I believe Google Maps and Apple Maps should tell you when to charge your phone to get home or have enough to go to the next service station.

I commute to university. When I get to the petrol station closest to it, my phone usually has between 3% and 8% battery life.<br><br>The charging stations are about a kilometre behind it. If I try to go there at this time I will either barely have enough battery to use Google Maps to get there or my phone will die before I get there, so I charge at the petrol station and lose 5 or 10 minutes and pay more for the electricity.<br><br>I don't know how they do the calculations to find the best route, so I'm not sure if it would be possible to do.<br><br>&#x200B;
