世論 What Japan Thinks

Perhaps I just don’t get enough phone calls and mail, but I’ve never had the experience of having my mobile phone battery run out on me. However, I have recently started regularly recharging my mobile at work as I got as a free gift at a conference a USB cable with multiple adaptors for recharging mobile phones and other devices. To discover what other people do about their mobile batteries, japan.internet.com reported on a survey conducted by Cross Marketing Inc into mobile phone batteries.

Demographics

Over the 30th and 30th of May 2007 300 mobile phone-using members of Cross Marketing Inc’s online monitor group successfully completed an online questionnaire. The sample was exactly 50:50 male and female, and 20.0% in their teens, 20.0% in their twenties, 20.0% in their thirties, 20.0% in their forties, and 20.0% in their fifties.

Although battery technology is progressing and integrated hardware reduces the power consumption required for many features, as phones sprout more and more features and the manufacturers are pressed by market demands to reduce weight, the battery is often the first component to get slimmed down.

Note that for DoCoMo at least, and perhaps the other makers too, if you have kept the same phone for over two years they will give you a new battery pack free if you ask.

Note also that I reported on a similar survey on mobile phone batteries last year.
