    Is there any data showing the real world effects of high speed (>60W) charging compared to the normal Samsung/Google approach after multiple years?

    I’ve always limited my charges to 80% but I’ve heard the argument that phones that charge quickly stay warm for a shorter period of time which lessens the potential negative impact of that kind of charging.

      high speed charging is a separate issue to charge voltage.

      I don’t have data at hand, but it is generally easier on lithium ion batteries to charge (and discharge) slower. I believe compared to charge voltage, that is a relatively small effect assuming the product is designed for it and manages things like heat. In a product where heat is poorly managed and builds up during slow charging, all bets are off I suppose

      charge voltage on the other hand has a well studied effect on battery longevity. reducing the max charge voltage (or increasing the minimum discharge voltage), can extend the number of cycles the battery will last without degrading in a huge way, more than doubling cycle count (depending on where those limits are set, ofc.
