Thank you cause i think that would be nice if they do have an app like that :) Options Log in or register to post comments Comments I don't think it is needed. I don't think it is needed. All you need to do is just look at your status line. and if it says charging vs on ac power you will know when it's full. Besides when plugged in to the computer it takes about an hour and a half to charge. Results may varry.
