The wireless back does make the phone a bit bigger at the top.
Here is a good review:
"It's not a trivial amount of extra thickness, and the differences are more than cosmetic. The S4 becomes more rounded with the new back cover, which might change the way you hold it. (In our opinion, this actually makes it a little easier to hold.) Finally, in case you were wondering, NFC still works even with the thicker back cover in place, although any form-fitting cases you might have bought likely won't fit with the wireless charging back in plate."
