Battery draining faster after October security update

[SSKrocks]

I noticed that the battery is draining faster after the october security patch. Is anyone facing the same issue?

Please let me know what to do if there is some issue

Enable power saving mode. Restrict background apps from using power in background. If you find my suggestions useful, then plz accept it as a solution by tapping on three dots on right hand side.
