charging battery on iphone 4s
I am sorry if this is a basic question but I am coming from a blackberry bold (BTW I am so happy I made the switch).
When i place the iphone in the charger, the phone powers up. I would think this would result in a longer time in order to charge.
So the questions are whether the iphone can charge with the power off. If so, will it charge faster than if the power is on and finally, how do you charge with the power off? (do you hit the top button again until the power goes off?,etc.)
With the blackberry, if I turned the power off, it charged faster.
