Seeing as it seems 3G can't be switched off on the 4s and when at home when you have wifi on...does the fact 3G is on effect your usage on wifi? Normally my battery life is great at home with wifi on where I switch 3G off with the 4..
does having 3G on effect your usage at home when on wifi on your 4s?
