"Accessory Not Supported"
iOS 11-12 can be picky about accessories. The Apple customer forums have articles about this issue every time Apple updates the iOS.
(iOS 11-12 doesn’t always report the error above – sometimes the phone case turns on and the phone just doesn’t start charging)
Other users have solved the problem with this process. (including my phone)
- Turn on your charging case. When the error message appears, just dismiss it
- Turn on Airplane Mode
- Turn off the device by pressing the sleep and wake button together until the screen turns black and a slider appears. Leave the device off for 2-3 minutes.
- Switch your device ON by holding down the sleep and wake button again, then, turn airplane mode off.
That's it. This fix has worked for everyone so far.
This article applies to both types of SMRT battery cases for iPhone 6, iPhone 7, and iPhone 8 and plus models: Our Ultra-Slim iPhone Battery Charging Case, and the new SMRT Magnetic Battery Charging Case.
