I have an M1 mac for work and I am seriously impressed with the battery life. I prefer my asus laptop that I loaded ubuntu on for my daily driver (gaming, coding, fun), but man, I can leave my work machine unplugged all day while running the work VPN, firefox & chrome, remote desktop, vscode, slack and mattermost, and finish out the day with above 70% battery. I wasn't planning to like this laptop but I do.
