This update includes the following bug fixes for your iPhone:
Battery may drain more quickly than expected after updating to iOS 15.4

iOS and iPadOS 15.4.1 fix an AppleAVD issue that could allow an application to execute arbitrary code with kernel privileges. Apple says this exploit may have been actively exploited, so it is a good idea for all users to update as soon as possible.
