Much higher battery capacity than with Series Battery

The advantage of this battery is that it lasts much longer the battery as the original battery. The cover fits perfectly. For someone that does not mind that the very flat mobile now much thicker is a good choice. I got back inside made a matching battery, because my cell phone but was too thick and it also no longer fit in the cell phone pocket. For this reason, I ordered a Zusatztakku, where I can recharge the phone at any time on the road. For me personally, in retrospect, the better solution. Still 5 stars, since there is nothing to complain about and it was announced that the phone will be thicker.
