A report released Thursday says 4.5 million smartphones were lost or stolen in the U.S. last year, up from 2.8 million in 2012.
Thefts were largely responsible for the increase in devices that were permanently separated from their owners, according to Consumer Reports’ annual State of the Net Survey. The organization, which tests products, said device thefts nearly doubled from 1.6 million in 2012 to 3.1 million in 2013.
The number of lost devices increased from 1.2 million in 2012 to 1.4 million in 2013. More than 3,100 adults in the U.S. participated in the Consumer Reports survey that was used to calculate the figures.
“Our survey revealed that the number of lost and stolen smartphones is on the rise, and too many smartphone users are needlessly imperiling their personal data by not taking basic security measures,” said Glenn Derene, Consumer Reports’ electronics editor.
