An EV for example: if the car has 10% charge left, does the battery have less power or amps or whatever than it does when it’s at 90%? Or an iPhone at 20% vs 80%…same question. Or, from the battery’s perspective, even to 1% left, it’s either on or off, regardless of charge remaining?

The voltage drops as the battery runs down. That’s how your device knows what the charge is, it can tell that the voltage is dropping. 0% is the critical threshold where it drops below the voltage required to reliably power the device.
Most devices will actually power down before that happens so that the battery doesn’t fully discharge, so their “0%” isn’t truly too low to power the device.
