I had an M1 mac at my last job. There were constantly things going wrong with it. I don't have any noise issues with either my personal Surface or my work HP. My Surface has 4-6 hours before it starts conserving power. Not sure what the battery life is of my work machine, since it picked up the idea from Macs to not provide many connection points for you to attach hardware to and it has to be attached to a dock to be usable. Probably the thing I hate most about Apple is other companies see users will still buy their products when they strip out features, so they copy that crap.
