I have been using an old 3 coil charger powered by an anemic old Motorola charger, to wirelessly charge my old S7 edge, my newer LG G6 and now my S8. It worked on everything except the S8, where I got the "wireless charging paused" reports and it wouldn't charge. I switched to an Anker Fast charger with a thicker cable but still used the old 3 coil, 45 degree charger. So far that has seemed to work. No pause and went right up to 100%. There are lots of reports of problems with wireless charging with the S8. Hope this fixes it. ( I left the OEM Samsung charger and cable in the box to enhance re-sale, in case I decide to sell it.)
