Since a couple of months I have noticed that when doing a plan it is properly calculated. Let's say 300km starting at 100% and arriving at 20%. When starting to navigate doing the travel, if the cell phone with the ABRP app is not connected via OBD to the car, it is calculating wrong the car consumption. For example, after 100km the car is at 80% but at the app it is indicated that the level is at 60% and arrival SoC will be 0. Finally it is indicating that the travel is not any more viable. If replanning, then it is calculating right again the travel, starting at 80% and arriving at 20%, but again when navigating is considering a much higher consumption.

When used with the OBD there is no problem as it is reading the real car data. However, I was using before the app with no issues. Now this is happening to some EV6 cars as far as it has been commented in some user forum.
