Either it is in this battery is a fake, or is it just too old. In standby - mode, it holds more than 2 days under normal conditions (3 short telephone calls and a few photo's) a maximum of 1 day. The figure also does not describe exactly the delivered goods. The supplied battery looks more like a fake. Could also be a bad License replica. The original has in any case a brushed aluminum finish and a hologram. The hologram is missing in this battery and the fnish consists of a silver glued plastic film. Since I did not expect much at this price Eh and I have it for emergencies only this, he still gets 2 points, after all, it works.
