Hi @Marktw
Check your devices battery stats settings to see if any app is draining the battery.
A devices battery output will decrease over time and does not have an infinite amount of charge / recharges.
The following processes may / may not help.
Put the device into Safe Mode which disables all your downloaded apps and leaves the stock ones alone which can help to determine if an app is causing this situation if the drain stops.
Then take it out of safe mode and start deleting your most recent apps one at a time.
You could turn the device off and then from a set series of button presses will take you into the System File Cache and delete the files. None of your saved info will be lost.
And or
Back up and Factory Reset.
Finally a Samsung Service Centre or Samsung Experience Store will be able to help you further with this situation by running a diagnostic on it.

The advice I offer is my own and does not represent Samsung’s position.
I'm here to help. " This is the way. "
