How long each day do you use your mobile phone? graph of japanese opinionNEPRO JAPAN recently published an interesting survey on how mobile phones have changed users’ lives. They got replies from 4,610 people who answered a questionnaire available for one day at the start of February through iMode, vodafone live! and EZweb mobile phone service menus. The sample consisted of 40% male, 4% in their teens, 38% in their twenties, 41% in their thirties, and 17% aged forty and over.

Some of the figures are quite amazing, such as one in four spending over three hours a day on their phone. However, when you consider that the average commute for people is over 90 minutes per day (must find exact figures – I’ve just seen an in-train poster stating that statistic) and many people will be busy mailing or gaming (when they aren’t sleeping), the hours soon add up.

Question 3, on whether people use a fixed or a mobile line at home may very well be biased by people who still live at home but do not pay the fixed line phone bill.

Note also that this survey is self-selecting through a mobile phone menu, so people who only spend a couple of minutes per day on the phone are most unlikely to ever have seen this questionnaire!
