I wouldn't make a habit of it, but letting it drain completely every now and then should be a problem. Be advised that when I say "completely" I mean until the phone shuts itself off. When it does this there is usually 5% charge left. If you let the device sit in this state for a few days and let the battery drain to 0%, you run the risk of causing damage to the battery up to having it no longer able to charge at all.
