You have not provided more details such as the iPhone model that you are using and the iOS version that is installed on it. My response, therefore, will be a general response just like your question.

1) Double check to ensure that you have ample free storage space available on your iPhone 11. Open Settings ➡️ General ➡️ About ➡️ Available: Here you will see the available storage space on your iPhone. You should maintain at least 10GB or more free storage space for the iPhone’s efficient operation.

OR

2) You may have a poor battery condition which cannot provide sufficient power for peak performance. What is the Battery Health of your iPhone? Open Settings ➡️ Battery ➡️ Battery Health and let us know which percentage you see for Maximum Capacity. Also note what is written under Peak Performance. 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.
