You can very easily replace the battery yourself for less than $100 USD too if it ever becomes enough of an issue that you feel you actually need to do something about it. My M1 Max is at about 88% battery health, but it still gets 4X-6X longer on battery (At full performance too boot) compared to my old PoS Razer laptop, so I likely won't be replacing my battery any time soon.
