YouGov's survey shows that the proportion of Brits using a smartphone has risen by just two per cent in the last six months.
Analysts have, therefore, called on manufacturers and networks to do a better job of explaining the benefits of smartphone ownership.
This comes after the poll found that just 14 per cent of over-55s are smartphone users.
"The challenge for the industry is to better explain the benefits of smartphone ownership to current rejecters, notably older age groups and women," commented YouGov's Russell Feldman.
However, Ovum analyst Tony Cripps said: "Over time a higher and higher proportion of phones in use are going to naturally be smartphones as prices come down.
"In the long run the situation won't remain the same simply because technology always percolates down."
Elsewhere, new research has suggested that 35 per cent of US adults now own a smartphone. Pew Internet and American Life Project observed that smartphones are gaining ground in the US market.
This is because, the firm explained, wireless providers are pushing smartphones over cheaper, simpler "feature" phones.
