I've enjoyed using WhiteNoise on flights, but was really disappointed to use it the past two nights on the timer for sleep. I had it set so that after the period of time I chose it was supposed to "Exit Application." When I went to bed the battery was showing at 85% full. I had even enable the airplane mode settings so that the phone wouldn't be getting texts, trying to access wi-fi or 3G, and didn't have any other apps that I could see running in the background. The alarm on the phone never went off this morning, and when I checked it, the phone was completely drained. Had to charge it while I got ready for work. The same thing happened the night before.
What's wrong? I have an Iphone 3G, and am running 4.0 OS on the phone; the app is 4.0.5. If this is a routine problem without a fix, the appl isn't particularly useful. I don't want to listen to it before I got to bed and then turn it off before I fall asleep. That's the whole point ...
