The charger shutting off happened again even when I shut off the phone. Then the next time I left the phone omn and it charged fine through the whole cycle. So no explanation yet maybe the charger just had some bad days.David I have not had that issue charging with the new app. If this is happening to you only while charging at home (as opposed to Electrify America) then yes try shutting off your phone while charging. If it still happens, my guess is something goofy with your charger or outlet.
