On average, Americans spend roughly four hours and 37 minutes on their phones per day, which translates to one whole day per week, six days per month, or about 70 days per year.
A person's screen time can have significant effects on their life. For instance, with a national life expectancy of 78.4 years, excessive screen time can lead to losing several years to checking notifications and constant doomscrolling.
For example, with an iPhone screen time average of six hours and 16 minutes, using a screentime calculator revealed that this rate could cost around 14.25 years of life, not accounting for a fully-online job.
At my current rate, those six hours a day will cost me 14.25 years of my life.
