Lookout's analysis, from more than 15 million users, found that demographics and behavior are the largest factors influencing phone loss. Over the course of 2011, Lookout located 9 million lost smartphones, which equals one phone every 3.5 seconds. In total, Lookout found that U.S. consumers lose their phone about once a year. If unrecovered, that could cost every smartphone owner more than $250 a year each.
"Each day, $7 million worth of phones are lost by Lookout users alone, and if unrecovered, it would take a significant toll not only on our wallets, but on our psyche too," said Kevin Mahaffey, co-founder and CTO Lookout. "Safeguarding your smartphone starts with protecting it from the number one risk you face - losing it."
What are the odds? People in some U.S. cities have a higher chance of losing their phone: Philadelphia residents lose their phone two times more than New York City dwellers, while San Franciscans and New Yorkers lose their phones three times more than Chicagoans.
