It's more than just going down to 80%. After a while the battery will essentially fail entirely and not hold a charge, or swell up and push around other components of the computer, and it becomes a fire hazard. I have an M1 MBP and I use it 95% of the time at my desk. I use Al Dente, and if I'm going to be using it away from my desk or I'm going on a trip, I'll just click the button to fully charge it. Even if I forget, the battery life is good enough that 80% is usually enough.
