I got myself this battery, because no longer my original battery ran right and I invite you this day sometimes 2x needed. I chose this battery, because he was both price and visually interesting and especially more capacity than an original battery of Samsung. The delivery was super fast and I started same. The battery has approximately summoned in half, so I know the same from the original. I now took my phone with the Dino-Cell battery pack until it was empty and then I fully charged the Cell Dino times. To be honest, I'm thrilled! The battery lasts really long, I also think that what he promises. From the feeling I can not say whether he lasts longer as the original in the beginning, but in any case this is a tip part and inexpensive. I'll definitely buy a 2nd battery for my wife (S3mini) at Dino Cell. Conclusion: good price good service good article. Many Thanks.
