iPhone 6 Plus with 5.5 inches display is attractive nowadays, but the 4.7-inch size of iPhone 6 is the most popular that Apple focuses on now, according to a survey.

The CIRP, which mainly concentrate on doing survey for customer, said that sales volume of iPhone 6 accounts for 68% of total iPhone sales, and the iPhone 6 Plus is just 23% to 24%. The sales volume of iPhone 6 and iPhone 6 Plus account for 91% of total sales.

An Analyst said that even though the sales of iPhone 6 better than iPhone 6 Plus, there is nothing can explain that customers are in the demand for iPhone 6 Plus. What’s more, the iPhone 6 Plus is still in short supply.

According to the survey, the memory space that most of users need is 48GB, that’s why Apple gives up to produce the storage space of 32GB, and there are only 16GB, 64GB and 128GB three choices for users in iPhone 6 Plus.

The investors prefer users choose the 64GB and 128GB versions of iPhone, which contribute to provide the profit margin of Apple. Because of the positive results the CIRP shows, UBS still supports bullish Apple Shares and tries to target as $125 in 12 months.
