The original battery is me then inflated after prolonged storage, so it was useless. Therefore I have decided for this article. I am very happy with this battery. The running time is about a week, roughly so as the original. I now have him since RD. 3 weeks use and yet loaded twice. From the fit her well everything is fine. Error messages on the part of the phone there is also no. I would so buy again and recommend without hesitation.
