Brand new Macbook Air M4, battery draining when completely turned off

Yesterday I bought a brand new Macbook Air (M4, 16/512). Battery consumption looks normal when turned on and working, but it also drains quite a bit when turned off for some reason. I completely turned it off (not put on sleep) today at 2PM, and when I turned it back on at 10pm the battery lost 5% of charge, from 76% to 71%. That doesn't seem normal to me, even my old Macbook Pro from 2013 never did that. Is there any reason for this? Is there some sort of problem with this battery?

MacBook Air 13″, macOS 26.0

Even when a computer is powered off, its power source— in your case, the battery—must still provide a small amount of power to maintain user preferences and settings. Otherwise, you spend 20 minutes every morning reseting all your prefs.

A battery is a factory that converts chemical energy to electrical energy. That process does not stop if the device that holds it is powered off.

Look, the computer is new. If this concerns you, by all means have Apple evaluate.
