I use my M1 Air daily for (on average) 10 hours a day (I know..). Bought it new in september 2021 but started really using it around january 2022. It had 20 cycles then, and was already at 94,7%. Now it's at 263 cyles and 85,9%
Still fairly happy with the battery. Sometimes it runs empty in only a few hours, but in 99,9% of the times this happens, it turns out it's Safari drinking all the juice.
All in all, this M1 Macbook Air is the best laptop I've ever owned, dating back to a 'Bronze Keyboard/Lombard' Powerbook G3 and many others in between. It's lightweight, silent, fast and I love the keyboard even more than I loved my 12" Powerbook G4's keyboard.
