iOS 17.4 and watchOS 10.4 impacting battery life and heating issues

After updating my iPhone 15 Pro Max to IOS 17.4, the battery drain is very high. It drops 5-10% every 10 mins on just scrolling through instagram. Plus I have noticed the heating issue is much much worse than when I purchased the phone back in September. In just 10 mins the phone becomes as hot as the sun even with a thick plastic case. And its not just my iPhone, my Apple watch Ultra 2 is having the same battery drain issue after updating to watchOS 10.4. While I'm asleep with the watch on, it used to drop just 4-5% in 8 hours but now 10-14% drop in just 8 hours. Please fix these issues ASAP Apple. My battery health is 100% and charging cycle is 94. Phone was purchased 1 week after launch.
