Battery drain on brand new iPhone 12 Pro Max

Does anyone else experience battery drain ? I got a iPhone 12 Pro Max, 3 days ago and it wasn’t on iOS 14.6 after the update. Same day I updated when taking it out the box and a day later the battery is horrible the battery is brand new because it’s a new phone. So the battery should last all day. Apple done a diagnostic test and it came back all perfect ? What could it be ? A software issue ?
