You mean the GPS icon is in the notification bar on the videos? Can't answer that. I'm guessing that they either have an app running that uses GPS or an app that isn't properly "releasing" the GPS. Yes, it will quickly drain the battery if it is actively used (icon in notification bar). You'd really have to ask the person posting the video for details.It seems as whenever I watch a moto droid video they have their gps on. May I ask why people have their gps on at all times and doesn't having gps on at all times kill your battery drastically?
