If you wonder why you never have any time to do anything, you might want to look at the culprit that is causing the time suck: Your smartphone. A new study asked 2,000 Millennial and Baby Boomer smartphone users to go into their phone settings and record exactly how much screen time they've spent on their top apps. The survey found that both generations share similarities when it comes to how much time they spend on their smartphones.

The average American spends 5.4 hours a day on their phone. Millennials spend slightly more time on their phones (5.7 hours) compared to baby boomers (5 hours) on average. However, 13% of millennial and 5% of boomers say that they spend over 12 hours every day on their phones.

Overall, social media takes up the bulk of smartphone screen time. Americans spend an average of just over an hour (64.5) minutes a day on Facebook and 48 minutes on Instagram.

One-out-of-three thought their screen time would be less than it actually is, and underestimate how much time they spend on their phone. Yet, two out of three users do not plan on cutting back on phone usage. Many are in denial. Over four-out-of-five (82%) people think their personal usage is below that national average.
