Mophie Juice Pack anyone?

[IMBA666666]

Anyone else using Mophie Juice Pack for their S7 Edge? Ive been using it for a week now. And everything seems good. Except that i cant stop the case from charging the phone while im charging the case. In short the case is constantly charging the phone. Is there anything i have to worry about? I usually charge the case when my phone has around 30% of battery left and the case has 0%.

Good question, I'd like to know if there's any negative effects from this...
