So, I found a lot of posts regarding battery drain issue on different models. I understand my fellow Samsung users are worried and upset about this. But you are not alone.
Guys this is happening after the One UI 7 update to most of the Samsung devices and specially after the May security patch update even to Pixel devices.
Google and Samsung will fix this in the next security update. It has happened in the past with updates and they have fixed if. This time too they will, untill then change a few settings like dark mode and battery saver in settings and wait for the next security update.
