I agree with many reviews before me. Have the charging shell though purchased from another provider, but still want to contribute my opinion here it. From the beginning I had problems with charging the charging shell, it did push back with tries later I put balls of aluminum foil in the grooves on the phone. That was all short-lived. I had actually resigned myself and my Lumia 925 is always loaded with the normal power supply ... Today I was here attention to the contribution of "Stefan Betz" by the reviews and had first made easy provisionally cardboard in the bottom corners of the loading cover and lo and behold, that Laden worked right away! For me this is a clear failure on the part of Nokia design. They should start an Inquiry hollow action for your bungling and liberate all those affected by this faulty charging Orders! According to the reviews here it is 50:50 which one gets a proper and functional charging case! Good luck with your purchase! ;-) Update: I have looked at the "contact group" of the charging shell again accurately, while I noticed only now that the "contact group" is not exactly in the slot sitting. With your thumbnail, I managed to push this contact group down. Go heavy. I am going to the charging behavior observed only once ...
