Same! Though it was some liquid glass distortion of the phone or something.

And then I stared at the line about "remarkable all‑day battery life" and wondered what is so remarkable about that. Anyway... "The new iPhone Air MagSafe Battery has a thin and light design that magnetically attaches to the back of iPhone Air to extend battery life during busier days." So you can always turn it into a normal thickness phone with normal battery life it seems.
