Hello
@Nurse21I've got the 12 Pro Max at the moment . At first , coming from the Samsung S10 + it seemed big but after a month of using it as a daily driver I can tell you it is not that bad , you can get used to it .
Battery wise i can tell you it is worth it as the battery lasts a full day easily maybe 2 if you're lucky . :))
The biggest difference you should take into consideration is the camera . The camera on the Max Pro is the best they have at the moment . and the lidar scanner helps the focus be almost instant .
My opinion is to go for the Max Pro even if it seems a bit to big
