iPhone 11
It appears that you checked the Battery Health of your iPhone 11. The battery health capacity percentage is 77%. If your battery's Maximum Capacity shows a value of 80% or less, then it has gone through its lifecycle and therefore should be replaced, according to Apple.
You can double check this by opening Settings ➔ Battery ➔ Battery Health and let us know which percentage you see for Maximum Capacity. Also note what is written under Peak Performance.
You stated that there is a notification that the battery needs serviced. This means that you will need to get the battery of your iPhone replaced so that your iPhone 11 can begin performing normally.
