EV batteries are very reliable at showing state of charge. Even if it says it has 1%, you can rely on having that whole 1% left.
In a cellphone you have just one cell, and the phone turned on can be pulling near its maximum power draw, so it's unstable and unpredictable.
In a BEV you have thousands of cells, so differences between individual cells average out, and you don't draw peak power unless you're racing (and the car is smart enough to not let you smoke tires at 1% battery).
