Battery drain

I have a friend with a 2012 X5. she is having a battery drain issue. She has just put a new battery in and still getting high battery drain alert that stays in the check control.
She also have a comfort access code being thrown. Alternator and battery are both good. Not sure about battery cable. Any thoughts? Thanks

Does that model require battery registration? Comfort access require a new battery for the remote?

Yes she said it was properly registered

Check the door handles for being warm to the touch. Common for them to cause a draw.
