Depending on how fast the world comes to an end your not going to notice anyway. Or, if the world comes to an end real slowly, your going to run out of battery, and start seeing how everything around you fades out of existence.
That might be the new definition of hell. Caught in the "twilight-zone" right before the world ends. Nothing works, but you got everything. From time to time you find a few not completely dead batteries, and get a short burst of entertainment...
