Obviously like a lot of you, I wish my batter wouldn't drain as fast. I mean, it isn't terrible but it could be better. I have read that disabling mobile data always on will help to save some battery. My question is, is it worth disabling it? Does it really save that much battery? Also, what are the downfalls of disabling it...because it makes it sound like your phone isn't going to always be connected so you might miss calls or not get messages if the mobile data isn't on. Can anyone clarify what exactly disabling this does? Would you not be able to have apps auto-update, like facebook?
