After a long time of users asking, Valve has actually added an official Battery Charge Limit setting in the latest Steam Deck Beta update so you no longer need to use third-party tools.
Consider two decreasing lines, one with a slightly lower slope. Now imagine the steeper line starting higher on this graph, eventually the lines will cross and despite starting lower the shallower line will be higher.
You’re missing the point. Obviously the battery health will degrade faster without the feature - otherwise there’s no point even having it.
The point is that the consequence of two years of heavy battery degradation is the total capacity dropping to… Around 80% of the nominal capacity.
Which means all you’re doing is limiting your battery artificially to avoid having it limited by the actual chemistry later on. Which is analogous to amputating your arm today because five years from now you might develop a disease.
80% is 80%, there’s no “80% that will last a lot longer”

… do you know how batteries work? Or how they degrade?
I mean, 80% corresponding to X mAh battery capacity. It will stay at that value for much longer.
