This news is completely inaccurate as the 2018 figure of 91% loyalty is from a different company (CIRP) with a different methodology. Only the 2019 figure of 73% is from BankMyCell's own data using their own methodology.
If we stick with CIRP figures for both 2018 and 2019, we discover that iPhone loyalty is actually still at that all-time high of 91%.
But the kicker is that if we DO look at BankMyCell's own data for 2018 and 2019 (as shown in the graph below), it shows that iPhone loyalty has INCREASED 2.7% instead of decreased.
In other words, this whole story is completely bogus with BankMyCell showing two completely different results with the supposed drop only appearing based on a faulty comparison with different survey company results and methodology.
If they had stuck with their own data for 2018 and 2019, the article would be all about how iPhone loyalty had increased since last year.
Completely Crazy.
