iOS 17.5 battery drain

I updated to iOS 17.5 the day before yesterday and since then noticed that my fairly new 15p was draining fast enough for me to see the % dropping when i glance at the battry icon every 5-6 mins. I know that it is not any of my settings or apps since I've already done most of the recommended actions to save battery life. On iOS 17.4.1 my battery was much much better. I would end a typical day with 30%. Currently it looks like I would reach 30% a couple hours earlier than usual. My battery health is at 100% and nothing has changed on my phone other than the update.
