So after years apparently bezügl an ongoing issue with the various suppliers. If the battery quality, I have consciously decided on this new dealer and a more expensive price -who has been going as a freshman, and the most expensive providers in the competition and then sells scrap. Battery: The battery keeps its promises and I am very satisfied. Forgot my cell phone in the standby mode and leave the battery has held for 7 days until it was empty. Just like my old original battery it has previously also done. In my day operation of the battery lasts even longer and was for a week half full (half empty), but have to say that I have the phone is not all day and rarely on the phone and mainly SMS ship. I now hope for all buyers to me that this seller retains its quality standard.
