世論 What Japan Thinks

One of the nice things about having a big archive of surveys is that when a survey like this one from JR Tokai Express Research Inc and reported on by japan.internet.com into the matter of mobile phone batteries comes along, I can point you at the results of a similar survey from last year and the year before.

Demographics

Between the 20th and 23th of May 2008 325 members of the JR Tokai Express Research online monitor group completed a private internet-based questionnaire. 58.2% of the sample were female, 20.6% were in their twenties, 38.5% in their thirties, 26.8% in their forties, 9.2% in their fifties, and 4.9% in their sixties.

I usually recharge at work these days, with a USB adaptor thingie I got free at a conference once. It’s a wonderfully handy device, and it’s easier to remember to do it at work rather than at home. What I should also buy sometime is a clockwork recharger, or perhaps even this interesting one from Strapya, the solar-powered recharger. It looks really cool, and a snip at 1,995 yen! I don’t know how well it would work with overseas phones though.
