How to check the battery cycle count in iphone 11?

Hello AmanBharadwaj, 

We understand that you’re looking for more information on the health of your iPhone’s battery. 

Your iPhone has some built-in information available to you in Settings > Battery > Battery Health. You can learn more about what that Maximum Capacity percentage means here: iPhone Battery and Performance Battery cycles are not a statistic that is viewable from within Settings or via the built-in diagnostics on your iPhone.

Thanks.
