Since the original battery has partially discharged more than 30% with me overnight, although everything was on energy saving (WLAN off, display goes dark, all applications closed, etc.) If I wanted to try my luck with this battery. It fits very well into the mobile phone and looks well made. At first I was convinced, although I always did everything as I went over 2 days out on a single charge. In the first two nights of the battery also lost only 8-10% of its energy. Well just now (since the 2nd charging) I come barely longer have a single day, there, overnight losing now 27%. Too bad, the first impression was so good that I also wanted to equip equal my husband's cell phone with this battery, luckily I left it and did not again 14 kicked the window.
**** **** Supplement I was still the end of May of the customer service contact with the info that there was probably defective batteries. The free new battery was sent quickly. Test after about 2 1/2 weeks, I'm happy. He keeps a little longer than the battery 1, but if he really brings the promised performance, I can not judge. I now forgive 2 star more.
