Hi umaid16,
We understand you're not seeing battery health in Settings. Based on your screenshots, it looks like the information cannot be displayed, either due to an issue with the battery, or because the battery was replaced with one that's not a genuine Apple part.
The following page offers some information about the battery in your iPhone: About genuine iPhone batteries
We recommend restarting your iPhone normally. If you see the same message after restarting, contact Apple Support.
Cheers!
