To a degree you are right... you should never fully discharge these battries. BUT when the phone gets to a certian point where it cannot stay on due to low power it will shut itself off. The battery never actually gets "fully discharged". Doing so would risk the possiblity of "reversing the poles" of a cell and then you have a worthless battery. Most devices themselves prevent them from happening with voltage protction circuits. You can take these batteries probably down to .16 volts and never cause a problem. But less than that or 0 volts will casue issues.
