Apple’s share of smartphone ownership increased for the sixth consecutive Piper Jaffray Taking Stock With Teens survey. Of ~6,000 respondents, 82% have an iPhone, the highest percentage we have seen in our survey (up from 78% in Fall-17). The iPhone may have room to move higher with 84% of teens anticipating their next phone to be an iPhone, also the highest ever recorded in our survey (up from 82% in Fall-17). Android was the runner up with 11%, down from the fall. The Apple Watch was the top smartwatch among teens, garnering 15%, with the Samsung Gear next on the list at 2%.
