Menu - Settings - Location - Enable GPS satellites It states that enabling this will "require more battery plus view of sky" When checked, it states "deselect to conserve battery" So, the question is, should this be enabled? I imagine for some applications, knowing your precise location should be useful, especially if the turn-by-turn maps are installed and used. I'm thinking to deselect this, and selecting it at times when I need it. So, to check or not to check? Thoughts?
