So after ..popular demand, I depleted the battery today from 80% to 1%. I didn't notice tbh, otherwise I wouldn't have left it to drop that much, I will try not to do it ever again.
Long story short, a trip consisted of 2 legs in both directions, with 15 km of motorway and 60 km of b-road plus city streets. EV for most of the time, it covered about 100km with electric only. Super quiet. Charging now, hopefully w very long trip awaits for me tomorrow, charging to 100%, needs 9hrs.
