I noticed a strange (to me) battery drain on the BMW.
Since we went on lockdown, mid-March I tested the battery with a multimeter, and it was like 11.50V after I was not using the car for like a month.
I bought a battery charger, the Einhell CE-BC 6M, and on March 26th, I fully charged the battery, so it was like 12.6V.
Today I rechecked the battery with the multimeter, and it is 12.1V
I was wondering if it can be due to a Parasitic Battery Drain Or if this is normal, and I have to charge it again.
Looking forward to hearing from you and stay safe

Even with the car off and locked, the car still has electronics that are running. The car does self-tests from time to time as well like pushing air through the lines to see if there are any holes.
The battery draining completely normal. These things don't like to sit and if it sits long enough and the battery drains enough, you're going to get a host of warning lights on the dash.
