It appears that "nomophobia" is rising to new heights in the U.S.

A recent survey by the Bank of America found out that 47 percent of U.S. adults said they wouldn't last a full day without their smartphones. More surprisingly, the survey discovered that a majority consider their smartphone more important than the daily needs in their lives such as coffee and TV.

Four out of five respondents said they would rather give up alcohol or chocolate in order to get their phone back.

The survey also discovered that being constantly connected has become such a part of American lives. Americans' addiction to their smartphones is so strong it ranks below only the Internet and personal hygiene when ranked by importance in Americans' lives.

Nomophobia means a huge fear of losing one's mobile phone. First coined by British researchers in 2008, the word nomophobia is a relatively new word for a relatively new "disease." It's also known as mobile phone addiction

The survey also revealed that 91 percent of those surveyed said their smartphone is as important to them as their car while the same percentage said their smartphone was just as important to them as their deodorant.

Millennials, or persons born from the early 1980s to the early 2000s, were as equally nomophobic about their smartphones. Some 30 percent of millennials also said they'd go back home to get their smartphone, no matter the distance.

Over 120 million smartphones were sold in the U.S. in 2013. Apple's iPhone accounted for 45 percent of this total while Samsung took a 26 percent share.

The survey included 1,000 people older than age 18 with either a checking or savings account and a smartphone. Its margin of error was 3.1 percent.

The Bank of America survey also jibes with one conducted in 2012 by Internet security firm SecurEnvoy which found that 70 percent of women and 61 percent of men worried about losing their smartphones.

The SecurEnvoy survey showed that younger age groups had more people that would feel distressed without their mobile phone. In the 18-24 age group, 77 percent revealed nomophobia. That number fell to 68 percent in the 25-34 age group.
