Android owners in the UK transfer 78% of their internet content using W-Fi, according to new smartphone analytics from Nielsen.

Nielsen says that mobile data “offloading” – ie using Wi-Fi instead of a phone’s 3G connection – among Android users follows the working day’s rhythm, with the practice increasing each hour after 5pm until it reaches a peak between 11pm and midnight, when 90% of data transferred is via Wi-Fi.

3G data, meanwhile, peaks between 8am and 9am, just before the working day starts, and again at lunchtime and during the evening commute.

Nielsen European managing director for digital David Gosen explained, “Wi-Fi is on average three-and-a-half times more dominant than 3G when it comes to delivering mobile internet data services. It peaks around midnight as users gravitate towards social networks, driven by their desire to stay connected through all waking hours.”
