After the last update of the Android original battery lasted not more times a day with the switched mobile data. On vacation, he then completely abandoned and wanted to transform it into a ball. Since then I ordered the large battery. The Galaxy S2 is now more difficult but that does not bother me. The battery cover fits like a glove and has the ribbing of the original cover. The term is now nearly 3 days at the same use. I have not looked back. But you have the original car holder slightly modify to set the phone back fits properly.
