Is there a difference in the quality of the charge put on the phone from a mophie, compared a charge put on through the wall charger? I realize this question sounds crazy, but I have been using a helium since the original shipments went out. When I charge the phone with the case, the phone battery meter goes down so slowly. I charged mine an hour ago with the pack to 79% and turned off the charge, i have used the phone a bunch, and I am still at 79%. I have noticed this several times, the charge from the mophie just seems to last a lot longer. Has anyone else noticed this?
