Samsung should add the battery health feature so then it can help users users know when their battery needs to be replaced and also to let users monitor the battery capacity.
You can check in the phoneinfo app from the Playstore in the interim @Mohammed_44
I'd suggest to send your feedback to the Samsung Developement Team via the Samsung Members App too.
@Darekb81 has this been officially confirmed by Samsung in one of their blogs pages etc ?

I would recommend not to root your phones @Mahammad as this will void the warranty. We have good news for you! You can now check your battery status using our Samsung Members app. This comes preinstalled on some on our phones. To access to this head into the Samsung folder> Samsung Members> Get help> Interactive checks> Battery.
If you are unable to find the app there, you can download it from the Galaxy Store.
@Begunok: You can check the battery capacity by opening the Samsung Members app > Get Help > Interactive Checks > Battery. Alternatively, head to Settings > Device Care > battery to find your usage information.
