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.

Correct me if I'm wrong, but as far as I know there haven't been significant changes in Li-Ion and LiPo batteries aside from extra density - which would only increase the effect. But it seems like solid-state batteries are starting to hit the real world now

    I bet thats wrong, but I know ….

    There've been usage changes

    • iPhone has “Optimized Charging” where it predicts usage and tries to keep about 80% charge until it expects you to use it
    • iPhone has “Adaptive Performance “. Maybe not charging but tries to gradually ramp to “low power mode” to be gentler on the battery
    • all phones likely have refined charging curves to match battery technology
