WhistleOut publisher Joseph Hanlon said that the data he had used to come to this conclusion was "share of voice" reports, "some of the market data we share with our telco partners".
The prices for the new iPhones are $1799 (iPhone XS Max), $1629 (iPhone XS) and $1229 (iPhone XR). The iPhone 8 is available for $979 and the iPhone 8 Plus for $1149. Prices vary depending on storage.
Hanlon said the data, which was provided to iTWire, was a combination of two sets of statistics from the WhistleOut site: clicks on the "Go to site" lead generation button for each phone plan and also the hits on the product description pages in search results tables.
In Australia, 10.13% of the share of voice in 2016 was for old iPhone models; that fell to 7.57% in 2017 and rose sharply to 22.39% this year, indicating a much higher interest in the purchase of the older models.
For new iPhone models, the percentages were 24.46 (2016), 17.27 (2017) and 15.57 (2018), a clear indication of decreasing interest in the new models.
Hanlon also provided stats for Samsung phones; these were 8.16% in 2016, 17.5% in 2017 and 19.31% in 2018, again showing that there was renewed interest in these models this year. This could be tied to the iPhone prices as well.
The US figures showed that in 2016 older iPhone models attracted 25.57% of share of voice reports; this rose to 29.32% in 2017 and went up further to 36.48% in 2018.
For the new iPhone models, the percentages in the US were 31.47 (2016), 15.22 (2017) and 25.71 (2018).
In the US, the Samsung models attracted 22.55% of share of voice reports in 2016, 27.21% in 2017 and 22.7% in 2018.
Hanlon said there more than half a million visits to the WhistleOut iPhone pages in 2018.
