Report: Apple's iPhone 6s is four times more popular than the iPhone 6s Plus
Although it's definitely not surprising to see that the iPhone 6s is selling much better compared to its larger and pricier sibling, it's worth noting that the second-coming of the Apple phablet appears to be doing much better compared to the original version in terms of first-week sales. Last year, after one week of availability, the iPhone 6 Plus accounted for about 0.3% of all active iPhones, down significantly compared to the 2.4% share of the iPhone 6.
At this point, it should be noted that while the iPhone 6s and 6s Plus adoption rates have dropped compared to those of the iPhone 6 and iPhone 6 Plus, this doesn't mean that fewer units have been shipped. The reason for the discrepancy in numbers between the two iPhone generations comes from the fact that there are simply much more iPhones currently out there compared to a year ago, following the phenomenal sales success of the iPhone 6 series throughout the last four quarters.
If you're wondering which is the most popular iPhone model at the moment, then the answer shouldn't surprise you. According to data from Localystics, the iPhone 6 accounts for a third of all active iPhones, followed by the iPhone 5s with a share of 23.2% and the iPhone 5 with a share of 11.2%. Again, note that these shares do not come from brute sales numbers. Instead, these percentages represent the ratio of a certain iPhone model in the total pool of active iPhones.
