My wife brought down her ipad2 to tell me that it's charging very very slow. Anyway, i plugged it in and, yes, it is very slow. It takes approx. 6 min. to go up 1%. Is this normal. My wife claims that it is much slower now that before. It also seems that way to me as well. 1% in 6 min. is that a normal charging rate? Thank you Oops forgot to say, I bought a new wall charging unit and a new charging cable and have no change - still 1% in 6 - 7 min.
