iphone 11 pro battery life problem 17.0.3 ?

I installed iOS 17 on my iPhone 11 Pro the day it was released, and my battery charge was fine. However, when I installed iOS 17.0.3 when it was released, my battery started to drain rapidly. I have to charge my iPhone twice during the day. So, with the last update, the battery problem was not solved, it got even worse. .I hope Apple authorities will fix this situation. MY BATTERY WAS CHARGING FINE WHEN I INSTALLED iOS 17 WHEN IT WAS FIRST OUT.
