I believe cycling and constantly discharging and charging a battery is even worse than letting the built-in charge controller do its job and keep the charge. I'm not an expert on battery chemistry, though. All I can say Thinkpads and other laptops have configurable thresholds for quite some time now. And despite me using that for the last 2 laptops, the batteries still go bad eventually. It's supposed to help, and batteries got better, but it's still a thing to factor in.

It’s best to keep it around 50℅ and let it charge / discharge about 5%, and then charge again. See the research links on charge.org (note the bias: his business sells a dongle, but some computers like think pads come with this functionality built in.)
