世論 What Japan Thinks

A rather interesting survey by iShare looked at a topic that I’ve covered before, namely mobile battery recharging frequency, but with a look at a new angle, specifically what causes the battery to run down.

Demographics

Between the 23rd and 28th of June 2010 462 members of the CLUB BBQ free email forwarding service completed a private internet-based questionnaire. 56.3% of the sample were male, 32.9% in their twenties, 33.5% in their thirties, and 33.5% in their forties.

I recharge my phone about once every three days, but I blame that more on a two year old battery than on my occasional email habit.

It would have been nice to also see a breakdown of recharging habits against smartphones and feature phones.
