According to a latest survey by Illinois-based Motorola Mobility and Germany-based customer care solution firm B2X, one in six Americans would forfeit friends for a week before their smartphone.
While 74 percent would keep their smartphones within reach throughout the entire day, 60 percent would prefer sleeping with their phones - and this figure jumps to 84 percent for youth aged 18-29.
"Americans are addicted to their smartphones," the survey said that interviewed 518 people.
When asked if offered $100 (Rs.5900) to go without their phone for a day, 40 percent of people said that would be difficult or impossible, according to media reports.
Nearly 53 percent people would keep their phone sound on even while they sleep, the findings showed.
