The negative reviews have a point: Unless this skin is fitted perfectly, it will tend to hold the lid open a tiny bit, waking up the phone and using battery. I found that if I pushed and pulled the skin into just the right position the phone would shut. I then placed a rubber band around the phone at night while I charged it. This seemed to help it "settle in" the skin. After "training" it a couple of nights, the phone seems now to stay closed in my pocket.My complaint is that the skin makes it hard to use the side button for adjusting the ring volume. They should have provided a cut-out for that button as well.
