Right, i mean a setting to extend battery life span, where fast charging usually do the opposite.I guess you're talking about physical battery life span.
Like: There could be profile settings preventing the battery from physically dying earlier, right?
Interesting theory, but I think these profiles rather aim at providing real time benefits.
Like you either want to have more performance now and except battery to go down faster for the moment, or the opposite.
Nothing in the manner of long term benefits.
But on the other hand, I'm also just guessing.
I guess charging wattage only matters in battery charging speed: a lower one will charge the battery slower and with lower temperatures, with less stress for it, which is good on long term (many charging cycles).
But we are just guessing
