https://www.aboveavalon.com/notes/2018/2/28/the-iphones-turning-point To summarize the piece: The author makes the argument that Apple reluctantly launched 4.7" and 5.5" devices in 2014 after it was clear large smartphones were the future. The iPhone 6 series remains the best selling iPhone in Apple's history. Initially, the sales performance of iPad was extremely impressive. As a result, Apple executives believed tablets were the next big thing. In an effort to win the tablet segment and to follow their vision of tablet computing, Apple launched the iPad mini to defend against Android in the sub-$500 bracket. Eventually, it became clear consumers preferred large smartphones and tablet sales fell dramatically (especially iPad mini) once Apple's iPhone 6 and 6 Plus became available on the market. The author of Above Avalon has traditionally provided good, evidence based arguments. With the trend towards large smartphones and tablets, it's clear the iPad mini is EOL. This article provides a good hypothesis on why iPad mini was alive from 2012 - 2015.
