I have a Lenovo laptop and it has the feature it describes. You can set a manual charge cut off or do the following:

"Optimize battery lifespan (automatically change for me)"

Right now, it seems to not charge the battery unless it gets under 96% charge, and then it charges to full. Its language implies that it changes that charge level based off of a good compromise between battery life and charge. As someone who doesn't want to think about the battery issue, I really love this feature.



Macbooks do the same, but I haven't found a way to change the threshold. 90, 85 or even 80% would be fine for me.
