The larger the phone, the more screen time a user tends to clock. That's what a study published this week suggests. The study comes from the folks at AppOptix and consists of data from 4,000 users surveyed over the entirety of the year 2017. There, they've shown that phones with displays less then 4.6-inches use their devices FAR less than those with displays 5.5-inches or larger. Your big fat phone is making you a phone zombie!
