I wanted the annoying (often nightly) me - spare and unplugging the charger cable. The cable stuck with me also not constantly in the socket; including the Her - and clearing away. I have now achieved. Replace the battery compartment cover to the new with the built-in charging coil = smartphone is slightly thicker, is even mE better in the hand, back camera is lower than the cap, Samsung logo above center is replaced by Zens small bottom (does not bother me). Connect charging pad with the included AC adapter, plug it into the socket. And S4 hang for charging. Done. The smartphone is actually a bit warmer (bothers me not) and whether the charging process takes longer, I have not tried yet and is not critical for me. About Market Place for less than 1/3 of the original price bought, which was very probably decisive. Otherwise I probably would have ordered the original Bundle of Samsung, because the regular price would have been too high for me.
