I had to buy a new case for a 6s and while it seems to be working ok when I check the battery level on the phone it's name "Apple Accessory" rather than "Smart Battery Case" which is what it used to say. Has anyone else seen this?
Hello and welcome to Apple Support Communities Kentishman,
I see that you're not seeing Smart Battery Case when checking the battery level on your iPhone. I can understand your concern since the old case displayed it that way, and I'd be happy to provide some information to try to help.
Let's have you go through these steps to see if you can get the Smart Battery Case to display.
1. Make sure you're running the most current version (11.2.5 ) of iOS 11.
2. Remove the iPhone from the case
3. Restart the iPhone
4. Return the iPhone to the Smart Battery Case
5. Test to see if the issue remains
Thank you for using Apple Support Communities. Have a great day!
