According to an Apple Insider report, Apple CEO Tim Cook during the fiscal Q2 2021 earnings call, revealed that the iPhone 12 is the most popular device in the series, and even the iPhone 12 Pro Max is seeing very strong sales. Allegedly, Cook didn't mention the iPhone 12 mini during the call, which suggests that the handset hasn't done well in terms of sales. To recall, Apple reported a whopping $89.6 billion dollars in revenue for fiscal Q2 2021, ending March 27.
