The research firm said that adults will spend one hour 59 minutes a day on their smartphone in 2017, compared to one hour 58 minutes for desktop and laptops, with the rise of mobile use attributed largely to digital video viewing.
Videos, particularly on social media platforms, as well as the popularity of messaging apps were defined as “the key drivers behind the mobile uptick” with mobile use expected to rise in the coming years as computer use continues to fall.
Broadcasters are increasingly experimenting with premium content for the smallest screens, with Canal+ launching its Studio+ service earlier this year as one example.
Daily time spent on smartphones in the UK will reach two, hours 14 minutes by 2019, compared to one hour 54 minutes for desktops and laptops,according to the research.
Overall, the forecast shows that this year UK adults will spend two hours, 45 minutes per day with mobile-only devicesm, including tablets, and will watch an average of 31 minutes per day of digital video on these devices – up 13.5% from 2016.
Adults in the UK are also tipped to spend one hour each day on social networks this year, with 34 minutes of that time spent accessing these platforms via a smartphone.
In terms of overall media consumption, adults in the UK are expected to spend an average of nine hours 31 minutes per day with “major media” in 2017, up 0.5% from last year.
eMarketer predicts that digital media, including mobile, will account for 49.6% of all media time this year, while TV will account for a 31.7% share – down 2.3% compared to 2016.
“Mobile use is increasingly coming to mean smartphone use in the UK, so it’s no surprise to see the time spent forecast tilting ever-more in that direction,” said eMarketer senior analyst Bill Fisher.
“The trend within this trend is the growth in social media and video time. More than any other media on any other device, UK adults are migrating their social media and video habits to smartphones.”
