How much time, on average, do you think that people spend on their smartphone, and how does this compare to other countries? I think that the average person spends about one and a half to two hours on their smart phone every day. This may sound like a lot, but when you think about using it in the morning, lunch, afternoon, and when you get home for the day it is easy to end up spending that much time on your phone in a day. I think that other countries use their phones less than the average American. This is what I think that average time a person spends on their phone.
