Unused smartphone applications will cost UK mobile phone owners £747m in 2010.
A study of 1,476 UK phone owners by discount website MyVoucherCodes showed 79% of smartphone owners were "highly unlikely" to use a paid-for phone application or game more than once, wasting £747m on applications disregarded after the first download by the end of this year.
Mark Pearson, managing director at MyVoucherCodes, said, "Mobile applications have become the mobile equivalent of impulse buys. Their relatively low cost means that, despite the fact that there are millions to choose from, only a certain percentage will ever be used beyond the initial download, as the novelty soon wears off.
"As cool as having an application that turns your handset into a light sabre is, think about whether you are going to be using it beyond the initial download - if not, it is probably money that has not been particularly well spent."
The study surveyed UK mobile owners across mobile networks including Orange, Vodafone, O2, 3 and T Mobile. Of those polled, 19% download at least one application every week.
