after 2 weeks copious brew the battery I was very pleased. However, then my phone (Samsung I9000 Galxy) began the battery is no longer fully charge (During the charging cable was connected was the charge level 100%, while removing the charger cable only 30-40% have been directly shown). After complaining of this problem to anchor me another battery was sent immediately. This is now running without any problems, about twice as long as the now two years old original battery from Samsung. The only negative aspect is that the recharge of the battery due to the higher mAh count longer than the original, but it is probably in the nature of things.
