Battery Health Unknown is a message that appears when a non-genuine Apple battery has been installed on your phone....or....if a genuine Apple battery was installed, the installation was not done correctly.
Take the phone back to get it fixed.
Verify that the shop is Apple authorized by using this link:
If it turns out that the shop is not Apple authorized, that will unfortunately open up a new large can of worms.
