I am trying to find the settings (assuming there is one) that will tell my phone to not go to sleep when plugged in. My main reason for this is when I use the phone as an mp3 or Pandora player at work, I like to occasionally look over and see the artwork, press next, whatever, and having it sleep is annoying. My old iPhone would work like this, and I'd like to replicate the functionality. Any suggestions? If this was asked before, or commonly, I apologize. I hunted through several pages and only found tips for other phones to do this, and the search results were no help either. Thanks!
