Hi! I have an Galaxy S7, and recently i replaced my battery because my old one was draining very fast. After the replacement with a new battery, i downloaded “AccuBattery” to see the life of it. The battery came with 58% that quickly drained. I searched on google and that’s normal. After the first charge the battery still drained pretty quickly. I checked the AccuBattery and the app said that the battery life was at 67%. But now after a week, the app said the battery life is at 70%. I don’t really know if it’s the charger bad, because is not the fast one that came in the box, is an samsung travel adapter. If i buy a new adaptive fast charger will the battery behave like it should?
