G21 330i xDrive Parasitic Battery Drain?

Hello everyone,
Hope you are doing well.
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
