Since I've updated to Sonoma I've been having issues with battery management on my M1 MacBook Air. The system says the battery isn't charging because it is rarely used on battery (which is true) but it actually keeps charging the battery anyway. This kinda defeats the point of optimized charging. Is anyone else experiencing the same issue?

You are over-worrying this. As others have pointed out, even in desktop mode or after being at 80% for some time, it will once in a while charge up to 100% and be there for a while then go back to 80%. Also, sometimes it stops at a different level than 80%. Like 76%. Or something else. Staying all the time at 100%, or 80%, or some other value is not ideal for this type of battery. So the OS tries to vary things some and periodically it "exercises" the battery, research has shown this can extend the life of the battery. Since we don't have access to the "algorithm," we can't tell why it is doing what it is doing and when it might change things. Also, Sonoma MIGHT have updated the algorithm (versus other OS versions), so just because something changed does not mean there is a problem with Sonoma.
What you are doing is like obsessively measuring tread wear every day or every week on automobile tires. Laptop batteries, like automobile tires, wear out over time and have to be replaced. The Mac OS is just trying to "drive the car" in a way that maximizes the life time.
I tried to start from scratch and erased my Mac without restoring but with no luck. The problem persists.
I factory reseted mine and left it on for 3 days and it started working.
Take control yourself. Use AlDente or something similar.
That’s how I always do. I’ll try again with wipe, basic configuration and let it stay few days with original wall charger. Fortunately I can move with my work on my iPad for that time.
It didn't worked. I'm helpless.
Agree, this is not functioning as it did before Sonoma.
It could be a power cable issue, or the connector issue. Try using another power cable. Also, usually all such problems go away if you shut down the MacBook for a while, and reboot.
Optimized charging not working in Sonoma?
