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 guys joke and all, but fast charge induces bigger heat and then translates in more harm for the batteries (which will affect more in hot places).

        If we want to close this discussion forever I think all the anxiety that comes from this subject at all is due to the fact we can’t easily replace the batteries, if we could (with the normal-ish battery sizes we have today), I don’t think this test would be even worth doing.

          While that seems obvious, I’ll disagree

          • phones have a charging curve that takes into account heat, battery level and probably more factors specific to battery health. Most of the additional charging speed is likely minimal effect
          • You can have a battery replaced on even the latest iPhone for $99 or less, and I expect most phones to be cheaper. Yeah it’s not really diy nor replacement cost only, but it’s just not that bad relative to the cost of the device. Sure I’d rather spend $20 and replace my own battery, but if I’m spending $1,000 on a new phone, then $99 every 3-4 years for batteries is just not that bad
