The original battery of the Motorola Razr V3 is told not one of the most durable. Mine was always empty at the end after about 1.5 days standby. The ordered here replacement battery I am completely satisfied, however. Unwrapped, charged and after 6 days of standby still charged more than a third. Excellent. Even the original battery from Motorola has not persevered in the new state for so long. Now I have joy in my phone again and will first dispense with the purchase of a new mobile phone!
