Εvery single time i use my phantom 3 battery, mAH decreases. Sometimes though it increases but life is getting lower and lower. I'm at 30 charges, 93% battery life. Almost never went below 15% battery percentage. I assume, by this rate, i'm not even gonna be able to get 100 charges.. Is this a battery malfunction? Maybe a problem? Should i try to return it? Need someone here to answer this question please.
