Bin unfortunately been deceived with the purchase. No genuine Battery, but if he would at least work. The supplied battery has probably already thousands of charge cycles behind. The battery lasts up to about 40% still quite good, then the mobile lubricates constantly off, switches easily in running applications and phone calls from. A restore or reset to factory settings was not successful. Have expanded the scrap battery again and again installed the defective old. Go give it back better than this crap. So please stay away from this junk !!!
