Mobile shopping enjoyed a 187 per cent rise during December 2011 compared to the same month in 2010, according to IBM.
The report found that sales from mobile devices accounted for 12.9 per cent of all purchases in December 2011, compared to 4.5 per cent in the same month the previous year.
It was also revealed that 15 per cent of retailers' website traffic came from a mobile device, up from 5.6 per cent in December 2010, which is a 169 per cent increase.
Andrew Jackson-Proues, enterprise marketing manager leader for UK and Ireland at IBM, said: "This Christmas shopping season has been characterised by consumers looking for deals and increasingly using their mobiles to shop online."
Tablet devices also continued to drive more retail purchases than any other device as they enjoyed conversion rates of 6.1 per cent compared to 3.8 per cent from smartphones.
A recent study by Marin Software found that click-through rates on online ads on tablets were 38 per cent higher than on desktop computers during the final quarter of 2011.
