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.

What you call 0% or 100% on a battery is an arbitrary number anyway. Absolutely never do this for safety reasons, but back when I worked for a battery lab I did experiments where I discharged cells to below 0V.

    In a previous job I once evaluated some returned product that wasn't having the best battery life or wasn't working right. It was specialized expensive equipment that used regular alkaline batteries.

    TL;DR: ordinary batteries can have negative voltage if you don't give a fuck and just mix your old and new ones in a drawer before you put them into your high-cost life-saving equipment.
