a survey of 500 people in the United States who bought iPhone, iPad or Mac this year in the period between January and March.
The survey shows that 23 percent of iPhone purchased is iPhone 8 and 21 percent purchased is iPhone 8 Plus. Meanwhile, the contribution of iPhone X declined from 20 percent in the last quarter to 16 percent.
The CIRP survey shows that sales of the iPhone X have declined since last quarter, while the iPhone 8 and iPhone 8 Plus have gone up.
Considering the respondents of this survey only 500 people, the findings can not fully describe the state of the market.
Since the iPhone 6 was launched in 2014, Apple has not changed much of the iPhone's design except the iPhone X, which has a completely different design. However, the phone also has a more expensive price than the iPhone 8 and iPhone 8 Plus.
Indeed, the iPhone X has some special features, such as Face ID, thin bezel design, OLED display, wireless battery charging and also Animoji.
The declining sales of iPhone X indicate that consumers are not interested in the premium features of the phone or the price of the iPhone X is considered too expensive.
On February 1st, Apple CEO Tim Cook said that iPhone X was sold at most every week since it was launched in November. However, he discusses global sales, while the CIRP survey only takes into account US sales.
