Apple's iPhone and iPod Touch models account for as much as one third of worldwide mobile data traffic.
A recent report from mobile advertising specialist Admob said that the Apple handsets accounted for 32 per cent of its worldwide mobile data requests during October, a rise of seven per cent on the previous month.
In terms of smartphone web traffic, the iPhone alone accounted for a whopping 50 per cent of traffic.
Second to Apple on both lists was Nokia, which claimed 19.6 per cent of data requests and 24 per cent of smartphone web traffic. Samsung was third and Research In Motion seventh.
The iPhone and iPod were far more dominant in the UK markets, where Apple made up 60.5 per cent of handset data requests and 74 per cent of smartphone web traffic requests during October.
Researchers noted that Nokia maintained a strong position in emerging markets such as India and Indonesia, where it has a sizeable lead over other smartphone vendors.
