First, current generation of Li-ion (and Li-Poly) has no 'memory effect' problem (it mainly affect NiCd battery, even NiMH has very little problem with memory effect). There is absolutely no need to fully drain Li-ion battery. In fact, you should NOT fully drain Li-ion battery all the time. The one weakness Li-ion battery has, is it must maintains a minimum voltage to make sure the chemicals inside will not go into 'run-away' mode (that is, the chemical process that produces the electricity becomes overdriven and can no longer be reversed / charged). It is possible (though not likely) that your action to drain the battery cause the battery to overdraw thus damage the battery and causeing it to lost the ability to hold charge. A new Li-ion battery will benefit most if you recharge it often to ensure the chemicals stay as active as posible. You can occasionally drain the battery to 5~10% to complete a power cycle, but you should avoid fully drain all the time. If you draw the battery too hard and cause it to go below its minimum voltage, the battery will be damaged.

Second, I do think you might have a lemon in your hand and you should return it for a replacement. However, I'll also suggest you check the dock connection (both cable and socket) first to make sure it isn't obstacled by things like dirt.

Third, just so you know, exporesure to extreme weather can damage battery as well. If it is too cold, some battery will refuse to charge.

Hopefully you can get it to run again
