I'm now on a used iPhone 4S running iOS 7, but the subpar battery is really starting to get to me. I really like the form factor and the 4" of the iPhone 5 series is probably the largest I'm willing to go. (I've thought about the Moto X, though.) Of these three, what would you suggest? iPhone 5, iOS 6 iPhone 5, iOS 7 iPhone 5c, iOS 7 I prefer the iPhone 5 form factor (lighter than the 5c) but I'm trying to figure out which of the three has better battery life. Unfortunately the reviews are all over the map. At this point from what I can read, it looks like iOS 7 was not great for battery life. So as long as I am willing to put up with iOS 6, should I just get an iPhone 5 running iOS 6? Thanks for your input.
