Something's wrong. Maybe a setting or a random app is preventing your laptop from sleeping properly. You have many threads here saying that MacBooks can go weeks on sleep, and that's also my experience (M1 Pro).
There was a thread about just this issue another day.
I don't daily drive an MBP anymore, only occasionally. But I had one for a week or so, and once or twice I've noticed that my backlit keyboard still had its lights on, which is unusual when the computer sleeps. The screen was dark, though, so it can be confusing.
