I am thinking about getting my first smart phone and read a comparison between the galaxy S3 and the iphone 4S. they said the galaxy's battery runs nearly two days of what they call 'normal use' compared to the iphones 1 day. My girlfriend has the iphone and she def has to charge it every evening so i cant imagine they are too far off. With larger display, faster procesor and 4G(which i hear draws on the battery more). How the heck does the iphone have nearly half the battery life? Is there some glaring feature im missing?
