According to a new analysis from Kantar Worldpanel, the most recent figures for the iPhone 6s and 6s Plus amount to a “solid” performance when compared to Apple’s iPhone track record.

Based on the first full month of sales figures, the latest iPhones are doing pretty well. Though overall market share is down to 33.3 percent from 40.8 percent in 2013 and 41.5 percent in 2014, sales volumes are on par with 2013’s numbers. However, sales volumes are down about 25 percent from 2014’s record-breaking figures.

Kantar said some of the figure shifts can be accounted for by changing market conditions, as the overall market is down about six percent from 2014 and up about 22 percent over 2013.

As a percentage of iOS device sales overall, Kantar said the iPhone 6s represented nearly a quarter of all iPhone sales in the quarter ending October 2015. Though this figure was down a bit from the 33 percent of iPhone sales garnered by the iPhone 6, it was up slightly from the 22 percent share snagged by the iPhone 5s.

Kantar said the iPhone 6s Plus was at 10.8 percent in the same quarter, up a smidge from 10 percent for the iPhone 6 Plus in 2014 and down from 16 percent for the iPhone 5c in 2013.

According to Kantar, the sales figures for iPhones without hardware upgrades tend to gain momentum more slowly than those that have a full redesign. For example, where the iPhone 5s as a percentage of all iPhone sales went from 13 percent in September 2013 to 45 percent in December 2013, the iPhone 6 went from 32 percent in September 2014 to 55 percent in December 2014. Current figures suggest that sales of the iPhone 6s will follow the same gradual increase as the iPhone 5s, Kantar said.

Among consumers, Kantar said the major factors cited as driving iPhone purchases were screen size (52 percent), camera quality (42 percent) and LTE capabilities (31 percent).
