The first order: the battery does not hold the phone more than 2 hours, I refer 2nd order: perfect phone, Windows phone I like a lot and is easy to use. I just regret the lack of apps .... The battery is rather correct and shall hold at least see the day which is not bad for a smartphone. It is thin and light. I just have to prefer a slightly smaller size because the model is very large and is difficult to handle with one hand (especially when it is secure by a cover). The Samsung Ativ S mini would have been perfect but sadly Samsung did not want to continue on windows phone which is a shame given the quality of it! Probably one of the best phone I've had to date. I've had it about 5 months
