We use Video Tube on our iPads. The app is great but something that is frustrating is that if the app is open the iPad will never go to sleep, even after the video is done. My kids always watch videos and just put it down and walk away which leave the iPads always with very little or no battery juice left. I don't see any of the reviews mentioning this however I also don't see any setting for this. This occurs on all three of our iPads so it isn't an isolated event. Does anybody else experience this? Is there a way I can have the iPad go to sleep if this app is open? Thanks.
