iOS 18 Draining Battery Too Quickly on iPhone

Since updating to iOS 18, I've noticed that my iPhone's (iPhone 15 Plus) battery drains significantly faster than it did with iOS 17. I'm using the phone in the same way as before, without any changes in my usage patterns or new apps that would explain the sudden drop in battery life.

I've already tried basic troubleshooting steps like restarting the phone, checking for background apps turning location off, etc. but the problem persists. Is anyone else experiencing this issue? Any suggestions for improving battery life on iOS 18 would be appreciated!
