I ordered the battery, because my Xperia active after 1 day manifold absolute need is without too much use (some phone calls, about 10 minutes. Internet, some programs as Medscape for cast. 20 min). The Auer up the phone to the charger cable must has, despite slightly higher specified capacity does not improve but rather somewhat reduced. In addition, he just fits in the phone, ie it forces its way just as pure and clamped so that it is hardly removed (eg to change the SIM card or the Micro-SD). The thing is doing what it should, but no improvement or enrichment is compared to the original.
