I have this battery and my wife has the standard edition. I must say this battery does last at least three time longer than the standard. I charge it maybe once every two weeks and thats with the power save options enabled and with the GPS on! I do talk from time to time but even then I only need to charge once a week. That beats the standard battery charge time of every other day hands down. This battery does make the Samsung a bit heavier and thicker but the extend charge to charge time is worth it. I would highly recommend this upgrade!
