Crash on Internet radio stations hit paradise ???

the C4 is actually on top Fritzbox 7490 - it's all down to the battery
the battery is full and suddenly empty, and he has very little power
why you doing here no 2000 Battery purely ??
I've ordered a new battery and hope that disappears the error
If this is the case, I raise to 5 stars

Update
it is not on the battery (but could have more power anyway) Special C4 crashes during Internet radio, specifically by increasing the volume when hit paradise
Why can I say, but is not always, but often - the other channels run optimally
the the battery was only at the beginning, now it remains fully
now there are 5 stars
