Battery life depends entirely on the way you use the phone. Samsung's batteries are adaptive, so up time changes with your usage patterns. On any brand phone 18-20 hours of normal use would pretty much be standard for a 5000 mAh battery. If you are a power user and constantly using the device, your mileage would vary, and you might consider the larger battery an advantage. However, if you are a standard user and take battery saving steps, such as lowering the screen brightness and limiting background activity, you might prefer the smaller size of the S24. With either phone, you should be able to get through a full waking day.
