Battery health issue

My battery health showing 98% , please suggest how to bring 100% ( iPhone 11 purchased on Oct 2020)

Battery health will never go back...

You can't restore battery health as all batteries degrade over time and with usage. They are a consumable product.

Have you updated to iOS 14.5.1?

Has it already completed the recalibration process?

NOTE: 98% battery health is not an issue.
