will Clamshell mode harm the battery of my MacBook?

I am concerned that if I keep my MacBook plugged in during the 40 hour work week, to use clamshell mode, that it will degrade my battery at an accelerated manor.

Your feedback based on a high level of knowledge or facts is greatly appreciated.

2021 MacBook Pro 16 Battery Health 93% after 6 Months Hi, I have read numerous articles on the community, but either their batteries are not depleting as quickly as mine or they are dated (like a few years ago), so I thought I want to bring my case to attention and see if it is normal that this is happening. Model: MacBook Pro 16" (2021) (M1 Max) Battery Health: 93% Cycle Count: 61 Purchased / Start using: July 2022 (6 months ago) I have been aware about the battery health precautions so I do the following few things daily: I use the official Apple Charger (140W) and the MagSafe cable I have battery management turned on Reboot my Mac from time to time Run mostly on power adapter but will still use unplugged from time to time I believe I am already doing all the right things here to preserve the battery, yet at this rate 7% per half a year, I will be at 72% at the end of the second year?! Can I be advised on whether this is normal or should I send it in to Apple? Thanks!

No, it will not harm your Mac. In fact, since clamshell mode required AC, it will omextend your battery lifespan by reducing cycle accumulation.

Keep it well ventilated, do not obstruct its vents and leave some room around for hot air to escape.

Best way is to leave it standing up with USB-C ports on the upper side, I mean, Apple logo will be vertical and upside down. That way you'll have the best airflow, even more on the 2016+ models, that have side vents to suck air in, and push it out through the back, under the screen.
