You may always show charging to 100%, but that doesn’t mean your actual battery capacity isn’t being depleted by being overcharged. Your capacity may diminish over time even though it shows 100% charged. just like an iPhone.
There’s a reason BMW recommends not charging to 100% unless necessary. They recommend keeping it at 80% for normal use for precisely this reason. While you may not notice anything initially, but your battery will start losing its capacity despite the charge level shown - again - just like an iPhone.
