Visually this battery is indistinguishable from the original. The performance is about the same. I hoped a greater power than the old, but does not have the battery. What I do have to mention the big downside, is that I now for about a year had to remove the battery again, as he had greatly enlarged its width and thus the mobile phone cover has pulled the trigger. Things did not care either way and the performance was still the same, only locked the phone holding back on. Because I do not want to risk that I damage something, the battery lands now unfortunately on the scrap.
