iTWire Monday, 12 April 2021 11:49 Aussies spend almost 17 years in a ‘lifetime’ on their mobiles Shares The average Australian will spend 16.6 years of their life on their mobile phone - equating to 5.5 hours every day or a total of 145,800 hours - based on the average age of around 10 years old that we get our first phone - and average Australian life expectancy. At least, that’s the estimate of Aussie mobile phone use over a lifetime of scrolling, tweeting, watching, liking, and reading, by reviews.org, which surveyed 1,000 Australians about their mobile phone screen time - then factored in the average number of years that we own a smartphone - and compared that to current average life expectancies, and calculated against the average number of waking hours (about 16.7 hours).
