A third of U.K. adults check their mobile devices in the middle of the night, according to a study from Deloitte that also suggested the pace of consumer adoption of smartphones will fall in the next 12 months. The study of 4,000 people, published Monday, showed 10 percent of people look at their device immediately after waking, and 52 percent check within 15 minutes. The numbers are similar at the end of the day with 10 percent looking at their phone immediately before they go to sleep.
