17.4 million device activations occurred on December 25.
More tablets and smartphones were activated on Christmas than ever before, according to data from analytics firm Flurry.
Device activations increased from a daily December average of 4 million to 17.4 million on Christmas day, representing an increase of 332 percent. It's also more than double the 6.8 million devices activated on Christmas last year, which was the previous single-day record holder.
More tablets were activated on Christmas this year than handsets, with the iPad accounting for a considerable proportion of the category. The Kindle Fire HD 7-inch tablet, meanwhile, experienced its strongest showing ever.
App downloads also increased by more than double their daily December average on Christmas. On December 25, device owners downloaded 20 million apps per hour, Flurry said.
"Over the next week, up through New Year’s Day, app download rates will remain significantly elevated. Flurry anticipates downloads to surpass more than 1.5 billion, and have a shot at breaking through the 2-billion download barrier for the first time ever. We look forward to accelerated growth in 2013, and continued success for developers."
