The methods laptops used was in the BIOS and controlled by apps or the BIOS. As I understood it, it changed the charging parameters that were being used rather than run something extra.
Of course, I also think the whole thing is pointless. Again, you are basically saying, "I want my battery to last longer so I won't actually use it but I will plug it in twice as often."

People keep saying "phone/laptop manufacturers know what their doing" or "phone circuitry already does this" yet batteries keep dying after a few years. Charging your phone once to 100% is disproportionately more damaging than charging your phone twice to 90%. Think of it like filling and emptying a cardboard box to 100% vs. 80% 365 times.
There are studies regarding this, %40-80 is the most efficient cycle but you don't have to go out of your way, anything below 100% would help. Some laptops allow you to do this, some Samsung phones do this by default and that is how they can guarantee 95% battery retention after a year. Under normal circumstances you can expect 80% battery retention. Some of this extra 15% comes from the reserve power but most of it because there is a reserve power.
Other companies might be doing what Samsung is doing but not all, so it would be nice to have the option.
