Without registration of a new battery with higher capacity than the old battery, the IBS/charging system will leave the headroom appropriate to not overcharging your OLD battery.
The BMW charging system will not fully charge its battery to avoid the risk of damage due to overcharging. The technical data available to me/us does not specify how much capacity headroom is reserved.
