Bank of America's new study found 47 percent of mobile phone users in the U.S. said they wouldn't last a day without their smartphone.
Many of the participants considered their devices to be more important than coffee and television, and some users said they'd rather give up alcohol or chocolate than their phones, according to TG Daily.
The study was conducted by Braun Research and is based on telephone surveys of 1,000 smartphone users with Bank of America accounts. The survey included major target markets, such as California, Florida, Atlanta, Boston, Charlotte, New York, Chicago and Texas.
The survey also found smartphones were more important than toothbrushes or deodorant for Millennials, USA Today reported.
When ranked by level of importance to people's daily lives, smartphones were only ranked below hygiene and the Internet. 91 percent of participants said they care about their mobile devices as much as they care about their car and deodorant.
The survey also brought up the use of mobile banking apps for transactions, with 58 percent of participants having used mobile check deposit, and 38 percent using it often, TG Daily reported.
"Mobile check deposit has been one of the fastest growing digital services we offer," said Marc Warshawsky, senior vice president and mobile solutions executive at Bank of America. "Customers appreciate the convenience of being able to complete their deposit anytime, anywhere and are depositing an average of 170 thousand checks via mobile device every day."
76 percent of the participants found their smartphones to be more important than television, and 60 percent of them found their mobile devices to be more important than coffee, TG Daily reported. The ranking of the devices over toothbrushes and deodorant was most common among younger smartphone users.
"When asked what they would give up to regain access to their mobile phone, nearly four in five (79 percent) of respondents would be willing to give up alcohol or chocolate," the report stated.
