The health information of this battery is not available." And " Maximum capacity" is not displayed.

This happens because Apple earlier added a restriction to the iOS 12 and iOS 13 systems, as long as the battery of the iPhone XR, iPhone XS/XS Max has been replaced by a third party or by itself, regardless of whether the battery is For Apple original, will cause the "Battery Health" function can not be used normally.
