Some samsung tablets (and phones, I think?) have an option that does this - it remaps 80% so it appears as 100% and won't charge past it. Nice way to improve battery health for a device that spends a good chunk of every day plugged in. A fun side effect of this is that the tablet can boot while at '0%' battery, and then it will automatically shut off a little bit later to avoid dipping below the safe range - presumably '0%' is actually like 10% or so.
