Battery life in Iphone 12 pro

I didn't have Iphone since the iphone 4 exactly 1 year ago I bought the iPhone 12 pro and the battery can't even last more than 12 hours at 6 pm I don't have a battery at all is it normal?

when I check the battery life cycle it's on 89% I only charge it with the original charger since I bought it and at night...
