Hello @moe ,
Did you take a look at settings -> general management -> battery to see which app is consuming most battery ? If it is not a system you could try disabling app from settings -> apps to see if it helps increase battery life.
If top usage is from system app or display ,Please send us an error report from the Samsung member’s app -> Beta Feedback -> Error Reports to help us debug the issue. We apologize for the inconvenience and appreciate your contribution to the beta program.
