I must be surrounded by non-common users.
My parents charge their Android phones every night.
My wife charges her iPhone4 every day. Same for my workmates.
My cousins all charge their iPhones/Androids every day as well.
Heck, many iPhone users I know carry portable emergency chargers.
Majority I believe are now used to charging whever possible.
Especially considering nearly all phones are now "smartphones".
Many non-geeks use their mobile phones MORE imo. (constant sms, phone calls etc)

Well, if you use Nokia S40 phones, then you can afford not to charge often.
I have a tiny Nokia X3-02 as well for work and I charge every 3-4 days.
