according to msdn documentation: http://msdn.microsoft.com/en-US/libr...vs.105%29.aspx
the periodic task is run "every 30 minutes (...) the execution time may drift by up to 10 minutes". However these are the times when my Lumia920 runs periodic task:
and so on...
more or less once every hour. My Lumia has the newest Amber update, GDR2.
Is that device specific? Why is it 60 minutes instead of 30?
I'm not doing anything in my background task, just logging to isolated storage and calling NotifyComplete(). The device was connected to AC power and strong wi-fi network (access point about 1m from the device).
The background task is executed and all is fine but it's CONSISTENTLY executed every 60 minutes, not 30...
