After a year now the battery lasts on, what it promises. The normal battery I have a day rarely managed without being empty. The rear panel was not very often taken from me, is of the same material as the normal back. So far, no signs of wear, although I everywhere take the phone out of its case with back. The larger battery needs a little more space, the mobile phone is now a few millimeters wider than before, the back thus forms a smooth surface. Buy recommendation.
