TL;DW: Fast charging over 2 years only degraded the battery an extra 0.5%, even on extremely fast charging Android phones using 120W.

And with that, hopefully we can put this argument to rest.

    You’ll find that based on 3.7 - 4.2 that most li-ion batteries are indeed charged from 0-100 and not 20-80 as you previously claimed. Manufacturers have no reason to overprovision consumer products that are made to be replaced in 5 years or so.

      Yes, that’s what I said. You could go higher and lower, and it would be reasonable to do for a short-life device, but they reduce it to extend the life. Mapping voltage to percentage is arbitrary.
