New research has found that smartphone users now use their devices for web browsing and social media more than phone calls.
Mobile network provider O2 conducted the research, and discovered that smartphone users spend an average of 24 minutes and 49 seconds a day browsing the internet on their devices.
Other popular smartphone activities include checking social media sites (17 mins 29 secs a day), listening to music (15 mins 38 secs) and playing games (14 mins 26 secs).
This compares to 12 minutes and six seconds spent making phone calls, 11 minutes and six seconds checking emails, and 10 minutes 12 seconds sending text messages.
While an average of just three minutes and 28 seconds was spent using the smartphone's camera, a survey of O2 customers found that photography was the most popular feature on a smartphone, with 74 per cent saying they had taken photographs on their phone.
David Johnson, UK general manager of devices for O2, said: "Smartphones are now being used like a digital Swiss Army knife, replacing possessions like watches, cameras, books and even laptops.
"While we're seeing no let-up in the number of calls customers make or the amount of time they spend speaking on their phones, their phone now plays a far greater role in all aspects of their lives."
It should come as no surprise that the smartphone is becoming such an important fixture in our daily lives, but these figures show that mobile should now be one of the biggest factors to consider when devising your online marketing strategy.
