It’s not different. In theory recent macs are supposed to “learn” about your habits and lock charging at around 80% when you’re not going to move a while (“optimised battery charging”), but from what I’ve heard it’s not super reliable. And I’ve never seen it work properly on my iphone, whose usage is about as reliable as you could be (plus iOS has all the alarms so it knows exactly when I’m going to wake up) so I didn’t exactly have high hopes.
A more reliable solution is to manipulate pmset directly, or use something like AlDente which handles it for you (the paid version has lots of extra features but the free one suffices to avoid charging above 80% by default).
Obviously when charging time arrives you need to realise yourself and plug in somewhere between 20 and 40%.
The only annoyance is the magsafe’s LED remains amber even when the mac stops charging at 80%.
On my iphone it pretty reliably charges up to 80%, waits a few hours and then charges to 100% when I put it on the charger for the night.
On my m1 air I’ve only known it to charge to 80% after a period of several weeks where it was docked. As soon as I started using it away from power for significant amounts of time it went back to charging to 100%.

I just checked what happened last time. I went to bed around 2300, it quickly charged to 80% (getting there a bit after 2400), then stayed there until 0200, at which point it decided to charge to 100 which it had reached by 0400.
As it does every workday, and has since before I had that specific phone (which is 2 years old), the alarm woke me at 0600.
So over a 7h night it managed to spend more time at 100% than it did at 80. I’m not going to say I’m impressed, because I’m not. Based on usage pattern I could see it fail to reach 100% by 0600, but I don’t think I’ve woken at 4 once in the last 3 years.
