How to Set up the iPhone Duo Case and Turn on Shift Left Edge

The iPhone Duo Case is a thin, two-part case that wraps both sides of the phone and attaches with adhesive. Once it is on, a prompt on the inner display points you to a setting called Shift Left Edge, which moves outer display content away from the front edge of the case.

The case costs $79 in sand or navy blue. The iPhone Duo Folio with Kickstand costs $129 in navy blue or taupe, and both work with MagSafe, Qi2 25W and Qi-certified chargers. Third-party options are in our best iPhone Duo cases roundup.

The Case goes on in two parts

Place iPhone Duo with the outer display facing up on a clean, flat surface, and make sure the phone is free of dust and debris. Peel the adhesive liners from the inside of the case.

  1. Align the top and bottom right corners of the front cover with iPhone Duo, then press along the remaining edges with gentle, even pressure.
  2. Place the top edge of the back cover, the one nearest the camera, first, then align the other edges and press gently.

Shift Left Edge makes room for the case

After you press the back cover into place, a prompt appears on the inner display and directs you to Settings to adjust the outer display for the case. Follow the onscreen instructions to make the change.

You can make the same change at any time. Open Settings > Display & Brightness and turn on Shift Left Edge, which shifts the outer display content to make room for the front portion of the case. It is also one of the 12 settings worth changing on a new iPhone Duo.

The Folio adds a kickstand

The iPhone Duo Folio with Kickstand has an integrated kickstand that supports a wide range of angles for reading, viewing content or FaceTime. It folds away neatly when you do not need it. Both cases have built-in magnets that line up with iPhone Duo.

Both cases charge wirelessly

The built-in magnets are there for fast wireless charging, so neither case needs to come off to use a compatible charger. iPhone Duo can wirelessly charge up to 50 percent in around 30 minutes with a MagSafe or Qi2 charger.
