Why is my Smart Case not charging my iPhone

Hello shantene16,

Were you able to follow the troubleshooting steps listed on the article you found? Charge your iPhone with your Smart Battery Case - Apple Support

If your Smart Battery Case won't charge or charges slowly

Follow these steps. Try to charge again after each step:

1. Unplug your Lightning to USB cable from power, and then plug it back in.
2. If your iPhone is attached to the case, remove the case. Then try to charge your iPhone and your case separately.
3. If you have a film, sticker, or label on the back of your iPhone, remove it.
4. Reattach your case.

If you’re using a Qi-certified wireless charging mat to charge the Smart Battery Case for iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone XS, iPhone XS Max, or iPhone XR, make sure that there’s nothing between the case and the wireless charging mat. Also, center the Apple logo—on the back of the Smart Battery Case—on the charging mat. Or place your iPhone where the manufacturer recommends. 

* Charging both your iPhone and your Smart Battery Case takes longer than it does to charge your iPhone alone.

If your iPhone won't charge

Follow these steps. Try to charge again after each step:

1. Make sure that you have the latest version of iOS.
2. If you have any accessories plugged into your case, unplug them.
3. Remove the case.
4. Reattach your iPhone to your case.

Cheers!
