What is your Battery Health at Settings > Battery > Battery Health & Charging > Maximum Capacity?
You can also verify if Peak Performance Capability has been limited directly under the Maximum Capacity.

I would also recommend to perform a Force Restart that will do some basic housecleaning and especially useful after an update.

Press and quickly release Volume Up
Press and quickly release Volume Down
Press and HOLD side button until Apple logo appears. This could take up to 15 seconds before you see the Apple logo while holding the side button and you will want to ignore anything else you see on the screen during that time. If you do not see the Apple logo, then try again as it may take a couple of attempts to get the speed and sequence of the key presses correct.
