i have owned a Samsung A900 for over a year now & talk on it for several hours a day, it is my only phone. This thing has the best battery life & I am very rough on cell phones and it keeps going. It has fallen off a moving car, been dropped more than I can count & had water dripped on it numerous times & keeps going. I had to get it replaced under warranty due to the tech said I had talked over 3000 hours on it & he said most people never talk that much on a cell phone. Oh & I never turn it off unless I am resetting it. So I would highly recommend this product to anyone.
