As someone said Li-ion or Li-poly cells do not get a memory, and they do not need to be periodically fully discharged to reduce the risk of a momory, in fact it is a bad idea to fully discharge a Li-ion or Li-poly cell because it will not be able to work again.
However the device has a circuit that controls charging, and will not let the cell be discharged lower than say 3V. SO when you see a battery is empty, it is actually only aproaching 3V for example. And then the phone turns off.
By letting the phone run down several times in a row, you teach the charging circuit the actuall remaining capacity of the battery so that it can estimate the actual battery life.

Hmm iv let it die once and then plugged it in about 5 min afterwards... but im a little hesitant about doign it a lot in a row.. it did seem to help a little doing it once.. i guess i do have insurance t oget a new battery if i kill it lol
i might try it..
