University of Maryland junior is dependent on cell phone, doesn't think his use is healthy

According to a pew report, 46 percent of smartphones owners "couldn't live without their devices."
University of Maryland junior Karl Griner agrees with that sentiment.

Americans have taken advantage of the unlimited information at their fingertips.

Many Americans (30 percent) use their phones to take classes, and even more (44 percent) use their devices to look up real estate listings.

Griner has felt the pull himself.

"I would say its probably a bad thing to be so dependent on my phone," Griner said. "I don't really know why, but I feel like its unhealthy."

He added he checks his phone about every 15 minutes.

Griner isn't alone, though.

For many people, smartphone use has become a sort of addiction.

"Even if I don't think I have something — a message, or notification, I check to see if there is," Griner said. "I don't want to be missing out on something."
