That statement is invalid.

Explanation:

Most computers with batteries will not use every last bit of battery then shut down. A small amount is preserved so the computer can completely shutdown to avoid data loss. Just because a screen has gone black does not mean it has run out of power. It could also be in sleep mode, or some other state while not in use.
