Most of the updates are detrimental to the battery ,most..Some firmware updates really does affect the battery life and in turn affect the rate of battery degradation.
However some does improve battery life as well like how IOS 15 has battery life on iPhone 12 for me compare to the latter few IOS 14 firmwares those are really bad.
