    Battery degradation is caused by extreme temperatures right? There is no way a fast charger will make your phone warm enough to cause any meaningful damage. (80% confidence)

      Extreme temperatures AND high C (coulomb) rates. Not really a problem on most smart phones. But you’d have to charge from 0-100% in under 20 minutes (above 3 coulomb) for that to become a real problem

        My one plus can charge 0 to 100 in about that time.

        It does this by moving some of the charging circuit into the charger and having 2 cells in the battery.
