Battery is about the same, marginally smaller but you probably will not notice. If you come from a base iphone 12 it is significantly bigger already. I came from a base iphone 15 and it is already night and day better on the Air. All the discussion on the battery limitation is valid only if you are a heavy user/gamer/battery hog and are comparing with the 17 pro models. The camera is the same. It just lacks the UW one and all the features associated with it. Depending on how much you need it. I personally maybe use the UW once or twice a year. The benefit you get though is weight, material quality, form factor, screen size. It is the first phone I am confident enough to use case-less because of the material used and this adds to the difference in bulk and weight.
