My Samsung S3 Battery Management 18 months of age becoming increasingly catastrophic, I had to bring myself to buy an additional battery to prevent "dry failures" untimely. I found that it was not easy to find the replacement battery "miracle". Number of guests reviews described disappointments when shopping. It seemed to be "least worst" diverse and varied offers, because in reading the customer reviews between the origins batteries that are not, those who are not, or not work at all, or worse ones that could be dangerous. A real puzzle. Concerning product delivery and no worries as delay, perfect. In practice, it turns out that this battery works pretty well. From there to ensure that it has the same autonomy as that of a new machine, I'm not sure. But I managed to hold a day, knowing that of course this depends on the application that it is necessary to use (Wifi is catastrophic in consumption). To secure the whole, I bought a small battery charger in order to always have a second charged battery. What a calamity these batteries!
