CAUTION: My battery came with me on 12 August. At first he was very good and held particularly long. But after a month came the problems. He was at school so hot that I had to put my cell phone out of his pocket on the table. The power fell. Today, 7:12, my phone has gone about thirty percent at one time. I tried to restart it. Not. So plugged charger and it actually started. But it had only zero percent. The battery was warm but understandably because I used my cell phone all day. I was never that he is at 30% off. So I removed the shell and realized that the battery has very bloated. If the cell phone on a flat surface so it teeters. After almost four months of a very, very negative development. I have the battery and dispose now procure me a new one. This is a rechargeable battery does not last forever and that's clear he is going even broken after a year already relatively normal. But for scarce four months? Only two stars but because he initially went very well.
