> if one day we have batteries that charge in 15 minutes

We're actually pretty close to that already. the Ioniq 6 Long Range adds 340km of range in 16 minutes. [0] The Porsche Taycan Plus adds 330km in 17 minutes [1]

How much battery life do you lose if you always fast charge? I thought batteries strongly prefer the kind of slow overnight charging that needs a garage.

Tesla used to tell users to avoid overusing the fastchargers, but they no longer include such language on the site.

A recent study by Recurrent Auto which looked at data from 12,500 Tesla vehicles said that there is "no statistically significant difference in battery degradation between Tesla Model 3 vehicles that charged at least 90% of the time using Superchargers and Model 3 vehicles that charged no more than 10% of the time using Superchargers."

Other brands might have different technology and might degrade differently. Tesla's aren't the fastest chargers, so perhaps the data for Ioniq or Porshe would be different.
