I upgraded to iOS 18.4 middle last week, and noticed battery starts to drain crazy since April 12th, my device is iPhone 13 Pro, battery used to last 2-3 days, now, I charged it to 90% before going to bed, and wake up at 26%, batter is still healthy.

iPhone 13 Pro, iOS 18
Update: about 3 days later, abnormal battery drain has stopped.
Here is what I have tried:
Hope anyone experience the same get your phone back to normal as well, and ASAP.
You should be charging overnight, every night. If you do, and the phone does not need to be charged until the next night, then it is working as designed.
There is never a time when any smartphone is doing nothing, so it uses energy 24/7. If you charge overnight the nighttime usage will come from the power source rather than the battery, which will extend the useful life of the battery.
