iPhone draining when shutdown

iOS and iPadOS

Hi, all
Yesterday I turn off my iPhone xx when I went to bed because battery was at %54. When I turn on my iPhone battery was %20. Sunday same issue. When I went to bed Saturday, battery was 40 and when I turn off phone it was zero. What is going on?

Don't worry about the actual battery. The battery reporting mechanism (software) can sometimes be all over the place. Try doing the latest updates.

I have iOS 12.1.1 . I went to the apple store yesterday and they could not find any problem. The battery is in excellent shape. They could not find anything wrong with the iPhone. It is strange.
