The original battery started after six months to weave. Sometimes you had to repeatedly open daily and then he ran through 1 week - although the phone has the same amount used. Also, the phone has sometimes simply turned and pretended as if the battery would-if you empty the battery was then anschaltete back yet again and fully.
This replacement battery I no longer have these problems. The user does not even notice that there is no original battery. After several weeks of use I can say that it also keeps longer. Despite constant use I only had approx invite him every 10 days. What convinced me the price and for a product with no memory effect.
