Why is the usage and standby time always the same on my iPhone?
I have 2 possible solutions.


Downgrade your iOS version.
Use a separate battery tracking app. Just search "Battery tracker" on the app store. (As a plus, some come with widgets you can put on the Widget View)


If that doesn't work, then I suggest taking it to the Apple Store to get it checked out there.
