Poor battery life after iOS 26 update

Hello,

I have noticed a roughly 20% increase in battery usage when upgraded from iOS 18 to iOS 26. My phone is the iPhone 15 Pro Max with battery capacity of 98 %. Has anyone else noticed an increased battery draineged after the update? Any clue when this will be fixed?

Thank you

iPhone 15 Pro Max, iOS 26
