that’s because for those cases the power draw is hard to predict. in case of your phone, the BMS might be lying and also the state of health of the cell might not be accounted for, but it’s more likely that some apps are juat power hungry. as for the EV, it’s doing the same thing as an ICE car, it predicts the range based on your last x kilometers, if you step on the throttle your range will deteriorate as you reach higher speeds and drag increases. a traditional car will start reducing the estimated range as well. I imagine that the aviation industry is much better at predicting and controlling the power draw, therefore the range won’t be so unpredictable. it’s not the cells that are unpredictable, it’s their end user.
