I ordered the battery, because the original battery of my HTC has been going on for 2 years in use and the performance has yet decreased somewhat. But unfortunately I had to realize, even though the battery looks almost the same as the original battery (etiquette in the wrong direction), that not even the battery (listen to music, some surfing, display most of) in "normal" use of mobile phones for half a day by holding. My old battery lasts under these conditions still loose a whole day.
