I agree that the length of the PSP power cord is more of an inconvenience than the battery life. I've not had any issues with the latter.
No, you just lose your current progress. While the PSP takes the more forgiving route of stopping playability at an earlier point, and using the leftover battery power to keep your current game progress intact, something it can do for a surprisingly long time with the final fragments of battery power before it is drained completely and you lose everything since your last save.
