spinning circle next to wifi symbol when music folder open I get the spinning circle when my music app is open, it never turns off! Can this drain my battery? on brand new iPhone 5s on ios7
See the answer to What does the spinning circle next to the network indicators on iOS mean?


  Apps can turn on and off the indicator at will, so it's not a 100%
  reliable indicator that data is actually being transferred.


You could make an experiment: leave the phone idle for two hours and check how much energy is consumed with the app on and off, respectively.
