MaPo drew attention in his review on how to recognize fakes (title here: Original Samsung - purchased only from Amazon). This description I obviously was plagiarized by the seller Inter phones. Such forewarned I checked the charging behavior with the Android app "Battery Monitor Widget" (free in Google Market available). While other 1A Chargers (eg Sony Ericsson EP800) with stable voltage a charging current balance of 400 and 580mA had showed this charger at collapsing voltage only 40mA. This suggests that here scrap was delivered, the addition with its voltage fluctuations can damage the battery quite seriously. The supplied battery charger also was significantly hotter than the comparative device. Even on my part: Stay away from bad replicas. The only bright spot: Inter Phones wrapped back without hesitation.
