The problem is that a battery case may be too heavy for where I carry my phone (in front pants pocket). Here's the math: 4 oz "base" phone with bigger (by 1 or 2 oz) battery == happy 4 oz phone + 5.6 oz battery/case == too heavy? I actually carried my iPhone 5 w/o a case for quite a while, it's doable. The silicone case that Apple sells for the iPhone 6 is really light and really helps the grip.
