Well if you do it every time at like 2-3C, you’re talking maybe 500 cycles compared to 1000 cycles at a slower charge rate. Depends on other stuff, too. Depth of discharge and max charge voltage are both even larger effects, but it still matters. (Knowing the exact chemistry of your phone’s battery can make a difference here, of course.) https://www.mpoweruk.com/life.htm https://www.mpoweruk.com/life.htm Fast charging from, say, 10% to 50% probably is a fairly small effect compared to trying to fast charge to 100%.
