After my original battery was completely discharged after 4 hours had to get a new. The delivery was as stated and the battery is securely verschicket in bubble wrap. I've been using it now for a few months and it lasts as long as the original battery shortly after the purchase of smart phones. With regular use of the common apps (Facebook, Whatsapp, Gmail and some surf) the battery lasts approximately one day. Bin satisfied so far and I have expected for the price nothing better.
