The spare battery for the iPhone 4 is accommodated in a housing that fits perfectly with the iPhone. It jerky and nothing wobbles. Even the small plastic attachment for the top sits and holds perfectly. All connections remain accessible for the charging function and connection to the PC a suitable USB cable is included. Is the iPhone completely discharged, then I can charge it through the battery to about 85% again. That seems to me to be a quite reasonable value. If charging the iPhone and only then the spare battery is always loaded first. It remains to mention that the battery switched on via a separate switch or can be turned off and the charge status via four LEDs will be displayed. Of course, the iPhone is a bit heavier with the additional housing, but that does not restrict the use of over previously a. Overall, it is even better in the hand and does not slide as easily on smooth surfaces from. Mir gefällts.
