Battery repair kit was delivered quickly and was complete. When 4'er the change of the battery was pretty easy and went slightly out of hand. The battery was sealed in foil. The term is better than it was. With moderate use he holds almost 4 days ago. Here I must mention that we do not have the IOS 6.x it (are probably the last). In order for the 4'er runs but still ziehmlich afloat. Comes as no surprise, the old man was also over 3 years there. Bin far fully satisfied.
