The battery-king turns out to be strong endurance runners. Although nominally little more than the original battery it showed in the practical application of a significantly longer standby and operating power. Well, the original Samsung battery was now for 2 years in operation, has at this time but really never kept. And the difference by the battery-King is significant. I have to made no specific measurements, but appreciated the operational endurance has doubled, and the price is very acceptable. Therefore 5 stars.
