Using it until you get the low battery warning does not fully discharge it. You can't discharge it to the point at which damage might occur.

Also, the device measuring the battery, measures fully charged levels, and tells how empty a cell is, via the voltage readout.
It doesn't need to know what the minimum battery voltage is, as a lithium battery that's worn or empty will just put out less volts.

The relationship between voltage and battery charge level is device-specific (or, more accurately, battery-specific), and the firmware does need to calibrate it. This is well-established.
