The energy app is pretty good, it fits pretty well with my double policy but I don't look at it anymore, since it requires diverting my attention moreso than glancing ant the estimate, and additional tapping to bring it up.

As a rule of thumb I halve the EPA estimate in winter and 2/3-3/4 it in summer.

I have had no range issues doing this for the 130000km + I have owned the vehicle.

Edit: If I'm going to tap, I check the Wh/km, as that is what I'm used to. It was better before they removed it from the swipe, but hey, we gotta fill those sprints somehow.
