The AI tries to predict when you’re going to be leaving it on the charger for a while (like going to bed), and limits the charging to 80% until it predicts you’ll likely need it, then charges it the rest of the way.

They do the same thing for Macs, but it’s way, way too conservative IMO. My M1 MBP sits on my desk on a dock with a charger pretty much all week, and it eventually figures out that it should just keep it at 80%. Until a brief period where I use it on battery, draining maybe down to 70%. When I put it back on the dock, it charges back to 100% and stays there for the next 2 days.

I would be happy with a “Don’t bother trying to learn, just cap it at 80%, I’ll tell you when I change my mind” setting.
