The score: The customer service has actively offered to send me a replacement battery, without which I must return the first battery. This is what I wanted to get rid of for now. Anyone who wants good service, must order here! MY RECOMMENDATION! Whether the second battery is better, will show the last update of this review.
Old review: I bought the battery in the hope to get some extra time. In other reviews I had read from increases of about 18%, which is sometimes one hour later. In fact, the battery was found despite Battery Calibration be quite erratic in his discharge cycles. The NFC worked beautifully.
