Have revived after it has suddenly hardly be charged with this battery the ATIV S my son. This manifested itself in the first place by the fact that even though the device was on the charger, the battery charge did not increase in normal standby mode. Charging took hours and worked last only in airplane mode. This replacement battery, the issue has been resolved; Fortunately, there was probably not a defect of the charging socket (or the charger / cable). For the price as apparent genuine clear recommendation from me.
