First, the positives. The performance of the battery is good. Long standby time and sufficient capacity for long conversations without the phone must immediately return to the charging station.
The negative is that the battery does not really fit into the Fritz! Fon. It is estimated that 1mm too thick. One gets the cover while again, but then has an edge on the rear side of the phone. While it has no functional disadvantage, but it's really ugly.
