Please check this article for suggestions, particularly turning off Background App Refresh.

Also try downloading the app Battery Life which is available for free from the App Store. Test the battery with it and if defective, schedule an appointment at an Apple Store for possible replacement.

Well, you now know what is wrong.... 😟
