A nationally representative survey (Mobile User Survey 2010 by Enders Analysis) of 1,000 UK adults were surveyed by telephone over the period 26-28 March 2010, revealing very interesting results.

UK handset sales are likely to continue to rise, with intention to replace in the next 12 months rising from 32% in 2009 to 35% in 2010. Nokia remains the UK’s leading handset brand, but its share fell to 40% from 44% last year, and Apple increased its market share in 2010 to 6%.

In terms of intended next handset manufacturer brand, Nokia held growth, but again the main gainers were the iPhone and Blackberry, with the iPhone’s share moving to 11% from 4% last year, both gaining share amongst O2 customers and the new operators to offer the handset now the O2 exclusivity has ended

Smartphone data usage is consistently high across gender, age and socio-economic group, with little of the usage drop-off seen from traditional handsets and non-smartphone touchscreens. Demographic trends show overall data usage ends up being pretty flat across the 16 to 34 age range.

Unsurprisingly smartphones are used more for data services than compact models, but more surprisingly:

–Android and similar device owners use data even more than iPhone owners, although they do not download apps as much

–Nokia’s flagship N-Series and E-Series handsets have far lower data usage than other smartphones, and their other S60 handsets have lower usage still (albeit at least better than other non-smartphone touchscreens)

– Handsets that have touchscreens but do not otherwise qualify as smartphones (semi-smartphones) still have twice the data usage of traditional form factors
