Iphone as Airplay Receiver undo

[hartmund]

Hi there,

I just surfed with my phone for about an hour and already lost 20%. I think it?s because yesterdayI followed those instructions on how to use an iPhone as an Airplay receiver. However, I think my battery suffers hard from it. I would like to undo it but deleting the files doesn?t do anything.
I updated to 5.0.1 a few days ago, could my battery be dying because of this?

Thanks a lot!
