Make sure that you have the latest version of iOS.

Attach and remove your case

To attach your case, pull back its top edge and slide your iPhone in. To remove your case, pull back its top edge and slide your iPhone toward the top of the case. Slide up—not toward you—or you could damage the connector.

Charge your iPhone anywhere

When you put your iPhone in a Smart Battery Case that has a charge, your iPhone charges automatically.

Charge your case and your iPhone

  1. With your iPhone in your case, plug the Lightning to USB cable that came with your iPhone into the Lightning connector on the case.
  2. Plug the other end of the cable into an Apple USB power adapter, then plug the adapter into a power outlet.

You can also charge your Smart Battery Case without your iPhone.

Check the charge

As you attach your iPhone to your case, a charging status appears on the Lock screen. The status also appears when you connect the case to power or disconnect from power. If you already attached your iPhone to your case, look for the charging status in Today View on your iPhone.
