So I bought my new S6 Edge on Sunday. I have about 8 Micro USB chargers. I've noticed that the Fast Charger included with the S6 edge takes much longer to charger than others. I plugged it into my charger included with my LG G2 at 15% and it said 1hr 30min to full charge. I plugged it into my Samsung S6 Edge charger and it said 4hr to Full Charge. Anyone else getting something similar to this?
