Have you tried a power down restart? It seems like literally after most every update some people have battery drain issues and at least for some the fix is a power down restart or possible a factory reset. A factory reset means of course you have to back up your activities before doing a reset and would need to redo your profile after your reset, so it's advisable to try a power down restart first.
I also recall some folks having sensor setting issues after updates, I am not recalling the specifics but it had to do with sensor settings getting changed to modes where they drew power continuously, one of them might have been HR monitoring during sleep. Anyway it might be worth looking through the settings before going to a factory reset.
@CARMEN_F So I'm kind of assuming that a restart helped since you asked another forum poster if they had done a restart (slow screen problem). It's great to get some feedback for the general knowledge base of what did and didn't help.
