The back of the case has a noticeable bump where the battery is located, but still has a low profile, only slightly thicker than most normal cases I’ve tried. The front of the case fits pretty flush with the screen, except for a small lip around the top and bottom, extending a few millimeters from the screen’s level. The protection value of the case itself seems decent. The front-facing speaker holes are an unexpected yet necessary bonus. I suppose it was the only place they could have added speaker holes, but having the sound aimed at your face rather than away from it actually helps the sound quality quite a bit.

Mophie added a bit of extra functionality to this area with forward-facing speaker holes, which basically serve to redirect the sound from the speakers on the bottom of the phone. The “chin” of the case adds about 1/2” of height and is primarily needed as a pass-through for the case’s Lightning port to the phone’s Lightning port. It also provides a solid grip that the XR lacks without a case. It has a matte finish and feels good in the hand. The red model of juice pack that I was sent almost perfectly matches the shade of red that the iPhone XR sports. A side view of the juice pack air, showing the gradual increase in thickness for the battery pack. The case also makes it slightly taller and wider, and close to twice as thick compared to the naked iPhone. That’s not terribly heavy, but it’s certainly noticeable. For reference, the iPhone XR is 6.84 oz, so the addition of the case makes it roughly 40% heavier.

The juice pack air weighs in at a mere 2.7 oz.
