I tried the Qi card is glued on top of the battery, but the charge 1 does not always put Started 2 - tightness of my S5 was not total (map relied on a seal back cover). This Samsung back cover is a bit thicker and a bit heavier than the original hull of the S5 but it's a detail that we forget quickly. it works perfectly, charging starts automatically. Contrary to what I read, the charge once reached 100%, remains at 100%. I personally use inductive chargers NOKIA DT 900 and DT 601: no worries. A real pleasure to do without cables.
