I had posted these nos couple of days back before the 202328 update
Post the update, these are the nos after charging today.
25-66% - Around 31 mins 66-70% - 5.5 mins 70-75% - 11 mins 76-80% (including trickle) - 22.5 mins
25-80% - 1 hour 10 mins
This is the 2nd time I have encountered these speeds. So yes, the charging speed has indeed decreased. I guess this is done to discourage charging beyond a certain % so that only the in emergency situations would the rider spend 40 mins charging from 65-80%.
