My iPhone 11 is decreasing 1% battery health every week, is it normal?

Batteries degrade over time with usage due to chemical aging, that's just how they work.

You can expect about a 1% drop per month with average use on an iPhone.

Apple recommends replacing it when it reaches 80%.

Apple does not sell iPhone 11 anymore. Where did you buy this device from? When did you buy it? What is the current battery Capacity?


Without the above info, it is hard even to guess the situation that you are in.


It would be better if you can please re-post with a screenshot of current Battery Capacity, in order to understand the phenomenon better. Images/pictures speak louder than words. 


Please understand this is a public forum: While attaching a Screenshot, do not provide any personal credentials, such as IP address, Card detail, email id, apple id, IMEI number, Serial Number, Phone number, Order ID, if you are sharing a map ensure your location is not identifiable, etc.
