briefly touched on above arises when this mobile is always the problem of short battery life, so I needed a more powerful battery. He was promptly delivered tested through its paces. The mileage is of course much higher, as the volume - that was known - hence the supplied battery cover which makes the in very narrow Cell something Globig. Unfortunately, the lid has not properly closed, you had to play a bit until it went. With a phone cover of this battery is also not compatible; just no longer fits the phone into the docking station.
