iPhone 6s battery draining RESOLVED

iPhone 6s with IOS 12.1

Alert notifications only scheduled for night time hours and motion zone reduced. I tried killing the app and changing the background updating.

Camera points outside with night vision turned off (there is a motion light outside). I’m not sure what else can be done to resolve the battery drain issue. Any ideas?

Edit: All the above has stopped draining the battery and I’m still covering what I need covered during the hours I need.

Does this happen only to the iPhone 6S? Or all iPhones?
