The reason for this problem may be that the installed battery is not a brand new genuine product. This message will appear in the newer models of iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone XS, iPhone XS Max and iPhone XR. This is a battery verification mechanism added by Apple to ensure the safety of batteries and equipment. If you see this message, there are several situations as follows:
1. The battery of this device has been replaced and may not be a brand new genuine product.
2. The iPhone battery has been replaced, regardless of whether it is an official genuine battery, as long as the battery is replaced by an unofficial after-sales service, this prompt may appear.
