Hello sis, NFC is not open to all applications in iPhone. its restricted for security reasons. We cannot use it like we do in android. Explained in the following episode.

Which NFC Card you are using? kindly share the product link if you can find the same on amazon.

Regarding battery drain, make sure to update to latest iOS 17.2.1 which also comes with battery drian fix. Then follow these battery saving tips, and that will help to get better battery performance. Observe for 4 to 5 days usage after trying following suggestions and let me know how it goes.
